Relays

High-Current Relays

High-Current Relays

Also known as contactors, these relays are rated for motors with Â½-50 horsepower and are used with large motors and lighting systems.

Low-Current Relays

Low-Current Relays

Rated up to 15 amps.

Medium-Current Relays

Medium-Current Relays

These relays are rated for motors with 1-3 horsepower or 15-90 ampsâ€”use them with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

High-Current Vehicle Relays

High-Current Vehicle Relays

Suitable for DC-powered equipment such as forklifts, floor scrubbers, and trucks.

Latching Relays

Latching Relays

A single, momentary input voltage switches these relays and locks them in position, so they don't require a constant input voltage to stay on or off.

Alternating Relays

Alternating Relays

Split run time between two devicesâ€”this relay will automatically alternate between them.

Signal Relays

Use these relays with circuits that control electric signals for PLCs and microprocessors.

Air-Actuated Relays

Also known as an air-to-electric switch, this relay converts an air signal to an electric signal.

Other Electric Relay Controls

Timer Relays

Timer Relays

Set a time delay before these relays open or close a circuit.

Programmable Logic Controllers

Programmable Logic Controllers

The functionality of a relay, timer relay, and switch in one unit allows you to program complex automation jobs.

Switches

Switches

Actuate switches to open or close a circuit.

Relay Sockets

Relay Sockets

Mount to DIN rail or flat surfaces, then plug your relay into the socket for fast installation.
