Allen-Bradley 1746-NO4I Isolated Analog Output Module

The Allen-Bradley 1746-NO4I Isolated Analog Output Module is a four-channel analog output expansion for SLC 500 PLCs, converting digital control signals from the controller into precise isolated analog outputs for field devices. Each channel offers isolation from the backplane and other channels, with output type selectable per channel as voltage or current and support for 0–10 V, ±10 V, 0–20 mA, and 4–20 mA signals at 16-bit resolution. The module plugs into the SLC 500 backplane as a rack-mounted I/O expansion and is used to drive valves, drives, actuators, and other equipment requiring variable analog signals in process control, HVAC, water/wastewater treatment, batching, or manufacturing lines. Operating temperature range is 0°C to 60°C.
