Available. The Allen-Bradley 1746-NIO4I is a high-resolution analog input/output module designed for the SLC 500 series programmable logic controllers (PLCs). This module features two differential analog inputs and two analog current outputs, facilitating precise control and monitoring in industrial automation systems. The input channels support voltage signals ranging from ±10V DC or current signals from ±20mA, while the output channels provide a current range of 0 to 20mA. With a resolution of 16 bits for inputs and 14 bits for outputs, the 1746-NIO4I ensures accurate data processing. The module operates within a temperature range of 0°C to 60°C (32°F to 140°F) and requires a backplane current draw of 55mA at 5V DC. It is designed for chassis mounting and is compatible with the SLC 500 modular I/O system, making it suitable for applications requiring reliable analog signal processing and control.
