Hello All,

This is a basic question on wiring VADT150-42-24 to Click PLC Analog 4-20mA module. CO-4AD2DA-1 module has a positive(CH1) and a negative(0V) and power pins to power the module (24V and 0V). Internally the power(0V) and negative (0V) of the channel are connected.

VADT150-42-24 has six pins. 2 for taking voltage input (5,6), 2 for output(1,2) and 2 for power(3,3). I understand that Output pins (1,2) will be connected to CH1 and 0V. But I am not sure how to connect the power for the VADT. Which of the pins should have 24VDC and GND between 3 & 4. Any help appreciated.

I have attached an image as well. Thanks.
