Question

What is the difference between the Safety Relay and the Safety Relay Unit?

Answer

Safety Relays can be used to create safety circuits, of course, but measures such as mutual checks using duplicated circuits are required.

Safety Relay Units are blocks of circuits that combine safety relays with other components to make it easier to build safety circuits.
