How to wiring and reading RHP-2D11-LCD sensor with PLC micro850 via module IF4

Before wiring sensor can reading diagram written on labeled of sensor

(1) Wiring RHP-2D11-LCD sensor

Terminal (1)-green wire is Humidity signal

Terminal (2)-red wire is conected with +24VDC supply

Terminal (3)-white wire is Temperature signal

(2) Connect sensor with PLC micro via module IF4 to reading

If sensor wiring by current output (4–20mA) then doing as bellow:

The terminal 1 (green wire) of sensor conected with terminal 2 (CI-0) of IF4.

The terminal 3 (white wire) of sensor conected with terminal 5 (CI-1) of IF4
