PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-NIO4V is an SLC 500 analog combination module. It installs into a single slot of a 1746 chassis. The module provides two differential inputs and two voltage outputs. Each input channel is individually configurable for voltage or current signals. The module supports SLC 500 systems and distributed architectures in ControlLogix or CompactLogix systems.
Input channels accept -20 to 20 mA current loops or -10 to +10V DC signals. Inputs utilize Delta-Sigma modulation with 16-bit resolution. The two voltage outputs supply -10 to +10V DC using an R-2R ladder converter with 14-bit resolution. Field connections wire directly to an included removable terminal block. Backplane isolation is rated at 500 Volts DC.
