General Electric IS220PAICH2A Mark VIe Analog I/O Module

Description

The IS220PAICH2A functions as a distributed electrical interface designed to bridge one or two I/O Ethernet networks with an analog input terminal board. This Analog I/O Pack is engineered for the Mark VIe Turbine Control System, providing precise data acquisition and processing capabilities across various compatible terminal boards. Internally, the unit consists of a standard BPPB processor board combined with an acquisition board dedicated exclusively to analog input signaling. The IS220PAICH2A distributed I/O pack accommodates up to 10 analog inputs with versatile voltage and current loop configurations to monitor field sensors in critical utility turbine operations.

Features

• Dual-board architecture containing a specialized analog acquisition board and a standard BPPB processor board.
• Supports up to 10 analog inputs with configurable hardware sub-groupings.
• Configurable input ranges covering voltage (+/- 5V or 10V) and current loops (0-20 mA or +/- 1 mA).
• Integrated local diagnostic capabilities via a front-facing infrared serial communication port.
• Sprayed conformal coating applied to the base circuitry for enhanced protection against industrial contaminants.
• Local status visibility provided by built-in hardware LED indicators for power, attention, and link states.

Applications

• Gas and steam turbine control networks
• Industrial analog sensor data acquisition
• Distributed I/O processing in Mark VIe control loops
• Current loop and voltage-based process monitoring

Installation Guidelines

• Network Integration: Attach the primary and secondary network links using standard RJ45 Ethernet cables to establish redundancy across the designated I/O networks.
• Terminal Board Alignment: Securely mate the DC 37-pin connector to the matching interface on the analog input terminal board, ensuring the pins align straight to avoid damage.
• Power Connection: Verify proper voltage and grounding polarity before inserting the 3-pin power connector into the pack.
• Environmental Handling: Maintain handling standards suitable for conformally coated Group 2 components. Avoid scratching the sprayed protective layer during mechanical installation.
