About 1746-NI4

The Allen Bradley SLC 500 4-Channel Analog Input Module 1746-NI4 contains 4 user-selectable analog channels for voltage or current to support multiple monitoring and control applications; it has a 16-bit resolution and contains a removable terminal block that provides connections analog input channel. This channel can be connected as a single or differential input. There is a DIP that switches on the circuit board to select the input or current voltage. The Backplane current at 5 Volts of this module is 25 mA; at 24 Volts, the current is 85 mA. Caution should be given to avoid connecting the voltage source without the transmitter current, etc. to the channel configured for current input. Incorrect module operation or module damage may occur.

The 1746-NI4 has Standard Cable Lengths of 0.5, 1, 2.5, and 5.0 meters. The AIFM Connector of this module is 15-pin D-shell. The Allen Bradley 1746-NI4 has Current Loop Input Specifications: the input range is ±20 mA (nominal) and ±30 mA (maximum). The Input impedance is 250 Ohms with a resolution of 1.22070 μA per LSB and an approximate Gain error drift of ±67 ppm/degrees Celsius: the overall accuracy at 25 degrees Celsius is ±0.365% of full scale, and  ±0.642% at 60 degrees Celsius. The overall accuracy drift is +79 ppm/degree Celsius of full scale. The 1746-NI4 also Voltage input Specifications: the input range is ±10 Volts DC -1 LSB. Its impedance is 1 mOhms. The accuracy drift is +63 ppm/ degrees Celsius of full scale. The Resolution is 305.176 μV per LSB, with a Gain error drift at ±57 ppm/degree Celsius. The Overall accuracy at 25 degrees Celsius is ±0.284% of full scale, and ±0.504% at 60 degrees Celsius.

Troubleshooting for 1746-NI4

1746-NI4


 

The 1746-NI4 is a multi-use analog module that provides both voltage and current reading for each individual channel 


Individual card troubleshooting 

  • Ensure the power light on the card comes on when inserted into the rack 

  • Check dip switches to see that you are using the correct setting (current or voltage) for your application

  •  Visually inspect the card outside of the rack: check that resistors, capacitors, TRIACs and chips all look functional 

 

In this demonstration of testing the 1746-NI4 we will be using the following parts 

  • 1746-A7 (Rack)

  • 1747-L553 (processor)

  • 1746-P2 (power supply)

  • Variable voltage DC power supply 


Test Voltage First:

  • Ensure that all dip switches are in the off position (as pictured)

Insert the card into the rack (we will be using slot 5)


 

1. Open a new project in RS-Logix 500 and select the processor that will be used.  


 

2. Go into I/O configuration to read the 1747-NI4 in the back plane 


NOTE: If the wrong processor has been selected from step 1, you will be asked to change the processor type. A window will appear and ask you to correct the problem, select “okay” to do so.

 

3. Download the program to the processor 

4. Once online, go into the input table 

This is where we will read our inputs changing when various voltages are applied  

 




 


 

            INPUT ranges are 

Current: -20mA to +20mA 

Voltage: -10vDC to +10vDC 

 

Terminals for testing:

Positive terminals 

  • 0

  • 3

  • 6

  • 9

Negative terminals: 

  • 1

  • 4

  • 7

  • 10

 


5. Applying 5.33v to terminal 0 and 1 for testing input 1 
    We will get a reading around 17482    +- 100

 


 

6. Continue this process all the way down until input 3 has been reached 



 

Testing with ANL COM 

 

Apply the black lead (negative) to ANL COM

 

Now for each input apply the 5.33v to each positive input terminal 

  • 0
  • 3
  • 6
  • 9

We will get a reading of 8735 +-100

testing current we will follow the same process except this time our dip switches on the side of the card will be in the on position (up instead  of down)




 

 

 

Each input reading will be similar to the last for both voltage and current testing
