12V DC Motor Driver Board Forward Reverse Control Relay Module
12V DC Motor Driver Board – Forward & Reverse Control with Programmable Delay Timing Relay
Take precise control of your DC motor projects with this compact and versatile 12V DC Motor Driver Board. Featuring a built-in programmable delay timing relay and low-level trigger input, this module makes it straightforward to control the forward and reverse direction of any DC 12V motor rated up to 10A — all from a single, easy-to-wire board.
Whether you're building an automated gate, a conveyor system, a robotics project, or any custom DC motor application, this driver board delivers reliable, interference-resistant performance thanks to its optical coupling isolation between input and output.
Key Features
- Programmable Delay & Timing: Set your timing parameters once — values are stored in memory even after power-off, so you never have to reprogram on restart.
- Low-Level Trigger Input: Compatible with NPN sensors, proximity switches, key switches, and push buttons for flexible integration into any control system.
- Optical Coupling Isolation: Input and output are fully isolated via optocouplers, significantly reducing electrical noise and improving anti-interference performance.
- High-Current Output: Handles DC motors up to 12V / 10A, making it suitable for a wide range of motorized applications.
- Dual-Sided PCB Layout: Front side features SMD components, a digital display tube, and control buttons; rear side houses the relays, KF7.62 screw terminals, and electrolytic capacitors for clean panel mounting.
- Robust Screw Terminals: KF7.62 terminals with screw-crimped large connectors ensure secure, tool-assisted wiring for worry-free connections.
- Compact Form Factor: Measures just 83mm × 46mm × 27mm — easy to fit into enclosures or mount on a panel.

Frequently Asked Questions
Q: What type of motors is this 12V DC Motor Driver Board compatible with?
A: This driver board is designed for DC motors operating at 12V with a maximum current rating of 10A. It controls the forward and reverse direction of the motor via the onboard relay switching mechanism.
Q: Does the programmable delay timing setting save after the power is turned off?
A: Yes — once you set your delay and timing parameters, the module stores them in non-volatile memory. Your settings are retained even after a full power-off cycle, so the board is ready to go immediately upon the next power-up.
Q: What trigger signal does this relay module require?
A: The module uses a low-level trigger, meaning it activates when the signal input is pulled LOW (close to 0V). It is compatible with NPN-type sensors, proximity switches, microcontroller outputs, PLC outputs, and standard push buttons or key switches.
Q: Why is optical coupling (optocoupler) isolation important in this module?
A: Optocoupler isolation separates the input control circuit from the output power circuit electrically. This prevents high-voltage spikes or electrical noise from the motor side from interfering with or damaging your control electronics, resulting in a more stable and protected system.
Q: Can this module be mounted on a panel or inside an enclosure?
A: Absolutely. The board is designed with panel installation in mind — the relays, terminals, and electrolytic capacitors are on the rear side, while the digital display and buttons face forward, making it ideal for flush or surface panel mounting in a control box or enclosure.
