SGC 120 & 121
Single genset controller
The SGC 120/121 controllers are modern genset controllers for AMF applications with an electronically controlled engine (CANbus) and AMF applications with electronic governor.
The controller stands out, featuring CANbus and Modbus plus it includes nine configurable inputs and six configurable digital outputs.
The controllers have a user-friendly interface and full graphics LCD. They include voltage and frequency measurement for mains and gensets, and electrical load measurement (true RMS). RS-485 and CAN port are available for remote communication. Start and stop gensets remotely using the Remote start/stop function.
Deep sleep mode is a useful feature that extends the battery lifetime by suspending the normal controller functions of when the genset is off.
Configure parameters from a PC using DEIF Smart Connect utility software. Connect to the PC through the controller's USB Type B port.
Besides, the SGC 121 controller also includes an integrated electronic governing function.
