IS230SNCIH2A | GE Mark VIe Discrete Input I/O Module Pack

Product Description

High-Integrity Discrete Signal Processing

The IS230SNCIH2A (SNCI) functions as a critical interface within the GE Mark VIe distributed control system (DCS). It specifically handles discrete inputs from field devices such as limit switches, relay contacts, and pushbuttons. This module utilizes a Simplex redundancy style, meaning it operates as a single I/O pack that communicates directly with the controller via the internal IONet. The design emphasizes deterministic timing, ensuring that state changes in field equipment are captured and reported within the specific control cycle requirements of steam and gas turbines.

Unlike multi-purpose I/O modules, the IS230SNCIH2A is optimized for high-density discrete monitoring. It converts raw 24 V DC signals into digital data packets that the Mark VIe controller processes for logic execution. The module hardware includes advanced filtering to eliminate contact bounce and electromagnetic interference, providing a clean signal for critical control loops.
