Wiring the panel-mounted transmitter, without relay
Connection to a PLC
The 4-20 mA signal originating from the transmitter without relay is sent out on the wires of
the 12-30 VDC power supply. The signal can be transmitted to a PLC (see Fig. 3.7).
Connection to the conductivity sensor type 8220
Assemble the EN 175301-803 cable plug of sensor 8220 as described in Fig. 3.4 then
connect the sensor to the 8225 separate transmitter.
