8.4 ALARM OUTPUTS
The low alarm and high alarm/pulse output can be connected to suitably certified devices provided the circuit is protected
with a barrier with the maximum safety parameters:
Uo = 28V
Io = 93mA
Pmax = 0.653W
The input capacitance on these terminals is 0.1uF max and the inductance is negligible.
Note: The two alarm outputs must be kept as independent IS circuits and each protected with their own barrier. It is not
permissible to connect these circuits via a common barrier.
