DEIF SCM4-2 Measurement and Synchronization Control Module
DEIF SCM4-2 is a high-precision measurement and synchronization control module of the Danish DEIF Delomatic-4 (DM-4) system. Rack backplane installation, 12TE width, is the signal acquisition unit of the DM-4 power station control system, which works in conjunction with the PCM4.1 processor module.

Main function:
- Collect three-phase voltage and current signals from the generator and bus, and complete high-precision measurements of electrical parameters such as voltage, current, frequency, active power, reactive power, and power factor;
- Implement synchronous detection and verification of generator sets for grid connection, providing criteria for closing and grid connection;
- Built in fast protection logic, completing fast protection for overcurrent, overvoltage, undervoltage, frequency abnormality, etc., and can directly drive the circuit breaker to trip;
- Upload measurement data and fault status to the PCM4.1 main control module through the backplane bus;
- Collect feedback signals of circuit breaker positions, complete switch status monitoring, and use them for multi machine parallel connection and load distribution logic operations;
- As a hardware spare part, it is used for replacement and repair of damaged SCM4-2 modules in the DM-4 system.
Main product range
- Control system (DCS/PLC/CNC): panel controller, HMI and human-machine interface, industrial PC, CPU processor module, communication module, analog/digital I/O module
- Drive and motion control: frequency converter, servo drive, servo motor, power module
- Robot spare parts: key spare parts such as robot control board, axis computer, servo unit, I/O module, etc
- State monitoring and safety system: vibration monitoring system, safety instrumented system (SIS), redundant controller
Application Industry
