Allen-Bradley 1746-NIO4V SLC 500 High Resolution Combination Module

Description

The Allen-Bradley 1746-NIO4V SLC 500 High Resolution Combination Module is an analog input/output (I/O) module designed exclusively for the SLC 500 series PLC platform. It features a total of 4 channels, with 2 configurable analog input channels (supporting either voltage or current) and 2 analog voltage output channels. The voltage input and output ranges are both ±10V DC, while current inputs support -20 to 20mA at 250 ohms impedance. With 16-bit high resolution, the module delivers precise signal processing: voltage inputs offer +/-0.504% accuracy with 1M ohms impedance, and current inputs provide +/-0.642% accuracy with a drift rate of 79 ppm per 5 degrees Celsius. Key features include integrated combination I/O functionality that saves panel space, flexible channel configuration to match specific application needs, and a modular design for easy installation and maintenance. It operates in temperatures from 0 to 55 degrees Celsius, with a storage temperature range of -40 to 85 degrees Celsius, and carries UL, CSA, CE, and RoHS certifications. Ideal for small to mid-sized industrial automation systems, it handles simultaneous analog signal acquisition and output, supporting applications like process control, and offers optional HART protocol compatibility for direct connection to HART field devices, eliminating the need for additional multiplexers.
