The SGC 420/421 controllers are modern genset controllers for both AMF applications with a mechanical and electrical controlled engine (CANbus) plus AMF applications with electronic governor.
The controllers provide you with a user-friendly interface and full graphics LCD and include voltage and frequency measurement for mains and gensets, and electrical load measurement (true RMS). 
Configurable analogue and digital inputs/outputs are provided for various features. 
Modbus over RS-485 and CAN ports 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. 
The controller monitors engine safety, electrical load, site battery backup voltage and shelter temperature to reduce fuel consumption. 
Configure parameters easily from a PC using DEIF Smart Connect utility software. Connect to the PC through the controller’s USB Type B port. 
In addition, the SGC 421 controller also includes an integrated electronic governing function.
