Safety relays are devices that generally implement safety functions. Relays and contactors were used to control plant and machinery in the early days of control technology. In the event of a hazardous situation, the actuator was simply isolated from the energy supply. This type of protection system could be manipulated in the event of a malfunction, disabling the protective function. Special relay circuits, such as the three-contactor combination, were the first designs to come out of deliberations into how this could be avoided.
The design technology is the main difference between the safety relays. Three types of safety relays are Classic contact-based relay, Relays with electronic evaluation and contact-based volt-free outputs and Fully electronic devices with semiconductor outputs relays.
