DMX Relay Card 3221C

The 3221C-EP is a combined demultiplexer and relay board, ideally suited for all kinds of remote control: e.g. smoke machines, stroboscopes, wind machines (by frequency converters), and flourescent tube electronic ballasts - just to name a few. As the analog outputs are both, 0-10V and 1-10V compatible, any load may be driven.

The decoder features three DMX channels (CH1,2 = analog aout, CH3 = relay). Alternatively, the relay may be assigned to DMX CH1. Then the trip point is automatically set to 1% to match electronic ballast requirements.
