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.
