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.

Mount these timer relays directly to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Unlike mechanical relays, they have no moving parts, so they require less maintenance and last longer, are quieter, and switch faster.

Turn machinery, such as paint and conveyor lines, on and off after a set period of time.

Control two steps of an electrical process from a single relay—with two fully independent channels and 30 different functions, these relays give you a wide range of possibilities.

Protect components from voltage spikes while amplifying the relay’s signal and reducing interference for reliable transmission—these relays interface between your controller and system components to isolate the input and output circuits. They have multiple timing functions, so you don’t need to swap out your relay if you want to change their function.

Pair these potentiometers with a controller to monitor the position of moving parts or send instructions to an electrical system.
