GE IS220PAICH1B Mark VIe Analog Input/Output I/O Pack Module

The GEIS220PAICH1B is a combined analog input/output I/O pack designed for high-performance turbine control systems within GE’s Mark VIe platform.

It provides up to 10 analog input channels with flexible configuration options for voltage and current signals, along with 2 analog output channels for control loop actuation. Each module includes an embedded processor board and an acquisition board, enabling local signal processing, diagnostics, and communication over the IONet Ethernet network.

The first eight inputs can be configured for ±5V, ±10V, or 0–20mA signals, while the remaining inputs support low-current measurement modes for specialized instrumentation. The outputs deliver 0–20mA signals used for actuator or control device interfacing.

IS220PAICH1B is engineered for mission-critical environments such as gas turbines and steam turbines, where measurement accuracy, fault detection, and system redundancy are essential. It supports auto-reconfiguration, allowing quick replacement without manual recalibration, significantly reducing downtime.
