PLC Outputs
Type How to Wire Notes
Relays / Sink type transistors
Source type transistors Values may be inverted when using a PLC with source type outputs.
Fix this by inverting the actuators in the Driver Window for the board in use.

Resistors: We suggest values between 1 KΩ and 4.7 KΩ with a power rating of 0.5 W.

Resistors: We suggest values between 1 KΩ and 4.7 KΩ with a power rating of 0.5 W.

The DAQ board supports input voltages from 5 V to 50 V, and output voltages from 5 V to 40 V. If you are not sure how to properly wire the device, consult the Advantech manual.

Allen-Bradley SLC500

Allen-Bradley SLC500 and Advantech USB-4750 DAQ board.

We suggest values between 1 KΩ and 4.7 KΩ with a power rating of 0.5W for the resistor values RA and RB.

The following steps show how to find the appropriate resistors values (RA) for the PLC outputs

  1. Start by using resistors with the highest possible value (4.7 KΩ)
  2. Force a PLC output and check if the application detects it
  3. If the application detects the forced value, you found the correct resistor, otherwise choose a lower resistor value and repeat the process
  4. Repeat these steps for all outputs

  1. Start using resistors with the highest possible value (4.7 KΩ)
  2. Force a sensor value on the application and check if PLC input detects it
  3. If the PLC input detects the forced value, you found the correct resistor, otherwise choose a lower resistor value and repeat the process
  4. Repeat these steps for all inputs
