GC 250

Despite the compact dimensions, GC250 includes the main engine and alternator protections like oil pressure, coolant temperature, frequency, voltage, current, power and fuel level.

The same controller can be used for electronic engines with CAN interface J1939 and MTU MDEC protocols, and MPU engines (non-electronic) as well.

Configuring the inputs, outputs and protections, GC250 can be easily adapted to suit a wide range of applications.

GC250 offers a wide, graphic display 128 x 64 pixels providing icons for alarms/warning and for signalling the status of the engine, controller and data logs as well.

All the parameters can be set directly by the controller’s keyboard or, alternatively using the free software tool (BoardPRG3), available from SICES’ website.
