GE IS200SCSAS1A I/O Expansion Board

GE IS200SCSAS1A I/O Expansion Board

Functional Description

The YSIL module requires three SCSA I/O expansion boards be connected through serial links to the TCSA

terminal board. Each SCSA provides ten 4-20 mA inputs and ten 24 V dc transmitter power outputs, six 4-20

mA inputs for externally powered transmitters, three thermocouple inputs, three contact inputs, and three

contact outputs. The YSIL can use any of the 4-20 mA analog inputs on the SCSA (AnalogInput01_R,S or T

through AnalogInput16_R,S or T TMR input sets) in the Emergency Trip Relay (ETR) logic string.
