3 INSTALLATION
Connection of electronic module SE35, 115/230 VAC, with relays and cable
glands, to a PLC
The 4-20 mA output of the transmitter, 115/230 VAC, with relays can be connected to a
PLC. Depending on the PLC type, position the "sourcing / sinking mode" switch [1]
properly (see following fig. and fig. 3.8).
