Allen-Bradley 1746-FIO4V Fast Analog IO Module

Allen-Bradley 1746-FIO4V is a SLC 500 fast analog I/O module that provides two differential input channels (configurable per channel as voltage or current input) and two voltage-output channels, delivering a compact two-in/two-out analog interface for high-speed signaling in mid-range control systems. The inputs are differential and per-channel selectable, enabling direct interfacing to sensors and transducers; the outputs are voltage-type and not individually isolated, suitable for driving analog actuators or valves. This module is designed for use with the 1746 backplane in SLC 500 racks and is documented alongside the 1746-FIO4I as part of Rockwell Automation's Fast Analog I/O family. It operates within a 0 to 60 C ambient temperature range. The catalog number is 1746-FIO4V, confirming its two-in/two-out fast analog I/O configuration in the AB 1746 family. Backplane current draw is 55 mA at 5 V and 120 mA at 24 V.
