DC Motor Forward/Reverse Controller 4V–40V 20A Wide Voltage Module
DC Motor Forward/Reverse Controller 4V–40V 20A Wide Voltage Module
DC Motor Forward/Reverse Controller Module – Wide Voltage 4V–40V, 20A
Take full control of your DC motor applications with this versatile Wide Voltage DC Motor Forward/Reverse Controller Module by Gaqqee. Engineered for precision motor control, this compact drive module supports both self-locking (P0) and jog (P1) operating modes, limit switch integration, and automatic locking — making it ideal for lifting motors, linear actuators, automation systems, and DIY electromechanical projects. Compatible with a broad input voltage range of 4V to 40V (recommended 6V–36V) and a peak output current of 20A, it handles demanding motor control tasks with ease.
Made in Mainland China.
Key Features
- Wide Voltage Compatibility: Operates across DC 4V–40V (recommended 6V–36V); no need to specify voltage at purchase — one module covers 5V, 12V, 24V, and beyond.
- Forward & Reverse Control: Supports bidirectional DC motor rotation via external switch signals (K1/K2).
- Limit Switch Support: Integrates SW1/SW2 limit/stop signals for precise positional control and automatic halting.
-
Two Operating Modes:
- P0 – Self-Locking (Standard): A brief trigger keeps the motor running continuously until a limit or reversal signal is received.
- P1 – Jog Mode: Motor runs only while the signal is active; releases immediately upon signal removal (press to run, release to stop).
- Parameter Memory: Preserves settings during power loss, so your configuration is retained after power cycling.
- Automatic Locking Mode: Engages motor lock automatically as required by your application logic.
- NPN Sensor Compatible: Accepts three-wire NPN-NO type sensors on K1, K2, SW1, and SW2 inputs.
- Long Operational Lifespan: Rated for over 150,000 cycles for dependable long-term use.
- Low Power Consumption: Only 0.6W under load, 0.1W in static mode.

Frequently Asked Questions
Q: What is the difference between the P0 and P1 operating modes on this DC motor controller?
A: The P0 (Standard/Self-Locking) mode means a brief press of the forward switch (K1) initiates continuous forward rotation — even after releasing K1, the motor keeps running until it receives a reverse (K2) or a stop/limit signal (SW1). The P1 (Jog) mode is press-and-hold: the motor runs only while K1 is held down and stops immediately when released. Choose P0 for automated reciprocating or continuous operation and P1 for manual, incremental movement.
Q: What voltage and current ratings does this wide voltage motor controller support?
A: This module supports an input voltage range of DC 4V to 40V, with a recommended operating range of 6V to 36V for reliable performance. It is fully compatible with common DC voltages including 5V, 12V, and 24V without any configuration change. The maximum output current is 20A at 12V and 10A at 24V, supporting DC motors up to approximately 80W (based on locked-rotor current).
Q: Can this DC motor forward/reverse controller achieve automatic reciprocating (back-and-forth) operation?
A: The module does not have a built-in timer, so it cannot independently perform timed auto-reciprocation. However, by connecting a start switch and a start-point limit switch to K1 and an endpoint limit switch to K2 (with SW1/SW2 left unconnected), the module can achieve infinite reciprocating motion between two points A and B. All switches used must be normally open (NO) type.
Q: Can I connect NPN sensors to the signal inputs on this motor controller?
A: Yes. The signal inputs (K1, K2, SW1, SW2) are active-low and accept three-wire NPN-NO (normally open) type sensors. Any voltage below 2V on an input is interpreted as an active signal. This makes the module fully compatible with standard proximity sensors, limit switches, and similar NPN-output control devices.
