IS220PAICH1B Mark VIe Analog Input/Output Module

The GE IS220PAICH1B is a high-precision Analog Input/Output (PAIC) Pack designed for the Mark VIe Speedtronic turbine control system. It serves as a distributed field I/O node that interfaces analog sensors and actuators directly with the Mark VIe controller over a dual-redundant Ethernet I/O network. The PAICH1B is the updated technology replacement for the legacy IS220PAICH1A, offering identical form, fit, and function with enhanced componentry for improved reliability and noise immunity. It provides 10 analog input channels and 2 analog output channels, enabling precise signal acquisition from pressure transmitters, temperature sensors, and flow meters, while delivering control signals to valves, positioners, and actuators.
