TWO CHANNEL DMX512 RELAY PACK

model DMX2REL5A

Description:

This DMX512 Relay Pack receives DMX512 and uses the dimmer levels to open or
close dry contact relays. The relay is closed when the level exceeds 60%. The relay is
opened when the level falls below 40%.

Connections:
Line Cord. The line cord is fitted with a parallel blade with ground (PBG) plug. If a

different plug is required, cut off the parallel blade connector and wire on the desired
plug using the following color code: Green = Ground, Black = Hot, White = 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).
Relay Outputs. One relay is connected to each male 3-pin XLR style connector. The

outside connector carries the contacts for the first relay. The inside connector carries
the contacts for the second relay.

The pin outs are: Outside Connector Inside Connector

Pins 1 Relay 1 common Relay 2 common
Pins 2 Relay 1 normally open Relay 2 normally open
Pins 3 Relay 1 normally closed Relay 2 normally closed

Controls:
Starting Address. The starting address (the dimmer number that will control the first

relay) is set using the three switches on the front panel. Set the number to the starting
address. A test mode is provided that closes the relays regardless of the DMX input.
Setting the address switch to 601 closes relay #1. Setting the address switch to 602
closes relay #2.

Indicators:
Power Indicator. The red power 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, remove the
top cover. The line fuse is a 1/2 Amp fast blow.

Signal Indicator. The green signal indicator will illuminate when a DMX512 signal is
received. The indicator will flash when the unit is in test mode (address switch settings
of 600- 696).

Relay 1 Indicator. The green relay 1 indicator will illuminate when the first relay is
closed.
