      Product Information:

      The Allen-Bradley 1756-IA16I is a ControlLogix 16-point isolated AC input module. It is designed to connect standard AC field signals (such as limit switches, pushbuttons, and motor starter contacts) to Allen-Bradley ControlLogix PAC (Programmable Automation Controller) systems. A key feature of this module is its point-to-point isolation, ensuring that each input channel is electrically isolated from other channels.

      The 1756-IA16I operates from 79 to 132V AC and from 47 to 63 Hz. This module can be installed directly into a 1756 local or remote chassis.

      Features:

      • ControlLogix 16-point Isolated AC Input Module
      • 74V AC to 132V AC (nominal 120V AC) at a frequency of 47 Hz to 63 Hz
      • This module has Sixteen (16) individually isolated channels
      The Allen-Bradley 1756-IA16 is a ControlLogix I/O module. This isolated AC digital input module features a display showing input and communication status, as well as module operating conditions. Each input channel is independently isolated, with a rated continuous input voltage of 125 volts per channel. The module can be directly connected to a ControlLogix chassis. Compatible removable terminal block housings are the 1756-TBCH and 1756-TBS6H.

      This module can be installed in a local or remote I/O ControlLogix chassis. A local ControlLogix chassis refers to the component with a ControlLogix processor installed, while a remote I/O chassis refers to a ControlLogix chassis that communicates with the local chassis via a communication adapter.

      The 1756-IA16I Allen Bradley Digital AC Input Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      Allen Bradley 1756-IA16I Digital AC Input Module Manuals(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
      Because this module features point-to-point isolation (250V continuous rated voltage between channels), it is ideal for harsh industrial environments:
      Multiple power supplies: It allows you to connect field inputs from completely different phases, transformers, or external control panels to a single module without short circuits.
      Ground loop protection: Electrical noise or grounding faults on one field device will not propagate and affect signals in adjacent channels.
      This module can be installed in any standard 1756 ControlLogix chassis slot.
      It requires separate purchase of removable terminal blocks (RTBs) for field wiring:
      1756-TBCH: 36-pin cage-clamp RTB.
      1756-TBS6H: 36-pin spring-clamp RTB.
