INstallation
8.3.1. Wiring the 4-20 mA output
The current output of the 8041 can be connected to a PLC or a
valve, either in sourcing mode or in sinking mode.
→
Set the selector of the electronic board to the sourcing or the
sinking position (see
Fig. 18 or Fig. 19).
→
Connect the 4-20 mA output in sourcing mode (see Fig. 18) or
in sinking mode (see Fig. 19).
→
Earth the device (see Fig. 18 or Fig. 19).

8.3.2. Wiring the frequency output
→
Connect the frequency output:
- to a PLC in PNP or in NPN mode (see Fig. 20 and Fig. 21) ;
- or to a load such as an electromechanical counter or a relay
(see Fig. 22),
- or to a load such as an electronic counter with its own power
supply (see Fig. 23).
