Functions as a Normally Off relay or as a Latching Relay, depending on which wires are connected by the user.

For use on all vehicle electrical systems such as heavy truck, off-road, construction, material handling, refuse collection or marine. 200A at 12V DC - big enough to control most onboard equipment.

  • The Dual Relay is non-arcing and ignition-protected. 
  • Solid-state reliability – withstands conditions that would ‘kill’ an electromechanical solenoid – and stands up to roadsplash and vibration. 
  • Low control current and quiescent current make this Dual Relay ideal for idle reduction, battery saving, and electronic control applications. 
  • Allows electronic systems to directly drive a high current switch without the need for an extra relay. 
  • Easy to install. 
  • Safe operation – protected against misconnect, overcurrent, short circuit and overheating. Optional; remote status LED gives warning to vehicle operator.
