Product Overview

The Honeywell CC-TDIL01 (PN: 51308386-175) is a 32-channel Digital Input IOTA for Experion PKS Series C. It provides a non-redundant, high-density interface for capturing discrete 24 VDC signals from field devices such as limit switches, pushbuttons, and interlock contacts.

The module offers flexible power options (internal system supply or external field excitation), integrated short-circuit protection, and industrial-grade electrical isolation, ensuring reliable operation even in harsh environments.

Technical Data

Key Features:

• Selective Field Powering: Jumper-selectable internal or external 24 V supply.

• SOE Support: High-resolution (1 ms) timestamping for sequence-of-events analysis.

• Fault Isolation: Short circuit on one input does not affect other channels.

• Hazardous Area Certified: Class I, Division 2 / Zone 2; non-incendive field power.

Typical Applications

• Valve Position Monitoring: Open/closed status for automated valves in refineries/chemical plants.

• Safety Interlocking: Emergency stops, pull-cord switches.

• Motor Status Tracking: Run/stop and fault signals from MCCs.

• Utilities Management: Level and pressure switch monitoring in water/power plants.

FAQ

Q1: Can this module be used for redundant DI configuration?
A1: No. CC-TDIL01 is non-redundant; use CC-TDIL11 for redundant dual-module setups.

Q2: Difference between CC-TDIL01 and CC-TDIL01-51308386-175?
A2: 51308386-175 confirms G3 conformal coating for harsh environments; functionally the same module.

Q3: Does it support 48 V DC signals?
A3: No, designed for 24 V DC. Verify module/IOTA rating before connecting 48 V signals.

Q4: How to detect a broken field wire?
A4: Supports Open Wire Detection with compatible Series C DI modules, configurable in Experion software.
