GE IS200SHRAS2A Analog Input/Output Terminal Board

Product Description

GE IS200SHRAS2A (SHRA) is a HART-enabled analog input/output terminal board for GE Mark VIe distributed turbine control system, paired with PHRA I/O Pack. It provides 10 analog input channels plus 2 channels of 4-20mA analog output with HART pass-through capability for bi-directional communication with field HART smart transmitters. It retrieves process variables, device diagnostics and configuration parameters. Supports 2-wire, 3-wire and 4-wire transmitters. Equipped with high-density Euro-block terminal blocks and on-board identification chip for automatic board recognition and channel diagnostics by PHRA module. Simplex only, rack pluggable. Widely deployed on gas and steam turbine BOP balance-of-plant loops for pressure, level and temperature measurements. OEM production discontinued and available as spare parts for legacy power plant turbine control systems.
