Safety Relays

Safety relays are electronic components that are used to control safety functions in machines and equipment. They are designed to detect faults and ensure safe operation by interrupting the power supply to the load or activating an emergency stop. Safety relays typically have two input circuits and output terminals, with safety contacts that are positively guided to prevent failures. They can be used in a variety of safety applications, such as safety gates, light curtains, safety doors, and two-hand controls.

Safety relays are used to ensure maximum safety and high reliability in safety systems. They are often used in conjunction with other safety devices and components, such as safety switches, safety mats, and safety inputs, to provide a closed safety circuit. Safety relays are typically monitored by a monitoring device to ensure proper operation.
