Forward/Reverse Motor Controller Board 12V 24V Motor Two Relay Delay Timing Cycle YYB-5 Module
Forward/Reverse Motor Controller Board 12V 24V Motor Two Relay Delay Timing Cycle YYB-5 Module
The YYB-5 is a dual-relay motor controller module engineered for precise bidirectional DC motor control with programmable timing delays. Industrial technicians, automation engineers, and hobbyists rely on this module to manage forward/reverse motor operations with cycle timing accuracy up to 0.1 seconds. This controller solves the critical challenge of automating repetitive motor sequences without requiring complex PLC programming or microcontroller integration.
Product Overview
The YYB-5 Forward/Reverse Motor Controller Board operates on a dual-relay architecture that switches motor polarity to achieve forward and reverse rotation while maintaining precise timing control. The module accepts 12V or 24V DC input power and uses two independent relay channels to manage motor direction and cycle timing. Each relay is rated for 10A at 250V AC or 30V DC, making it suitable for controlling motors up to 240W at 12V or 480W at 24V. The timing circuit utilizes a 555-based astable oscillator configuration with adjustable potentiometers for period control, delay adjustment, and duty cycle modification. This architecture eliminates the need for external timing circuits or software programming.
The module features integrated protection circuitry including flywheel diodes across each relay coil to suppress back-EMF spikes from inductive motor loads, preventing relay contact damage and extending component lifespan. The PCB layout follows industrial standards with clearly marked terminal blocks for motor input, power supply, and control signal connections. The compact form factor measures approximately 60mm x 40mm, allowing seamless integration into control panels, automation equipment, and robotics applications. Temperature stability is maintained across -10°C to +60°C operating range, ensuring consistent timing accuracy in varied industrial environments.

How to Use
Installation begins with identifying your power supply voltage and motor specifications. Connect the 12V or 24V DC power supply to the designated input terminals, ensuring correct polarity as marked on the PCB. The two relay output terminals connect directly to your DC motor leads; connect one motor terminal to relay contact 1 and the other motor terminal to relay contact 2. When relay 1 energizes, the motor rotates forward; when relay 2 energizes, the motor reverses direction. The timing potentiometer controls the duration of each relay activation cycle. Rotate the potentiometer clockwise to increase cycle time and counterclockwise to decrease it. Start with the potentiometer at the midpoint and adjust based on your required timing.
For delay-based applications, use the secondary delay potentiometer to introduce a pause between direction changes, preventing mechanical shock and extending motor bearing life. The module operates continuously once powered, cycling through forward and reverse states at your programmed intervals. For single-cycle operation or external triggering, connect a momentary switch across the control input terminals to manually activate the timing sequence. Always verify motor rotation direction before connecting to mechanical loads. If the motor rotates opposite to your requirement, simply swap the two motor terminal connections. Test the complete system at no-load condition first, then gradually apply mechanical load while monitoring relay contact temperature. Relay contacts should remain cool to touch; excessive heat indicates undersized relay contacts for your motor load.
Frequently Asked Questions
Can the YYB-5 controller handle AC motors or only DC motors?
The YYB-5 is specifically designed for DC motor control and cannot be used with AC motors. The relay contacts are rated for AC switching, but the timing circuit and control logic operate on DC principles. For AC motor control, you would need an AC motor controller with phase control or contactor-based switching. If you need to control an AC motor with forward/reverse capability, consider a dedicated AC motor starter or soft starter module rated for your motor horsepower.
What is the minimum and maximum timing range I can achieve with the potentiometer adjustment?
The YYB-5 potentiometer adjustment provides a timing range from 0.1 seconds to 99 seconds per cycle. The timing resolution is approximately 1 second for each 5-degree potentiometer rotation. For applications requiring timing precision below 0.1 seconds, you would need a faster microcontroller-based solution. For timing above 99 seconds, you can cascade two YYB-5 modules or use an external timer relay in conjunction with this module.
How do I know if my motor is within the power rating of this controller?
Calculate your motor's power consumption using the formula: Power (Watts) = Voltage (V) x Current (A). For a 12V motor drawing 15A, the power is 180W, which is within the 240W limit. The relay contacts are rated 10A maximum, so divide your motor's stall current by 10 to determine if the relay can handle it directly. If your motor exceeds 10A, you must use an external contactor or relay with higher current rating, using the YYB-5 to control the contactor coil instead of the motor directly. Always consult your motor's datasheet for accurate current specifications.
Can I use the YYB-5 to control multiple motors simultaneously?
Yes, the two relay outputs can control two separate motors independently, or you can wire both relays in parallel to control a single larger motor if the combined current does not exceed 10A per relay. For controlling three or more motors, you would need multiple YYB-5 modules or use the relay outputs to trigger external contactors rated for higher currents. Each relay operates independently, so you can program different timing sequences for each motor by using separate modules with different potentiometer settings.
