Product Overview

The IS220PAOCH1BE (your input IS220PA0CH1BE is common transcription error, digit 0 / letter O) is the 8-channel analog output pack for GE Mark VIe turbine control platform. It communicates over IONet dual Ethernet to the Mark VIe controller, provides 4–20 mA / 0–20 mA current outputs with per-channel current feedback monitoring, used to drive valve positioners, fuel valves, lube oil control and auxiliary process actuators on gas / steam turbines. It supports simplex, dual redundant and TMR triplex architectures.
