PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-NIO4V 1746-N104V is an SLC 500 High Resolution Analog Input/Output Module. It mounts into a single slot of any standard 1746 I/O chassis. The unit provides two differential analog inputs and two analog voltage outputs.
Each input channel supports user-selectable voltage or current measurement ranges. The module delivers fast conversion with an update time of 512 microseconds across all channels. Field wiring connects via a removable terminal block and provides 500V DC isolation to the backplane.
