Safety relays

Safety relays

DOLD safety relays work together with emergency stop buttons, light barriers, safety mats, safety bumpers and safety rails. This combination ensures that machines are properly stopped in dangerous situations.

The choice of right safety relay is determined by the standards of the safety class, but also the required number of emergency stop circuits, the operating voltage, the required amount of relay contacts, the contact material and the possible need for a time delay.
