About Relays

About Timer Relays

3 Circuits

Use these relays with large motors and lighting systems. Also known as IEC contactors, they are built to International Electrotechnical Commission (IEC) dimensional standards. All have recessed terminals to prevent contact with live connections. Mount to 35 mm DIN rail.

Auxiliary contacts allow you to add a signaling device or control another relay. Add one front-mount contact per relay or two side-mount contacts per relay.

Thin Signal Relays with PLC Protection and Socket

8 Terminals

Prevent voltage spikes from damaging your programmable logic controller or other sensitive control device. Thinner than other signal relays, these fit in tight spaces. Plug them into the included socket for fast installation; they disconnect for easy replacement. Use these relays for low-current switching applications such as small motors and pilot lights. The included relay sockets mount to 35 mm DIN rail.
