Epec GL84 Responder/Slave Unit


Epec GL84 Responder/Slave Unit is a responder product for centralized control system architecture where one master/central unit controls multiple responders. GL84 has 27 GND pins for sensors and actuators and CAN1 is also routed to M12 connectors for easy wiring. GL84 Responder/Slave Unit’s cycle time is extremely fast – it feels like the I/O is actually connected to the master/central unit.

The unit has a housing and connector solution that enables plenty of I/O in a compact housing. The casing works to protect the electronics against mechanical wear. The leak-proof aluminum housing has also been widely tested against different environmental conditions, the housing is even protected against high-pressure washing (IP69).

The unit is equipped with a signal LED for diagnostics. The unit’s LEAVYSEAL connectors have integrated strain relief and lever locking that are designed for high vibration environments. Single Wire Seal (SWS) system also ensures safe and robust sealing for wires.
