Available. The Allen-Bradley 1746-NO4I is a 4-channel analog current output module designed for the SLC 500 series programmable logic controllers (PLCs). This module provides precise control over analog outputs, making it ideal for applications requiring accurate current signal transmission. Each channel delivers a current output ranging from 0 to 20 mA, with a full-scale output of 21 mA, ensuring compatibility with a wide range of industrial devices. The module features a 14-bit resolution, allowing for fine-grained control and minimal signal distortion. Its step response time is 2.5 milliseconds, facilitating rapid adjustments in dynamic processes. The 1746-NO4I operates with a backplane current load of 55 mA at 5V and 195 mA at 24V, ensuring efficient power consumption. The module supports a load range of 0 to 500 ohms, accommodating various connected devices. It utilizes the R-2R ladder conversion method for signal processing, ensuring high accuracy and reliability. The module is housed in an open chassis mount, measuring 59 mm in height, 168 mm in width, and 252 mm in length, with a weight of 0.32 kg, facilitating easy integration into existing systems. Please note that as of April 29, 2021, the 1746-NO4I has been discontinued and is no longer available for sale. Customers are encouraged to explore alternative solutions within the Allen-Bradley product line for their automation needs.
