CC-TCNT01 | Honeywell | C300 16-Channel TC Input Card

Product Overview

The Honeywell CC-TCNT01 (Part Number 51308307-175) is a high-precision Thermocouple Analog Input Module engineered for the Experion PKS Series C platform. This module serves as the primary interface for capturing millivolt signals from field-mounted thermocouples and converting them into high-resolution digital data for the C300 controller. Designed for mission-critical temperature monitoring in furnaces, reactors, and boilers, the CC-TCNT01 delivers the accuracy and thermal stability required for complex process loops. We provide this module as 100% Brand New original equipment, ensuring maximum authority and reliability for your DCS infrastructure.

Technical Specifications

Engineering Advantages

• Universal Thermocouple Compatibility: The CC-TCNT01 supports a wide array of IEC-standard thermocouple types (J, K, T, E, R, S, B, N). This flexibility allows engineers to standardize on a single module type across the entire plant, significantly reducing spare parts inventory.

• Automatic Cold Junction Compensation (CJC): The module incorporates precision CJC at the terminal level. This eliminates the need for external compensation hardware and ensures highly accurate temperature readings even as ambient cabinet temperatures fluctuate.

• Superior Noise Immunity: High-grade galvanic isolation protects each of the 16 channels. This prevents ground loops and electromagnetic interference (EMI)—common in high-voltage turbine or furnace environments—from corrupting sensitive process data.

• Intelligent Diagnostics: The 51308307-175 hardware continuously monitors loop integrity. It detects open circuits (sensor burnout) and signal anomalies instantly, allowing the Experion PKS system to trigger safe state logic or maintenance alerts before a process trip occurs.

FAQs

• Can the CC-TCNT01 monitor millivolt (mV) signals directly?

  Yes. In addition to standard thermocouple curves, the module handles low-level millivolt inputs, making it suitable for specialized sensors that utilize mV outputs.

• Does this module require a specific I/O Termination Assembly (IOTA)?

  Yes, the CC-TCNT01 must be paired with a compatible Series C IOTA. The IOTA provides the physical connection points for the thermocouple lead wires and houses the CJC sensors.

• How does the G3 conformal coating on the -175 variant help?

  The 51308307-175 features G3-level conformal coating, which safeguards the Printed Wiring Assembly (PWA) against corrosive gases (like $H_2S$ or $Cl_2$) and high humidity, which is essential for refinery and offshore applications.
