Connect a +12VDC regulated power source to the +12V screw terminal input, noting polarity. Do not apply reverse or over voltage as it may damage the unit. The red LED will illuminate upon successful connection. It is recommended that a qualified electrician performs all connections and follows local electrical codes. See the specifications page for proper voltage and current rating of the relays and connections to insure they are within range.

DESCRIPTION
The DXRL (DPM-RL) is a DMX to relay driver and controller, with an optional 0 to 10 volt converter. Control 12VDC relays up to 100mA each from any DMX console or any DMX generating device. Control any devices that can controlled by power relay’s. With the optional 0 to 10 volt converter, control any 0-10 volt device with simultaneous relay control if desired. This functionality provides a 0~10 volt variable control signal and then at the low end of the variation provides the capability to shut off the power to the respective driver or device. See the 0-10V Option on page 3. The DXRL (DPM-RL) is equipped with dip switches for setting the DMX Start Channel, Threshold setting which sets the DMX level to trigger the relay’s on and off, Stand Alone Mode (no DMX) relay and output setting, and an Initialize switch for installing a 0~10 volt convert option. Also equipped with a 120 ohm DMX input termination switch, and LED indicators: red 12V power input, yellow DMX and status, and 8 green for relay status.
SETTINGS
NOTE – A RESET / RE-POWER IS REQUIRED FOR ANY DIP SWITCH SETTING CHANGES
OFF (down position) / ON (up position)
DIP Switch’s 1~9 DMX START CHANNEL: sets the DMX512 start channel (see
the DMX512 CHANNEL ASSIGNMENT TABLE document). The 1st Relay is controlled
(and optional 10 volt output) by the assigned DMX channel, the remaining
channels respond to subsequent DMX channels.
DIP Switch 10 THRESHOLD:
- OFF = 5% The respective relay will turn on at 7% and turn off at 4%
- OFF = 50% The respective relay will turn on at 49% and turn off at 51%
DIP Switch 11 STAND ALONE: (i.e. no valid DMX is present on the input terminal)
- OFF = All of the relay’s will be in the Open position (If the 0-10 volt option is installed all of the outputs will be at 0 volts).
- ON = All of the relay’s will be in the Closed position (If the 0-10 volt option is installed all of the outputs will be at 10 volts).
DIP Switch 12 INITIALIZE:
- Factory setup of 0-10V option (Perform only if necessary)
- OFF = Normal operation
- ON = Initialize function
CONNECTIONS
POWER: Connect a +12VDC regulated to the +12V screw terminal input noting polarity (reversed or over voltage may damage the unit), the red LED will illuminate.
WARNING!: Damage may result if REVERSE VOLTAGE or OVER VOLTAGE is applied to the input voltage terminals. Take great care that the +12V and ground connections are connected as marked on the PCB.
RELAY’S: If the DXRL (DPM-RL) is equipped with internal relay’s and screw
terminals, connect the external equipment with respective in/out relay
connections – Relay 1 input labeled “1 IN” is the supply power input, and the
output labeled “1 O” is the relay “closed” circuit output that connects to the
relay controlled equipment. See the unit legend or the specification page for
information regarding the power ratings of internal relay’s. Also see the
wiring examples on examples page.
If the relay’s are outboard or customer provided, connect the relay control
lines using the DB9 connector. See the wiring examples on examples page.
Install the relay’s in an electrical box or adequate enclosure and securely
connect wiring with the appropriate gauge wire for the current rating of the
installation, e.g. 10-12 AWG recommended or 16-20 Amps. If spade terminals are
used, crimp /solder .25″ wire terminals to the wires, Insert the LINE IN
voltage connection to the relay COM terminal by firmly pressing the wire
connector until it is seated all the way down. Insert the LINE OUT voltage
connection to the relay N.O. terminal – insure it’s seated all the way down.
CAUTION: If double poled relays are used the N.C. terminal will have line
voltage connected if the relay is off. If the N.C. terminal is not needed the
LINE IN and OUT connections can be reversed to prevent voltage at this
terminal. When activate, the relay’s will generate a small amount of heat
without a load, insure the relay’s don’t exceed the maximum heat specs under
full load and environmental conditions. See the specification page for
information regarding the power ratings of the relay control outputs.
NOTE: A QUALIFIED ELECTRICIAN may be required to interface the connections and all local electrical codes must be followed. See the specifications page of the DXRL (DPM-RL) for the proper voltage and current rating of the relays and connections to insure they are within range. The user is responsible for all uses and connections of the DXRL (DPM-RL).
VARIABLE 0~10 OUTPUTS: If equipped with the 0-10 volt option, connect the 0~10 volt outputs to the respective controllable input of devices. See the connection diagram in this document for an example of connecting 0~10 volt LED driver(s). The ‘C’ is the common connection and outputs 1-8 are the variable 0~10 volt outputs. NOTE: The 0~10 volt outputs are low current control voltages only-see specifications page for drive capabilities.
DMX512 INPUT: Connect a DMX512 signal to the input connector, (pin -2 and +3). The factory default of the terminating switch is ON (terminated) if the unit is not equipped with a DMX loop through, or OFF (un-terminated) if a loop through connector is provided. If the DMX input terminal is looped to another DMX device (limit 32) then set the terminating switch to “OFF”.
OPERATION
WITH VALID DMX: The DXRL (DPM-RL) will respond on the respective relay when the DMX level is equal to or greater than the threshold settings (see the dip switch threshold settings pg 1). If equipped with the 0~10 volt option, the respective 0-10 volt outputs will vary the voltage linearly in respect to the DMX level.
WITHOUT DMX: With DIP switch 11 in the OFF position all of the relays will be in the OPEN position (if equipped all of the 0~10 volt outputs will be set to zero). With DIP switch 11 in ON, all of the relays will be in the CLOSED position (if equipped all of the 0~10 volt outputs will be set to 10 volts).
REINITIALIZE HARDWARE: This is factory performed and not needed unless a communications error persists. To initiate: turn off the power to the PCB, set the INITIALIZE switch to the ON position, repower the PCB. The yellow LED will flash confirming the initialization. Then turn off the INITIALIZE switch and repower. If the error persists contact technical support.
LED INDICATORS
- RED POWER LED: +12DC is applied
- YELLOW DATA/STATUS LED:
- OFF = Indicates no DMX data is being received and the unit is in Stand Alone Mode
- SOLID ON = Indicates DMX data is being received
- SLOW BLINK = DMX communications or receive error has occurred (reset clears, If error persists-reinitialize hardware)
- GREEN RELAY STATUS LED’s: Indicates the respective relay is closed
0-10 VOLT OPTION
If the DXRL (DPM-RL) unit is equipped with the 0-10 volt output option, the outputs will control devices with a 0-10 volt control input. For example, some LED drivers only dim from 100% down to 10%, the DXRL (DPM-RL) provides the variable voltages to dim the LEDs. Some LED drivers are limited to dimming down to 10% or even 1% but not completely turning of the LED’s and some light is still being emitted. The solution is to control the power to the fixture using relay’s that are controlled by DMX. Once the DMX level drops below 10% the relay’s are OPENED to disconnect the power to the fixtures. When the DMX level is raised above 10% then the power is re connected to the fixture and then the DMX level will dim from 10% up to 100% as normal. The DXRL (DPM-RL) may have up to 8 relay control outputs and 0~10 volt variable outputs. Both sets of outputs respond together, that is, output 1 has a 0~10 volt output and a relay control output, both set to respond to the same DMX channel. For example, if the DMX start channel is set to 100, then output 1 of the 0~10 volt variable control and output 1 of the relay will respond to DMX channel 100. Insure the relay’s are capable of controlling the fixture or connected equipment power requirements. If multiple fixtures are wired together to create zones, insure the total power requirements are considered.
