Multi-function safety relays are often the best choice for applications where single-function relays aren't capable enough and a safety-rated PLC is overkill. This white paper explains how to determine when applications will benefit from multi-function safety relays over other options.
Many machines and robots require safety circuits to stop all or part of operation in the event of an emergency. Safety circuits are also used to keep all or part of a machine or robot from running while there is human activity in close proximity, either for normal operations or maintenance.
