Spectrum Controls 1756sc-IF8u Universal Input Module

Spectrum Controls 1756sc-IF8u Universal Input Module is an 8-channel universal analog input card designed for the Allen-Bradley ControlLogix 1756 backplane, delivering universal input capability in a single module that can be installed in any I/O slot and integrated into existing ControlLogix systems for streamlined, one-card sensor interfacing. It uses a sigma-delta analog-to-digital conversion method and a low-pass digital filter with programmable notch frequencies to accommodate a wide range of sensor signals, while each channel is isolation-tested from the backplane and from other channels to minimize cross-channel interference. Open-wire detection is supported to quickly identify wiring faults, and the eight channels provide full universal analog capability within one module, offering a compact alternative to multiple specialist input cards in environments where space and installation simplicity matter. Power and consumption specifications include a backplane current draw up to 230 mA at 5 VDC (75 mA at 24 VDC) and a maximum backplane power of 3.00 W (0.6 W at 5 VDC, 2.4 W at 24 VDC), making it compatible with standard ControlLogix power architectures.
