FA-1
MONITOR
Analogue output (Out 1)
The analogue output is electrically separated from the pulse pick up supply and
the 24 V DC supply up to a potential difference of 500 V DC. The electrical sepa-
ration used is not suitable to separate mains circuits from SELV circuits.
No dangerous contact circuits must be connected to the analogue output.
Load circuit relay output (Out 2)
To prevent excessive wear and to comply with the EMC regulations interference
suppression of the contacts is required for switching inductive loads.
If the relay is used to switch very small currents (e.g. PLC inputs), considerable con-
tact resistance can arise. In this case use the transistor output.
Load circuit transistor (Out 2)
The transistor output needs an external voltage of 24 V DC at terminal 3, this volt-
age should be supplied from an external power supply. The reference point (GND)
of the external power supply must be connected to terminal 1 of the monitor, oth-
erwise no switching operation is possible.
The device shall be supplied from an isolating source and protected by an overcur-
rent protection device such that the limited voltage circuit requirements in accor-
dance with UL 508 are met.
