Data on safety engineering
Coil Type G1 642735 in ignition protection type intrinsically safe EEx ia IIC, for
connection only to certified intrinsically safe circuits with the following max. values:
Explosion group:
Category:
Temperature class:
Max. permissible input voltage (Ui):
Max. permissible input current (Ii):
Max. permissible input power (Pi):
The maximum permissible voltages and the associated maximum permissible short-
circuit currents for the corresponding gas group may be taken from Table A1 in the
standard DIN EN 50020, Edition 1994.
As an example, some pairs of values for the ignition protection type EEx ia are given
for the gas group IIC.
