Electrical Specifications
Note*: Pulse output, alarm output and status output use
the common terminal, therefore these functions
are not used simultaneously.

Transistor contact output can be obtained
simultaneously). In this case refer to “3:
WIRING”.
Analog : 4 to 20 mA DC, 2-wire system.
Transistor Contact Output* :
Open collector, 3-wire system.
Pulse, alarm, status output are selected by
parameter setting.
