IS200SRLYH2ABA | General Electric Simplex Relay Output Terminal Board

Description

IS200SRLYH2ABA is a Simplex Relay Output Terminal Board from General Electric, part of the Mark V series designed for gas turbine control systems. As a member of the RST analog I/O board family, it shares core functionality with similar models including IS200SRLYH2A and IS200SRLYH2AAA. The board is engineered to scale and condition a wide range of analog signals read from terminal boards installed on I/O cores R1, R2, and R3. Supported signal types include LVDT inputs, servo valve outputs, thermocouple inputs, 4-20 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator and line signals. It features dedicated connectivity: select signals are written to the STCA board via a 3PL connector, while a JE connector enables transmission and reception of generator and line signals with the TCQC board. Additionally, the board provides precise scaling and conditioning for critical 4-20 mA input signals such as compressor stall detection signals and fuel flow pressure signals, ensuring reliable data processing for gas turbine control operations.
