Cooper Bussmann BU-905U-L Wireless I/O Installation Manual

Cooper Bussmann recommends using shielded cable for analog I/O loops to minimize induced noise and Radio Frequency Interference (RFI).

Note: You should only connect one end of the cable shield to Earth

To connect an analog signal from a PLC or DCS output to an analog input on the BU-905U-L-T, you must carefully check the internal circuit of the output as different devices use different ways to create an analog signal.

The following diagrams illustrate different connection methods:
