Description:

The 24-Bit resolution of the Allen-Bradley 1756-IF8I provides an actual resolution of 1.49 ?V/count for +/- 10.5 VDC, 0 - 10.5VDC and 0-5.25 VDC for Voltage input while for Current input, the actual resolution for 0-21 mA signal is 2.99 nA/count. This resolution is not the standard resolution of any analog module as typical resolution of standard analog input are 13-16 Bit resolutions only.

The terminated Analog signals enables interface to actual process variables. This is necessary for the Programmable Logic Controller (PLC) to monitor or control a process by allowing integration to computer based control systems, such as a Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA) and Distributed Control Systems (DCS).

This module is installed to any ControlLogix chassis whether local, distributed or remote I/O installation. It requires 1756-TBCH and 1756-TBS6H Removable Terminal Blocks for signal wiring and appropriate wire size range for this module is 0.33 to 2.1 mm2 (22 to 14 AWG) solid or stranded shielded copper wire.

The Allen-Bradley 1756-IF8I is an Eight (8) Point General-Purpose Isolated Analog Current/Voltage Input Module. It requires a 36-pin Removable Terminal Block (RTB) before it can be wired with input signals. The 1756-IF8I provides higher-level accuracy through its 24-Bit conversion resolution and supports 2-wire or 40Wire transmitter configuration.
