Velleman VM138, DMX-controlled Relay

With this module, you can control a relay via the widely used DMX512 protocol. This protocol is designed to control dimmers, scanners, moving heads, and other lighting with simple wiring. In many cases, switching the device on and off is required. This is where the module comes into play. The VM138 is a bus-controlled power driver. The relay is activated when the DMX value for the set channel is 140 or higher. The relay is deactivated when the DMX value for the set channel is 120 or lower.

Together with the K8062/VM116, you can easily set up a computer-controlled automation system.
