Allen Bradley 1756-IF16IH ControlLogix 16-Channel HART Isolated Analog Input Module

Product Overview

The Allen Bradley 1756-IF16IH functions as a high-density, high-performance analog input solution within the ControlLogix® platform. This module provides 16 individually isolated channels and integrates HART (Highway Addressable Remote Transducer) data directly into the ControlLogix backplane. It allows users to capture sophisticated diagnostic data from "smart" field devices without requiring external hardware. We supply this unit as 100% brand new and original, ensuring maximum signal fidelity and system uptime for your critical process loops.

Technical Specifications

The 1756-IF16IH combines individual channel isolation with high-resolution data conversion:

Engineering Advantages

• Individual Channel Isolation: The 1756-IF16IH features point-to-point electrical isolation. This architecture prevents ground loops and ensures that an electrical fault on one field device does not compromise the signal integrity of the remaining 15 channels.

• Integrated HART Diagnostics: The module acts as a HART modem for every channel. It passes secondary variables and device health status directly to the controller, enabling predictive maintenance strategies and remote instrument calibration via FactoryTalk® AssetCentre.

• High-Density Monitoring: Providing 16 isolated channels in a single slot maximizes chassis space. This density reduces the number of I/O racks required for large-scale operations, lowering total system footprint and hardware costs.

• Simplified Field Calibration: The 16-bit resolution provides extreme precision for sensitive process variables. This eliminates the need for frequent manual recalibration of the input loops, as the module maintains stable performance across varying industrial temperatures.

• Hot-Swappable Design: Like all ControlLogix I/O, the 1756-IF16IH supports Removal and Insertion Under Power (RIUP). Maintenance teams can replace the module without shutting down the entire chassis, significantly reducing planned downtime.

FAQs

• Does the 1756-IF16IH support voltage inputs?

  No. This module specifically optimizes for 4–20 mA current loops. If your application requires voltage inputs (0–10V), you should evaluate the 1756-IF16 or 1756-IF16V modules.

• Is this a genuine, factory-sealed Allen Bradley original?

  Absolutely. We ship only 100% brand new 1756-IF16IH units in their original manufacturer packaging. Every module undergoes factory testing and arrives with a verified serial number for E-E-A-T procurement compliance.

• Which Removable Terminal Block (RTB) does this module require?

  The module requires either the 1756-TBCH (36-pin Screw Clamp) or the 1756-TBSH (36-pin Spring Clamp) RTB. Please note that RTBs are sold separately and are essential for module operation.

• Can I access HART data through the PLC ladder logic?

  Yes. The ControlLogix processor receives HART data as part of the module’s input image. You can use instruction sets to read device status, manufacturer IDs, and secondary process variables directly within Studio 5000®.
