1746-NO4I Allen Bradley SLC 4 Point Analog Output Module
The Allen-Bradley 1746-NO4I module is a Programmable Logic Controller (PLC) analog output module that belongs to the SLC 500 product platform. This module is used with the mentioned platform and compatible with the Two (2) controller variant such as fixed hardware of modular hardware style.
The Allen-Bradley 1746-NO4I is an SLC 500 Four (4) channel analog output module using a 16-bit 2’s complementary binary format. It has 4 current outputs that have an output range of 0 to +20 mA with full-scale current output of 21 mA. The backplane current draw of this module is 55 mA at 5 VDC while and 195 mA at 24 VDC while the over range capacity is 5% (0 to 21 mA and 1 LSB). Its power supply voltage rating is 24 Volts DC +/- 10% at 195 mA maximum and the backplane isolation is 500 Volts DC. Note that some applications require 21.6 to 26.4 Volts DC power when there is not enough power flowing from the SLC power supply.
The 1746-NO4I also comes with an update response time of 512 µs for all the channels that are in parallel. The input step response of this module is 2.5 milliseconds at 95%. Its operating temperature is 0 to 60 degrees Celsius; Storage temperature is -40 to 85 degrees Celsius, and its non-condensing ambient relative humidity is 5 to 95%. This factory-calibrated output module has an open enclosure and it is only compatible with the 1746 chassis. An LED status indicator is also present in this module. The 1746-NO4I has a load range of 0 to 500 ohms and maximum load reactance of 100 µH, with a converter resolution of 14 bits via the R-2R Ladder conversion method. The 1746-NO4I’s maximum overall accuracy drift is +/- 70 ppm/ degree Celsius of the full-scale accuracy.
