Velleman VM138 DMX-Controlled Relay

DMX-Controlled Relay This module allows you to control a relay by means of the well-known DMX512 protocol. This is used to control dimmers, scanners, moving-head spots and other lighting devices with a simple wiring. In some cases, a simple ON/OFF selection is desired. there is where this module comes in. It is actually a bus-controlled power driver. The relay will be activated when the DMX value of the set channel equals 140 or more and turns off when the value is 120 or less. Together with our K8062/VM116, a computer-controlled automation will be very easy to build.
