About 1746-NIO4V

The 1746-NIO4V SLC 500 Analog Combination I/O Module by Allen-Bradley is an I/O module installed on the 1746 Chassis that has 2 user-selectable (per channel) current or voltage inputs and 2 voltage outputs. It has 2 current-loop inputs with a normal rating of -20 to 20mA at a 250 Ohm impedance and an input accuracy of +/- 0.642% at a drift rate of 79 ppm/5 degrees Celsius. Its two input points also have voltage ratings of -10 to 10 Volts DC with an impedance of 1M Ohm and a 10 Volt DC full-scale resolution of 305.176 ? V per LSB.

The voltage inputs have an accuracy of +/-0.504%, an overall drift accuracy of +/- 63 ppm/degree Celsius, and a maximum gain error of +/- 0.461%. The inputs have an offset error of +/- 14 LSB at 0 to 60 degrees Celsius, and the 1746-NIO4V maximum overvoltage protection across the input terminals comes in at either 220 Volts AC or 220 Volts DC. It uses the R-2R Ladder Digital-to-Analog Converter (DAC) with a converter resolution of 14 bits at its voltage output and a response time of 2 milliseconds. The output has a load range greater than 1KOhms with a load reactance of 1? F and an overall output range of -10 to 10 Volts. The voltage has an overall accuracy of +/- 0.384% of a 10 Volt DC full-scale voltage and a maximum drift accuracy of +/- 54 ppm per degree Celsius. The 1746-NIO4V also has a maximum gain error of +/- 0.374% with a drift error of ±47 ppm/ degree Celsius and an output offset error of +/-11 LSB. The 1746-NIO4V offers Field Wiring-to-Backplane Isolation at 500 Volts DC and uses the Shielded Belden #8761 recommended cable with a rated 14 AWG size.

The Allen-Bradley 1746-NIO4V is an analog I/O combination module. This module features Two (2) input channels and Two (2) output channels. The input channels features compatibility with differential voltage and current inputs that are individually configurable. For current input configuration, accepted signal range is -20 to +20 mA with a resolution of 16-bit with repeatability of ±1 LSB and non-linearity of 0.01%. It uses Delta-Signa modulation conversion method. When configured for voltage input, the accepted voltage signal range is -10 to +10V dc - 1 LSB with resolution of 305.176 µV per LSB.

The output channels of the 1746-NIO4V does not come with isolation. It can provide an output current range of 0-20 mA with resolution of 14-bit, using R-2R Ladder conversion method. It has a step response of 2.5 ms (at 95%).

This combination I/O module has a backplane current draw of 55 mA at 5.1 VDC and 145 mA at 24VDC. It occupies single slot of the chassis and comes with a removable terminal block for terminating signal wires to and from the module.

Additionally, the 1746-NIO4V may become part of the CompactLogix and ControlLogix Programmable Automation Controllers (PAC), acting as a distributed I/O module.

Troubleshooting for 1746-NIO4V

Basic Troubleshooting

Before we get into testing proper, it’s handy to do a quick check to eliminate some possible causes.

  • Visually inspect the card: are there burnt, cracked or broken spots?
  • Check Dip switches 
  • Check the pins which connect to the backplane: Are they properly aligned and in good condition?
  • Check to make sure no other components are obviously compromised.

Testing Inputs

  • Plug module into rack and read I/O to see that it is seen in the backplane
  • Go online with the processor
  • Go into input table 
  • Apply +5v or -5v for current selection or +10v to -10v for voltage selection 

We will be using the current selection in this example 

  • Apply positive lead to IN 0+ 
  • Apply negative lead to IN 0-
  • With 3.11 v we read (10179)

\\\\\\\"\\\\\\\"

Do this same process again for IN 1


Testing Outputs

  • Go into output table 
  • Find the 2 outputs associated with the card 
  • Read the voltage  of (OUT 0) with 0 in the channel or all bits set to 0

\\\\\\\"\\\\\\\"

Our meter will read 0 or a voltage very close to zero

\\\\\\\"\\\\\\\"

Now let’s change the words status to 32767 or put a 1 in for all 16 bits. The reading on our voltmeter should be 9.98 9.9 or 10v exactly.

\\\\\\\"\\\\\\\"


If this happens for both channels then the card is good.

Reviews for 1746-NIO4V

General Rating

"Current or voltage selection available for input channels as well as updating speeds a quick as 512 microseconds with a minimum of two inputs and two outputs that makes the combination suitable for almost any analog situation. " -DO Supply Tech

I/O Rating

"The lowest amount of I/O offered. Depending on the application, this could still be the perfect amount. " -DO Supply Tech

Speed Rating

"The module with the absolute quickest updating speeds. " -DO Supply Tech

Internal Review

"The 1746-NIO4V is a combination I/O module used for the SLC500 PLC family. This is a cost effective module as it houses both I/O types and capable of interfacing voltage and current inputs and providing current output signals. Compared to dedicated input modules, this module has lesser output channels however, provides flexibility and saves cost especially for smaller systems with limited expansion capability.
