Product Overview

The CC-UDIR01 (51405040-175) is a high-performance Digital Input Relay Adapter module designed for the Honeywell Experion® PKS C-Series I/O platform. This module serves as a critical interface for acquiring discrete signals from high-voltage field devices—such as circuit breakers, limit switches, and pressure sensors—and converting them into isolated relay inputs. By providing a secure galvanic barrier between field-side voltage (up to 250V AC/DC) and the sensitive control logic of the C300 controller, the CC-UDIR01 ensures maximum system integrity and personnel safety. Its ruggedized design and hot-swappable capability make it a mechanical necessity for mission-critical discrete monitoring in power generation, oil and gas, and heavy manufacturing.
