The Allen-Bradley 1746-NO4I is an analog output module in the SLC-500 series. It has four analog output channels with four current outputs which are not isolated on an individual level. The 1746-NO4I draws a maximum backplane current of 55 mA at 5 Volts and 195 mA at 24 Volts. When supplied with an external power of 24 Volts, has +/- 10% current at a maximum of 195 mA; it also has an SW1 switch, making it easier to select the source of power. When the SW1 switch is UP, the 1746-NO4I draws its power from an external source, being powered from the backplane when the SW1 switch is in the DOWN position.
The 1746-NO4I has a resolution of 2.56348A per LSB. At a 0 to 21 mA current range, the 1746-NO4I has 0 to 32767 output words; at 0 to 20 mA it has 0 to 31208 output words, and at 4 to 20 mA it has 6242 to 31208 output words.
The 1746-NO4I has an operating temperature between 0 and 60 degrees Celsius. It has a 14-bit resolution with a 2.5 millisecond step response time. It uses the R-R method of conversion and a 0 to 500Ω load range. In addition, it has a 5% over-range ability. At 25 degrees Celsius, it has an accuracy (overall) of +/- 0.298% full scale; at 0 to 60 degrees Celsius, it has an accuracy of +/- 0.541% its rated +/- 70 ppm/degree Celsius accuracy drift (overall maximum full scale).
The 1746-NO4I has a +/- 298% of full-scale gain error at 25 degrees Celsius and a gain error of +/- 516% of full scale at 0 to 60 degrees Celsius, plus a maximum of +/- 62 ppm/degree Celsius of full scale drift on gain error.

About 1746-NO4I
The 1746-NO4I I/O module is a member of the SLC 500 device series that is manufactured by Allen-Bradley/Rockwell Automation. It is an output module with 4 output channels. It is also analog. All of the outputs on the 1746-NO4I output module are current outputs that are designed to handle all kinds of machine monitoring and control applications. Its maximum backplane current draw ratings are 55 milliamps at 5 Volts and 195 milliamps at 24 Volts. The 1746-NO4I output module cannot be configured with DIP switches because it does not have analog inputs. The only switch that it supports is a 24 Volts DC power selector switch. When the 1746-NO4I output module is installed in the SLC chassis, it should be installed as far away as possible from modules with AC voltage or high levels of DC voltage, as far as possible from the power supply in a modular system, and in the chassis that is closest to the bottom of the SLC enclosure.
The Allen-Bradley/Rockwell Automation 1746-NO4I SLC 500 4-channel analog output module can support operating current ranges of 0 to 21 milliamps, 0 to 20 milliamps, or from 4 to 20 milliamps for different applications. The 1746-NO4I analog output module can be used in an SLC 500 system that contains input devices that use loop power, but it cannot supply the loop power to these input devices because it is analog. Instead, the users must supply the loop power to the input devices by other means. The 1746-NO4I analog output module can be powered by the host SLC 500 controller device’s 24 Volts DC rated power source as long as it is a fixed SLC 500 device.
The Allen-Bradley 1746-NO4I output module is a 4-channel output module from the SLC 500 series. All 4 of its outputs are current outputs that can support different current ranges.
