Intrinsic Safety Connections

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.
