SINGLE CHANNEL DMX512 CONTROLLED RELAY

Description: The Single Channel DMX512 Controlled Relay receives DMX512 and uses the dimmer

level to open or close a dry contact relay. The relay is closed when the level exceeds 60%. The
relay is opened when the level falls below 40% . The unit is wired such that when the relay is
closed, the line voltage on the AC input (either 100 to 208 Volts or 220 to 240 Volts) is switched
onto the AC output (only the hot side is switched).

Line Input: The line cord is fitted with a parallel blade with ground (PBG) plug. The unit may be
pow ered by either 100 to 208 Volts or 2 20 to 240 Volts, 50 or 60 Hz. If a different plug is
required, cut off the parallel blade connector and wire on the desired plug using the following color
code: Green/yellow = Ground, Brown = Hot, Blue = Neutral.

Line Output: The unit's output is on an IEC-320 connector. This connector plugs directly into most
fog machines and hazer units. If a different connector is required, cut off the IEC-320 connector and
wire on the desired receptacle using the following color code: Green/yellow = Ground, Brown =
Hot, Blue = Neutral.

DMX Input: The DMX signal is applied to the male five-pin XLR connector.

DMX Output: The DMX signal is looped through to the female XLR connector to continue the signal

run to other devices. (All five pins are looped through).

DMX Termination: No internal termination is provided. The last device on a DMX run should be
terminated with a 120 ohm termination plug.

Starting Address: The starting address (the dimmer number that will control the relay) is set using
the three switches on the front panel. Set the number to the starting address.

Test Mode: Setting the address switch to 601 will close the relay to allow testing the output device
without a DM X512 signal. It is also a good way to verify that the DMX Controlled Relay unit is
working. When in test mode the signal indicator will flash.

AC Input Indicator: The red ac input indicator should illuminate whenever power is applied. If it fails
to light, first check that your outlet is good. If the unit is receiving power, the internal fuse may be
blown. To check the fuse, unplug the unit and remove the top panel. The line fuse is a 1/2 Amp
fast blow.

AC Output Indicator: The green output indicator will illuminate when the relay is closed, supplying
power to the output connector.

Signal Indicator: The green signal indicator will illuminate when a valid dmx signal is received. The
indicator will flash when the unit is in test mode (Address switch set to 6XX).
