Allen-Bradley 1746-NIO4I High Resolution Analog I/O Module

Allen-Bradley 1746-NIO4I is a SLC 500 high-resolution analog I/O module that provides two differential analog input channels and two analog current output channels in a single 1746-slot module. Each input channel is differential and configurable per channel for either -10 to +10 V DC or -20 to +20 mA, enabling precise sensing from a variety of transducers and sensors; note that the two inputs are not individually isolated. The two outputs are analog current outputs with a 0–20 mA range, suitable for driving current loops or actuators in analog control schemes. The module is designed for use with the SLC 500 backplane and is offered in an open-chassis mount configuration for compact installations in legacy control systems where space is at a premium.
