Product Overview

The Honeywell 8C-TDIL01, identified by part number 51306856-175, is a high-performance discrete input interface designed for the Experion PKS Series 8 I/O hardware platform. This module serves as a critical data acquisition point, capturing 24VDC binary signals from field-mounted devices and transmitting them to the C300 controller. Engineered for high-density environments, the 8C-TDIL01 features a vertical "inline" design that optimizes cabinet rail space while providing robust galvanic isolation. It is specifically built to handle the rigorous timing requirements of modern Distributed Control Systems (DCS), ensuring that state changes from switches, relays, and sensors are recorded with millisecond precision and zero signal bounce.
