Relay accessories repair, maintain, or enhance the functionalities of electrical relays. DIN-rails and mounting hardware secure relays onto surfaces and inside electrical enclosures. Surface- and PCB-mounting hardware secure relays onto printed circuit boards. Relay heat sinks dissipate the heat created by solid-state relays. Relay retaining clamps and clips attach relays onto DIN rails and sockets. Relay protective covers and enclosures protect relays from damage and accidental contact. Relay timers activate at specific intervals to control power or sequencing. Relay probes and sensors pair with monitoring relays to detect operational and environmental changes. Relay communication modules enhance and modify relays to increase their functionalities.
