Built into a terminal block, these switches mount to DIN rail.

Safely transmit power to switches and sensors in highly volatile areas. Commonly used in refineries, power plants, and wastewater-treatment facilities, these barriers use a NAMUR signal to reduce the current and voltage coming from your power supply—preventing sparks and ignition.

With a shallower depth than most other starters, these fit in narrow spaces.

Save electricity and extend motor life by reducing the motor's starting current.

Mount these controls to DIN rail inside a control panel.

Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation.

With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission.

Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.

Receive signals from safety monitoring relays or controllers to switch devices off and on because of a system failure.

The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding.

Operate equipment that cycles on and off from your control cabinet.

Often used to regulate the speed of AC fans or keep a heater at a set temperature, these relays connect directly to sensors to calculate and adjust output power. This allows you to use an analog input without converting it to a digital signal to control output power.

Prevent changes in frequency from damaging sensitive equipment.

Protect electrical equipment from overcurrent and undercurrent damage—these relays continuously monitor current flow.

Mount these Ethernet switches to DIN rail to bring connections closer to where you need them.

Smaller than other PLCs, these controllers save space in your control cabinet. They combine the functionality of a relay, timer relay, and switch in one unit, so you can program simple automation jobs.

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.

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.

Reduce voltage fluctuations and stress on shafts and bearings when starting up three-phase motors. These timer relays start with motor contacts in a star configuration, then switch to a delta configuration after a set delay.

Whether installed in an electrical cabinet or hard-to-reach area, these timer relays are controlled remotely from your smartphone. They connect to your phone via a free downloadable app so you can set time delay ranges, adjust settings, and save programs.

Mount these temperature controllers directly onto DIN rail for controlling systems with rapid, unpredictable, or complex temperature changes. They turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control.

Also known as supplemental protectors, these circuit breakers mount directly to DIN rail downstream from a branch circuit breaker to protect a single piece of equipment.

An electronic trip mechanism makes these circuit breakers fast, precise, and consistent. They continuously monitor current and trip at a precise value compared to the much wider current range in traditional thermal-magnetic breakers.
