Allen-Bradley 1756-IF8I ControlLogix Analog Isolated Input Module

Description

The Allen-Bradley 1756-IF8I ControlLogix Analog Isolated Input Module is a single-slot analog input unit belonging to the ControlLogix programmable automation controller (PAC) series, designed for industrial signal acquisition applications. It features 8 isolated input channels, enabling simultaneous collection of 8 analog signals to meet multi-sensor monitoring needs in complex industrial environments. The module supports configurable input signal types, including +/-10VDC, 0-10VDC, 0-5VDC voltage signals, and 0-20mA current signals, making it compatible with a wide range of analog signal-generating devices such as transmitters, sensors, signal splitters, isolators, and panel meters. Equipped with high-resolution conversion capabilities, it offers resolutions ranging from 15 to 16 bits: for +/-10VDC at +/-10.25V, it provides 320 microvolts per count (15-bit signed bipolar) or 160 microvolts per count (16-bit); for 0-10VDC, it delivers 80 microvolts per count (16-bit); for 0-5VDC and 0-20mA signals, it offers 0.32 microamps per count (16-bit). Additional key features include built-in module filters, under-range/over-range detection, process alarms, and open-circuit detection, which enhance signal processing accuracy and overall system stability and reliability.
