Forward & Reverse Relay Module


Cole Hersee Company, a leading manufacturer of electrical and electronic products for the vehicle industry, offers its Forward & Reverse Relay Module. Ideally suited for a multitude of applications where forward/reverse motor operation is necessary, including hoists, winches, lifts, snowplows, vehicle outriggers, and tarps. The Module is able to reverse the motor’s direction automatically when the control circuit is energized with a pulse from a momentary switch. The Module provides dynamic braking capability and is ignition protected. The Module carries a heavy load current; up to 70A at 12V DC (intermittent). Fully sealed to IP-67, the module can withstand very harsh environments.


High performance silver tin oxide contacts assure long cycle life. • 70A at 12V DC intermittent, max On time 5 mins; Off time 3 mins; 50A at 12V DC continuous. • Load current inrush: 150A. Pull-in voltage 7.8V max. • Low coil current draw. Coil resistance 82Ω ±10%. • Vibration resistance: 10-55Hz. Double amplitude 1.5mm. • Environmental: -40C to 85C. Rust and moisture-resistant plastic housing. Fully sealed to IP-67 with high strength epoxy for total moisture protection. • Ignition protected. • Tin-plated brass studs and hardware for corrosion resistance. • Dielectric strength: 500V RMS between coil and contact. • For intermittent operation, control switch should be Mom On-Off-Mom On; for continuous operation On-Off-On
