Solid State Surface-Mount Timer Relays
Attach these relays to a flat surface using the mounting hole. They have no moving parts, so compared to mechanical switches, they require less maintenance, last longer, and are quieter.
Switches with a potentiometer (variable switch) allow you to adjust the delay within the range.

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.

Solid State DIN-Rail Mount Multifunction Interface Timer Relays
Considered solid state because they don’t have any moving parts, these timer relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, preventing damage to your components from voltage spikes, amplifying the relay's signal, and reducing signal interference. Use these relays with switching applications, such as small motors and pilot lights. They offer multiple timing functions in one relay. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relays disconnect from the socket for easy replacement.

For fast installation, mount these relays to 35 mm DIN rail (also known as DIN 3 rail). They also mount to flat surfaces. With no moving parts, these solid state relays last longer and require less maintenance, are quieter, and switch faster than mechanical relays. They provide a variety of timing functions in one relay.
Use relays with DIP switches for more precise control than knobs. They make it easier to set multiple relays to the same timing range.

DIP Switches
Configure instructions for electronic devices by sliding actuators to open or close each circuit. The actuators also make it easy to see your settings without turning on equipment. Since the contacts are gold plated, they have better conductivity and resist heat better than nickel-plated contacts. Push the contacts through holes in your circuit board, then solder them in place.

Remote Transmitters
Replace existing transmitters or team a transmitter and a receiver (not included) to remotely operate your automatic overhead door openers.
DIP-switch transmitters are compatible with Liftmaster openers that have a DIP-switch receiver. Use them to operate a single door. The three-button model has open, close, and stop functions.
