Honeywell 8C-TDIL11 51306858-175 Digital Input Module

Product Introduction

The Honeywell 8C-TDIL11 (Part Number: 51306858-175) is a rugged and high-density digital input module used within Honeywell’s Experion PKS control systems, particularly the C300 controller platform. It is designed to monitor and collect 32 discrete field input signals from on-site devices such as contact switches, safety interlocks, proximity sensors, and other binary output equipment.

Tailored for critical industrial applications, the module operates using a 24V DC nominal signal and offers channel-level isolation to ensure protection and signal integrity across harsh environments. Each input point is clearly monitored through diagnostic features and LED indicators for easy identification of real-time signal states. The 8C-TDIL11 is widely implemented in continuous process industries where operational reliability and signal accuracy are essential.
