Allen Bradley 1756-IT16 ControlLogix 16-Channel Thermocouple Input Module

Product Overview

The Allen Bradley 1756-IT16 functions as a high-density, non-isolated thermocouple input module specifically engineered for the ControlLogix platform. It provides 16 independent channels to interface with various thermocouple types and millivolt signals, converting low-level analog data into high-resolution digital values for the controller. This module excels in temperature-sensitive applications where rack space efficiency and extreme precision are critical. We offer this unit as 100% Brand New, ensuring it meets all original manufacturer performance benchmarks.

Technical Specifications

Engineering Advantages

• High-Density Thermal Mapping: The 16-channel architecture allows engineers to monitor large-scale temperature arrays using a single chassis slot. This density reduces the overall hardware footprint and minimizes the need for additional expansion racks.

• Precision Signal Conversion: The module utilizes 24-bit resolution to detect minute temperature fluctuations. This ultra-fine granularity ensures superior control loop stability in critical processes like plastic extrusion, furnace control, and pharmaceutical batching.

• Integrated Diagnostics: A dedicated status LED provides real-time visual feedback on module health and channel status. This feature accelerates on-site troubleshooting by immediately identifying fault conditions without requiring a laptop connection.

• Enhanced EMI Resistance: Advanced filtering circuitry within the 1756-IT16 rejects common-mode noise and electromagnetic interference typical of heavy industrial environments. This ensures that the low-millivolt signals from thermocouples remain accurate and stable.

FAQs

• Is this 1756-IT16 module a brand-new original product?

  Yes. We guarantee this unit is 100% Brand New and ships in its original factory packaging. It has never been installed or refurbished, ensuring maximum reliability for your critical systems.

• Does the 1756-IT16 support Cold Junction Compensation (CJC)?

  Yes. Proper temperature measurement requires an accurate cold junction reference. This module integrates with the specific Removable Terminal Block (RTB) sensors to maintain measurement accuracy across the entire operating temperature range.

• Can I use this module for standard voltage inputs?

  The module specifically targets thermocouple and millivolt applications (-100 to +100 mV). While it excels at these low-level signals, you should use a standard 1756 analog input module for higher voltage ranges (e.g., 0-10V or 4-20mA).

• Which Removable Terminal Block (RTB) do I need for this module?

  The 1756-IT16 requires a 36-pin RTB, typically the 1756-TBNH or 1756-TBSH. Always verify that your chosen RTB includes the necessary CJC sensors for thermocouple applications.
