When selecting the voltage supply for the safety controller, you need to take into the account the no
load current of all modules of the station, and the peak current consumption of all electrical consumers
connected to the outputs of the safety controller. The maximum permissible supply current depends,
amongst other things, on the ambient temperature and must not exceed the permitted value of 8 A (Ta
= 55 °C). Take into consideration the effect of lack of ventilation or the power loss in cables or other
devices on the ambient temperature in the control cabinet.
