Allen-Bradley 1746-NO4I PLC Analog Ouput Module 1746NO4I

Description:

The Allen-Bradley 1746-NO4I is an analog output module for the SLC 500 series programmable logic controllers. It provides four isolated current output channels, allowing the controller to send analog signals to devices such as control valves, drives, or analog meters. The module is designed for precision and reliability in industrial automation applications requiring accurate analog control. Each channel operates independently, and the module supports various current ranges with built-in diagnostic features.
