Functional Description

IS230SNCIH4A is a Digital Input DIN-Rail Module developed by GE. It is part of the GE Speedtronic Mark VIe gas turbine control system. This module functions on collecting and transmitting discrete input signals from field devices to the control system, enabling accurate monitoring and responsive turbine operations.

Features

The module serves as the electrical interface between one or two I/O Ethernet networks and a discrete input terminal board. It is designed with two main internal components:

• Processor Board: A standard component used across all Mark VIe distributed I/O packs, handling Ethernet communication and processing functions.
• Acquisition Board: Specifically tailored for the discrete input function, responsible for sensing and acquiring digital signals from field devices.

Connectivity and Signal Interface

• Network Communication: The module supports dual RJ45 Ethernet connectors, enabling redundant network paths and ensuring high system availability.
• Power Supply: It features a 3-pin power input to support reliable module operation.
• Input Signal Interface: The discrete signal input is received through a DC-37 pin connector, which directly interfaces with the terminal board, providing a streamlined and secure connection.
• Voltage Sensing: The isolated discrete input board includes voltage sensing capabilities, enhancing accuracy and noise immunity in signal detection.

Diagnostics and Monitoring

• LED Indicators: Provide real-time visual status for power, communication, and signal activity.
• Infrared Port: Allows for local diagnostic communication via a serial interface, facilitating quick field diagnostics without disassembly.
