Description
Ideal for tarp or lift applications. Also used on hoists, hatches,
winches, snowplows, intake/exhaust fans, vehicle outriggers
and other reversing applications. Module automatically
reverses the direction of the motor when the appropriate
control circuit is energized with a pulse from a control switch.
Dynamic braking stops the motor when the switch returns
to Off. Low-profile module saves space. Studs are securely
anchored in epoxy.
Features and Benefits
Dynamic braking.
Carries a heavy load current.
Intermittent or continuous operation.
High performance silver tin oxide contacts assure long
cycle life.
Fully sealed to IP67 with high strength epoxy for total
moisture protection to withstand very harsh environments.
Ignition protected.
Tin-plated brass studs and hardware for
corrosion resistance.
For intermittent operation, control switch should be Mom
On-Off-Mom On; for continuous operation On-Off-On.
