Allen-Bradley|1746-NO4I| 4-channel analog output module
Description
The Allen Bradley 1746-NO4I is a 4-channel analog output module designed for the SLC 500 system, providing current outputs for industrial control applications. It supports precise signal conversion and flexible configuration options.
Features
- 4 Current Outputs: Supports 4 channels of current output (0…21 mA or 4…20 mA).
- External Power Option: Can use an external 24V DC power supply.
- DIP Switch Configuration: Allows easy setup for different current ranges.
- High Precision: Converts 16-bit integer values to accurate current signals.
Technical Specifications
General Specifications
- Model Number: 1746-NO4I
- Output Channels: 4 current outputs, not individually isolated
