General Electric IS220PAICH1A Mark VIe Analog I/O Pack

Description

The IS220PAICH1A is an analog I/O pack manufactured by General Electric Company USA (GE Industrial Systems) as part of the Mark VIe Series for turbine control and automated drive management systems. This pack interfaces directly with compatible terminal boards to handle dual-way analog input and output signal transitions. It supports specialized control configurations for gas, steam, and alternative energy wind turbine assemblies. Designed for installation inside 13-slot or 21-slot VME racks, the IS220PAICH1A typically operates within a Triple Modular Redundant (TMR) control architecture consisting of individual control modules, dedicated internal I/O nets, and central processor cards. The module integrates a conformal protective circuit coating to withstand aggressive industrial environments and features four front-facing status indicators paired with a base-mounted I/O port.

Installation Guidelines

• Rack Deployment: Install the I/O pack within its designated location inside a compatible 13-slot or 21-slot VME rack assembly.
• Terminal Board Mating: Ensure correct structural connection with approved input-output terminal boards, including the TBAI (such as IS20TBAIH1C) or STAI (such as IS200STAIH1A and IS200STAIH2A) options.
• Power Supply Integrity: Provide a direct current supply source within the critical boundaries of 27.4 VDC minimum and 28.6 VDC maximum, targeting a nominal voltage of 28.0 VDC.
• TMR Setup Requirements: Align network cables and node addresses to sync properly with the independent control modules and individual I/O nets forming the Triple Modular Redundant loop.
