Allen-Bradley 1746-FIO4V Flex IO Digital Input Output Module

The Allen-Bradley 1746-FIO4V is a Fast Analog I/O module for the SLC 500 Flex I/O backplane, delivering 2 differential analog input channels and 2 voltage output channels in a compact 4-point module. The input channels are differential and can be configured per channel for voltage or current signals, enabling flexible sensing of analog measurements. The two outputs are voltage outputs (not individually isolated) and are intended to drive analog actuators or reference signals in process or automation loops. On the rack, the module draws power from the backplane with a backplane current rating of 120 mA and is identified by ID Code 3218. This 1746-FIO4V is designed for legacy automation setups requiring a small 2-in/2-out analog interface, suitable for tasks such as sensor monitoring and valve or actuator control through analog voltage outputs.
