Relay Controllers That Stand Above The Competition

Our RS-232 Serial and Ethernet 32-Relay Controllers are large, powerful, and very easy to use. Few companies offer relay controllers of this size and we believe our 32 relay controller stands far above the competition.  You can send commands to activate relays, deactivate relays, control all the relays at one time, plus you can send commands that tell a relay to turn on for a few seconds, minutes, or hours.  You can assign 16 timers to any of the 256 relays, and set the timers to go off after the duration has expired.  We have also added a Server Reboot Pulse timing feature that is particularly useful for rebooting up to 16 servers.  With features like these and 32 Relay Channels, it no wonder we stand above the competition!

Latest Advancements

Look for our ProXR series controllers for the latest advancements in signal switching!  Available in USB Relay, 802.15.4 Wireless Relay and RS-232 Relay configurations, the ProXR Series is capable of controlling up to 256 relays.  Whether you need power switching or DPDT signal switching, the ProXR Series are built from the ground up with Expansion in mind.  Simply Chain the XR Expansion Modules, one after another, to meet your computer controlled switching requirements.
