PCB Selectable features:

12VDC Power Supply
DIN Rail Clips
DIN Rail 8"
Screw Terminals Omitted - If mounting the PCB on a faceplate with the LEDs and DIP switch accessible from the front of the enclosure, the screw terminals can be omitted and the wires soldered directly to the board to allow the pcb to mount flush.

CUSTOM DMX ON/OFF THRESHOLDS:
If the dip switch threshold setting is 50% then the relays will turn on at 51% (DMX level 131 of 255), and the relay will turn off at 49% (DMX level 126 of 255).
If the dip switch threshold setting is 5%" then the relays will turn on at 7% (DMX level 18 of 255), and the relay will turn off at 3% (DMX level 9 of 255).
CUSTOM on/off settings are possible and factory set, contact us for more information, or select CUSTOM and add the desired ON/OFF value settings in the comment section. Note: Some analog controllers may vary while idle, a small window is recommended of at least 2%.

LED and Screw Terminal Mounting

LED's top flush mounted, screw terminals top mounted - LED's are installed flush to the PCB and the screw terminals are top mounted. Standoffs are installed on the bottom at .375" in height. PCB access is top access inside an enclosure.
LED's top mount extended for faceplate assembly, screw terminals bottom mounted - as shown in photo. LED's are top mounted and will extend through predrilled user enclosure holes for faceplate style assembly. Screw terminals are mounted on the bottom. Standoffs are top installed at .25" in height.
LED's - bottom mount extended for faceplate assembly, screw terminals top mounted - LED's are Bottom mounted and will extended through predrilled user enclosure holes for faceplate style assembly. Screw terminals are mounted on the top of the PCB. Standoffs are bottom installed at .25" in height. Note the dip switches will not be accessible on the user faceplate.

DXRL SUB PCB Add On: A small sub PCB is required to add the 8 channels of 0-10 volt outputs 20mA each. This sub PCB is factory mounted on the opposite side of the LED's.

DXRL is a DMX 512 8 channel relay controller with optional 0-10 volt variable analog outputs. Assign a DMX start channel, assigned by dip switches 1 ~ 9, and the respective relay will turn on or off depending on the respective DMX channel level. Connect up to 8 independent relay's [SINK/GROUND Driven] (up to 100mA ea), coil/mechanical or SSR (Solid State Relay) relay's. The DMX level threshold or trigger value can be set to 5% or 50% via dip switch 10, and the standalone (no DMX present) setting can be either full on or all off.

The optional 0-10 volt outputs can be used to control LED drivers or any 0-10 volt controlled devices. The 0-10 volt outputs correspond to the respective DMX channel, that is, if the 1st relay is controlled by DMX channel 1, then the 1st 0-10 volt output is controlled by DMX channel one. This is useful, for example, if an LED driver doesn't dim to 'full off' then the power can be disconnected to the 0-10V driver or fixture using the corresponding relay circuit.
