Wiring Drawing

Note: The circuit board needs to be modified accordingly.

1. If current input is selected, short the shorting cap of the corresponding channel to the left and center pins.
2. If voltage input is selected, short the corresponding number of shorting caps to the right side and the two center pins.

Tips: How to configure RS485 to 4-20mA/0-5V/0-10V output?

Configuring RS485 to analog signal outputs needs to be done through a software or hardware interface. Most devices receive commands to set the output type of the channel (e.g. 4-20mA, 0-5V or 0-10V) via the RS485 interface. The following steps are usually required:

• Use the configuration software supplied with the device or the supported Modbus protocol.
• Set the output type and corresponding range for each channel.
• Save the configuration and test the outputs.
• Note: Before configuring, make sure that you have wired the unit correctly and check that the power supply meets the requirements of the converter.
