The electrical connection of transducer with 4mA ～ 20mADC output and
RS485 to see below.
Note ： when 4mA ～ 20Ma DC output and RS485 are used at the same time, signal
485 may interfere 4mA ～ 20mA DC output signal. The influence is related to
communication speed and frequency. “Setonline” controlling software could be
downloaded from our website.
