8.4 ALARM OUTPUTS
The low alarm and high alarm/pulse output can be connected to suitably certified
devices providing 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 that 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.
