Connect your RS232 serial port from the host controller (PLC, industrial computer, or microcontroller board) to the module's RS232 connector using a standard serial cable. Configure the module's slave address and baud rate using the onboard DIP switches or configuration software to match your host controller settings. Each relay output terminal can be wired directly to the control coil of contactors, solenoids, or directly to low-power loads, with the module providing galvanic isolation from the control circuit.\u003c\/p\u003e\u003cp\u003eImplement Modbus RTU commands in your host controller software to read relay status and send switching commands using standard function codes 01 (Read Coil Status) and 05 (Write Single Coil). Test communication by sending a simple command to toggle a relay and verify the physical relay activation with an audible click. For multi-module setups, assign unique slave addresses to each module and implement proper error handling for timeouts and CRC failures. Always include protective wiring such as fuses on relay output circuits and use proper cable shielding for RS232 lines in electrically noisy industrial environments to ensure reliable long-distance communication.\u003c\/p\u003e\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eThis relay module operates as a Modbus RTU slave device, converting serial RS232 commands into four independent relay switching outputs.

Identify the analog input terminals on the module, typically labeled as positive and negative current loop connections. Connect the 4-20 mA signal source (such as a pressure transmitter or temperature sensor) to these terminals, ensuring correct polarity to avoid triggering the reverse polarity protection. The module requires a stable 3.3V to 5.0V DC power supply, which should be connected to the designated power pins on the Click header. Once powered, the module will output a proportional voltage on its analog output pin, typically ranging from 0.8V at 4 mA input to 4.0V at 20 mA input.\u003c\/p\u003e\u003cp\u003eConfigure your Parallax Propeller microcontroller to read the analog output voltage using its built-in analog-to-digital converter or an external ADC module. Implement software scaling to convert the raw ADC readings into actual current values or engineering units. For example, if your ADC returns a 10-bit value from 0 to 1023, map this to the 4-20 mA range using the formula: Current (mA) = 4 + (ADC_Value \/ 1023) × 16. Test your system with a calibrated 4-20 mA signal source or precision current loop simulator to verify accuracy across the measurement range. Apply the optional low-pass filter by connecting a capacitor between the output and ground if additional noise filtering is required for your specific application. Document your calibration data and store it in the Propeller's EEPROM for future reference and system diagnostics.\u003c\/p\u003e\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eThe Parallax 64201 4-20 mA T Click operates on the principle of precision current-to-voltage conversion using a high-accuracy transimpedance amplifier circuit. The module accepts a standard 4-20 mA analog input signal and converts it to a proportional voltage output that the Propeller microcontroller's analog-to-digital converter can measure with high resolution. The 4 mA signal represents the minimum sensor reading (0 percent), while 20 mA represents the maximum reading (100 percent), providing a standardized industrial measurement range that has been the industry standard for over four decades. This Click board features integrated protection circuitry including reverse polarity protection and current limiting to safeguard both the module and connected microcontroller from electrical faults.\u003c\/p\u003e\u003cp\u003eWhat distinguishes the Parallax 64201 is its tight integration with the Parallax ecosystem and its exceptional noise immunity in electrically noisy industrial settings. The module employs a low-pass filter design that attenuates high-frequency noise while preserving signal fidelity, critical for applications where electromagnetic interference from motor drives and power distribution equipment could otherwise corrupt measurements. The Click form factor ensures compatibility with standard Parallax Click adapter boards, allowing rapid prototyping and modular system design. The precision resistor network maintains measurement accuracy across the full 4-20 mA range with minimal zero-point and span drift, ensuring reliable long-term operation in temperature-varying industrial environments.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cdetails\u003e \u003csummary\u003eWhat is the difference between 4-20 mA and 0-10V sensor interfaces?\u003c\/summary\u003e \u003cp\u003eThe 4-20 mA current loop standard provides superior noise immunity over long cable runs because current is less susceptible to voltage drops and electromagnetic interference than voltage signals. The 4 mA offset also allows detection of broken sensor wires (zero current indicates a fault), whereas 0V in a voltage system could indicate either zero measurement or a disconnected sensor. Industrial facilities prefer 4-20 mA for distances exceeding 100 meters or in electrically noisy environments. The Parallax 64201 converts this current standard to voltage for microcontroller processing.\u003c\/p\u003e \u003c\/details\u003e\u003cdetails\u003e \u003csummary\u003eCan I connect multiple 4-20 mA sensors to a single Propeller using this Click module?\u003c\/summary\u003e \u003cp\u003eEach Parallax 64201 Click module accommodates one 4-20 mA input signal. To monitor multiple sensors, you have two options: use multiple Click modules on different Click adapter sockets or ports of your Propeller board, or implement a multiplexed analog input system using external switching circuitry. For most applications with four or fewer sensors, using multiple Click modules is the simplest and most reliable approach, as each module provides independent signal conditioning and protection.\u003c\/p\u003e \u003c\/details\u003e\u003cdetails\u003e \u003csummary\u003eWhat cable specifications should I use for connecting remote 4-20 mA sensors?\u003c\/summary\u003e \u003cp\u003eUse twisted-pair shielded cable rated for industrial environments, typically 18 to 22 AWG (American Wire Gauge) for distances up to 500 meters. The shield should be grounded at the sensor end only to prevent ground loops. For distances exceeding 500 meters or in extremely noisy environments, use 16 AWG cable or consider installing a repeater transmitter at the sensor location. Ensure the cable is routed away from high-voltage power lines and motor drives. Verify cable impedance is below 100 ohms per 1000 feet to maintain signal integrity and minimize attenuation.\u003c\/p\u003e \u003c\/details\u003e\u003cdetails\u003e \u003csummary\u003eHow do I calibrate the Parallax 64201 for maximum accuracy?\u003c\/summary\u003e \u003cp\u003ePerform two-point calibration using a precision 4-20 mA current loop simulator or calibrated signal generator. First, apply exactly 4 mA and record the ADC reading from your Propeller. Then apply exactly 20 mA and record the second ADC reading. Use these two data points to calculate the linear scaling coefficients for your software: Slope = (20 - 4) \/ (ADC_20mA - ADC_4mA), and Offset = 4 - (Slope × ADC_4mA). Store these coefficients in EEPROM and apply them to all subsequent measurements. Recalibrate annually or whenever you replace the module to maintain measurement accuracy within the specified ±2 percent tolerance.\u003c\/p\u003e \u003c\/details\u003e\u003cdetails\u003e \u003csummary\u003eWhat protection does the module provide against electrical faults?\u003c\/summary\u003e \u003cp\u003eThe Parallax 64201 includes reverse polarity protection that prevents damage if the 4-20 mA signal connections are accidentally swapped. The module also incorporates current limiting circuitry that protects against overcurrent conditions, such as when a sensor cable is short-circuited. These protections prevent damage to both the Click module and the Propeller microcontroller. However, the module does not protect against overvoltage conditions exceeding the specified supply voltage range, so always use a properly regulated power supply within 3.3V to 5.0V specifications.\u003c\/p\u003e \u003c\/details\u003e\u003ch2\u003eCustomer Support\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eEmail:\u003c\/strong\u003e techdepotindia@gmail.com\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhatsApp:\u003c\/strong\u003e Available for setup and troubleshooting help\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOrder your Parallax 64201 4-20 mA T Click today and start building your next project.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eBuy Parallax 64201 4-20 mA T Click Online in India\u003c\/h2\u003e","brand":"The Tech Depot","offers":[{"title":"Default Title","offer_id":48743602422017,"sku":"TTD-7878","price":3089.9,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/1577\/3185\/files\/96c1139573473dbf9b524f2e9ecf3987.jpg?v=1778060262"},{"product_id":"parallax-64200-4-20-ma-r-click","title":"Parallax 64200 4-20 mA R Click","description":"\u003cp\u003eOur team in Bengaluru is available reliable to support your journey from product selection to project completion.\u003c\/p\u003e\u003cp\u003eThe Parallax 64200 4-20 mA R Click is a precision analog current loop measurement module designed for industrial automation and sensor interfacing applications.
