PRODUCT INFORMATION
Product Overview
The General Electric IS220PAICH1A is an Analog I/O Pack designed for Mark VI and Mark VIe turbine control platforms. This unit mounts within thirteen-slot or twenty-one-slot VME rack assemblies. It operates in gas, steam, and wind turbine management systems. The pack features conformal coating across the circuit board to protect against harsh industrial environments. It supports both simplex configurations and Triple Modular Redundant control architectures. In redundant setups, each pack interfaces with separate control modules and I/O networks.
The front panel of the IS220PAICH1A provides four diagnostic status indicators. One dedicated I/O connector sits at the bottom of the module housing. Nominal power supply input is 28.0 VDC with a direct current draw of 0.49 A at 28.6 VDC. The minimum operational voltage is 27.4 VDC. This module interfaces directly with compatible input-output terminal boards including the IS200STAIH1A, IS200STAIH2A, and IS20TBAIH1C. It is rated for deployment in both non-hazardous and hazardous industrial areas.
