Status Output / Alarm Output

IMPORTANT

Since this is an isolated transistor output, be
careful of voltage and polarity when wiring.
Do not apply a voltage larger than 30V DC or a
current larger than 0.2A in order to prevent
damage to the instrument.
This output cannot switch an AC load. To switch
an AC load, an intermediate relay must be
inserted as shown in Figure 4.4.13 or Figure
4.4.14.
*The alarm output operates from closed (normal)
to open (alarm occurrence) in the default value
(as setup upon plant shipment). Changes can
be made via the parameter settings.
