30A RC PWM Forward Reverse Relay Module | DC10-60V Motor Control
30A RC PWM Forward Reverse Relay Module | DC10-60V Motor Control
30A RC PWM Forward/Reverse Control Relay Module — HC-30ASP
Take precise command of your RC model motors with the HC-30ASP 30A RC PWM Relay Module. Built around two heavy-duty 30A relays, this compact module translates standard RC PWM signals into reliable forward and reverse motor control — perfect for RC cars, boats, crawlers, and custom DC motor projects operating between 10V and 60V.
Key Features
- Dual 30A Relays — Handles demanding motor loads up to 30A per relay for robust, dependable switching.
- Wide Voltage Range — Compatible with input voltages from 10V to 60V DC (maximum board voltage 80V); suits a broad range of battery packs.
- Standard PWM Signal Input — Accepts RC-standard positive pulse width signals from 0.8ms to 2.2ms; activates when signal is <1.3ms or >1.7ms for clear, noise-resistant triggering.
-
Two Model Options:
- 4-Interface Model — Straightforward forward/reverse motor control. Center terminals (+/−) connect to your battery; side M terminals connect to the motor.
-
8-Interface Model — Two switchable working modes via onboard switch:
- D Mode: Two independent signal lines each control one relay independently.
- S Mode: Single white signal line toggles between L and R relays for forward/reverse motor direction switching.
- Compact Form Factor — Measures just 63mm × 56mm × 25mm; easy to integrate into tight RC chassis builds.
- Convenient Signal Lead — Approximately 20cm signal line included for easy receiver connection.

Frequently Asked Questions
Q: What is the maximum current this RC PWM relay module can handle?
A: The HC-30ASP relay module uses two 30A relays, so each relay channel can handle up to 30A. Ensure your motor's current draw stays within this rating for reliable, long-term operation.
Q: What battery voltage range is compatible with this relay module?
A: The module supports input voltages from 10V to 60V DC. The absolute maximum board voltage is 80V, but the recommended maximum battery voltage is 60V for safe and stable performance.
Q: What is the difference between the 4-interface and 8-interface models?
A: The 4-interface model is designed exclusively for simple forward and reverse motor control using one PWM signal. The 8-interface model adds a mode switch: D mode lets two signal lines independently control two relays, while S mode uses a single signal line to toggle the motor direction — giving you more flexibility for complex RC builds.
Q: Which RC receivers is this module compatible with?
A: This module is compatible with any standard RC receiver that outputs a PWM signal in the 0.8ms to 2.2ms range — which covers the vast majority of hobby-grade RC transmitter/receiver systems (e.g., 2.4GHz RC controllers used for cars, boats, and crawlers).
