Circuit Board Safety Relays
Reduce connection errors on circuit boards that control machine guards and other safety devices. Also known as force-guided contact relays, they have contact pairs that won’t close at the same time, even if contacts stick or weld shut. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes. Use them to control high-power components, such as fans and heaters, from a low-power circuit.
Relays with surge suppression coverage protect sensitive electronics from damage and malfunction by eliminating voltage spikes. Switching off a relay can generate surges of 300 to 500 volts, but a diode within these relays suppresses these surges. An LED indicator on these relays lights up when they’re on, so you know at a glance if they’re wired correctly.

Timer Relays
Turn machinery, such as paint and conveyor lines, on and off after a set period of time. These timer relays plug into relay sockets (sold separately) for fast installation and replacement.
Relay sockets mount on 35 mm DIN rail (also known as DIN 3) or flat surfaces.

Multifunction Timer Relays
Get a variety of timing functions in a single relay. All relays plug into relay sockets (sold separately) for fast installation and replacement.
Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or can be mounted to a flat surface.

Solid State Versa-Mount Multifunction Timer Relays
Install these relays in a panel cutout or plug them into a relay socket. Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, are quieter, and switch faster. They give you a variety of timing functions in one relay.
Single-circuit relays give you additional flexibility—they have two types of delayed switch-off (delay-on-break) functions and two types of signal on/off delay functions.

Mounting brackets (sold separately) are required to mount relays into a panel cutout.
