Description
⚙️ The GE IS220PHRAH1A is a HART-enabled Analog I/O Pack designed for the GE Mark VIe turbine control system. The module provides 10 analog input channels and 2 analog output channels, with HART communication available across the I/O channels. The first eight analog inputs can be configured for ±5 V or 4–20 mA signals, while inputs 9 and 10 support ±1 mA or 4–20 mA configurations. The two analog outputs provide 4–20 mA signals. The PHRA communicates with the Mark VIe controller through one or two Ethernet IONet connections and is designed for simplex operation with compatible SHRA terminal boards.
