GE IS220PAICH2A Analog I/O Module for Mark VI Turbine Control

The GE IS220PAICH2A is an Analog I/O Module, a key component of GE's Mark VIe Speedtronic control system, designed as a direct electrical interface between analog field devices and control networks. It connects to terminal boards via a DC-37 pin connector, supporting both simplex operation with one I/O pack and TMR-capable setups using terminal boards with three DC-37 connectors. Equipped with a BPPx processor and dedicated acquisition board, it facilitates data exchange between analog sensors/actuators and controllers via dual RJ-45 Ethernet ports, with power supplied through a three-pin connector. LED indicators provide visual diagnostic feedback for easy monitoring.

• Analog I/O Flexibility: Offers 10 analog inputs and 2 current outputs.
• Direct Terminal Integration: Connects to simplex or TMR terminal boards via DC-37 pin connectors, with load resistors for current loops located on the terminal board for accurate sensing.
• Dual Ethernet Connectivity: Uses dual RJ-45 ports for redundant communication with controllers, enhancing network reliability; supports connection to R controller networks.
• Easy Installation: Mounts directly to terminal boards with threaded studs, minimizing mechanical stress on connectors; features soft-start capability for safe hot-plugging without power disconnection.
• Enhanced Output Capability: Includes an add-on daughterboard enabling 0-200mA output on the first channel, with variable voltage power to reduce transistor power dissipation.
• Diagnostic Support: LED indicators provide real-time status updates, aiding quick troubleshooting and system maintenance.
