Product Overview

The Honeywell TC-IDK161 is a 16-channel 24VDC digital input module designed for the Experion Series-C (C300) control system. It monitors discrete field signals from devices such as dry contacts, limit switches, and proximity sensors, converting them into digital data for the controller backplane. This enables accurate real-time status monitoring for process control, sequencing, and safety interlocking applications.

Technical Specifications

Engineering Advantages

• High-Density Series-C Design
  Slim vertical form factor enables dense I/O installation, maximizing the number of input points within a compact control cabinet footprint.

• Robust Noise Immunity
  Built-in opto-isolation protects the controller from electrical noise, surges, and ground disturbances common in industrial environments.

• Fast Multi-Channel Scanning
  Simultaneous high-speed scanning across all 16 channels ensures timely detection of rapid state changes, supporting critical control and safety logic.

• IOTA-Based Maintenance Simplicity
  Uses a separate Input/Output Termination Assembly, allowing the module to be replaced without rewiring field connections, reducing maintenance time.

• Low Thermal Output
  Efficient 24VDC operation results in minimal heat generation, supporting high-density deployments without additional cooling requirements.

FAQs

Is this TC-IDK161 a brand new original part?
Yes, it is supplied as 100% brand new, original Honeywell hardware in factory-sealed packaging.

Which IOTA is compatible with this module?
It typically works with Series-C digital input IOTAs such as CC-TDID11 or CC-TDID01, depending on system configuration and redundancy needs.

Can this module handle AC input signals?
No, it is designed exclusively for 24VDC inputs. Applying AC voltage will damage the module.

Does it support event timestamping?
Yes, when used within Experion PKS, it supports Sequence of Events (SOE) with high-resolution timestamping for critical signal changes.
