Frequently Asked Questions
Q: What types of DC motors are compatible with this motor forward/reverse controller?
A: This controller is designed for DC motors operating at 12V. The relay is rated at 30A, making it suitable for a wide range of DC motors used in robotics, gate openers, linear actuators, conveyor belts, and similar automation applications, as long as the motor's current draw does not exceed 30A.
Q: Can I set a specific time delay before the motor starts or reverses direction?
A: Yes. The time delay is fully adjustable across three ranges: 0.1 to 999.9 seconds, 1 to 9999 seconds, or 1 to 9999 minutes. This allows you to customize exactly how long the controller waits before switching motor direction or stopping, making it highly versatile for automation sequences.
Q: What is the difference between the normal mode and energy-saving mode?
A: In normal mode, the standby current is 22 mA and working current is 109 mA. In energy-saving mode, standby drops to just 7 mA and working current to 76 mA. Energy-saving mode is ideal for battery-powered or low-consumption setups where minimizing idle power draw is important.
Q: How many control modes does this relay controller support?
A: The controller supports 6 functional modes, along with two input trigger types — low pulse trigger and low level trigger — giving you flexible options for integrating it into different automation and motor control circuits.
