Control and diagnose issues with safety-critical circuits. These relays have a microprocessor that monitors safety components, such as emergency stops and light curtains, and sends a signal to stop the operation if a failure is detected and restart when the issue is resolved. They also help with diagnostic tasks because of their feedback circuit, which allows basic relays to communicate their status back to the safety relay. These relays have a duplicate set of input and output signals, so they’ll still stop the controlled device if one of the inputs fails.

IP20 rated, they have recessed terminals which prevent fingers and other objects from touching live circuits. These relays have been tested to multiple safety standards and can help achieve PL, SIL, or CAT system ratings. They also meet ISO and IEC standards for machine safety.

Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation.

Auxiliary contact blocks (sold separately) allow you to control more components, such as signaling devices or basic relays.

With a built-in web server, these relays can be remotely controlled over any IP network, including the Internet. They connect to your network either wirelessly or with an Ethernet cable (not included). No programming or software is required to operate these relays. Instead, use your web browser to input the relay’s IP address and the website guides you through simple menus and drop-down lists to set your parameters. Alternatively, you can use these relays with a PLC or without a computer at all if you use one relay as a controller for another relay.

Each circuit has a digital input that can be used to control the relay or a remote relay over the IP network. You could also use the digital input to monitor a separate device, such as a push-button or door alarm switch. These relays can be set to automatically restart network devices, such as computers, even when they fail to respond to relay signals. LED indicators let you know if there’s input and output voltage and if the network is connected and active. All meet at least one safety standard.

Mount these relays on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces.

Relays that control 2 circuits can also be programmed from a downloadable app or programs written in BASIC script, making them easy to customize. The website logs and stores data and device information.

Power over Ethernet (PoE) compatible relays can receive power from PoE cables (not included).

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.

Relays that control 4 circuits require a relay socket (sold separately) to attach to DIN rail.
