Product Overview

The Honeywell CC-TDI110 is a high-density discrete input interface engineered for the Experion Process Knowledge System (PKS) Series-C I/O architecture. This 32-channel module acts as a specialized bridge between high-voltage field instrumentation and the C300 control environment. It is specifically designed to sense the state of dry contacts, limit switches, and relay outputs, translating these physical on/off signals into deterministic data for process logic execution and safety interlocking.

By utilizing a vertical mounting profile, the CC-TDI110 optimizes cabinet space while providing superior electrical isolation. Its design eliminates the need for external interposing relays or secondary marshalling for many high-voltage applications, allowing for a more streamlined and reliable control cabinet footprint.
