Data on safety engineering
Coil Type G1 642735 in ignition protection type intrinsically safe Ex ia IIC, for con-
nection only to certified intrinsically safe circuits with the following max. values:
Explosion group: IIC
Category: ia
Temperature class: T4 / T5 / T6
Max. permissible input voltage (Ui): 35 V
Max. permissible input current (Ii): 0,9 A
Max. permissible input power (Pi): see tables
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.
