PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-FIO4V is an SLC 500 analog combination module providing fast mixed I/O capabilities. It incorporates two differential input channels selectable for voltage or current signals. It also provides two voltage output channels grouped together. The module communicates using 16-bit two's complement binary format. Field wiring to backplane electrical isolation is rated at 500V DC.
This fast I/O module supports demanding control loops that require rapid signal conversion. Input resolution is 12 bits and output resolution is 14 bits. Input circuits accommodate 0 to 20 mA or standard voltage signals. The analog voltage outputs deliver up to -10 to +10V DC for modulating control devices. The open-type hardware installs directly into any standard SLC 500 chassis slot.
