2 Channel DMX Relay Switch PCB

A 2 channel DMX relay switch for switching loads up to 10A at 240V AC.

The DMX-switch operates on the standard DMX512 network and requires 2 channels for operation. The base address may be set between 1 and 511.

Standard board fitted with two 10A/240V AC mechanical relays. 

PCB Size 109 x 77 x 30mm high 4mm mounting holes @ 101mm x 63.5mm  

Connections DMX:  

  3-pin screw terminal connection for input/output, 120R termination resistor Loads:  Twin 3-way terminal blocks Power Supply: 12V at 500mA via 2.1mm socket (centre positive) or 2 way terminal block. 

Settings

Base address Set the required base address using the DIP switches 1 through 9. Add-up the values where the switch is set to the on position. The base address is read continuously. 

Relay status   JP1 OFF       

Indicator Leds show the state of each relay DMX value <87% 224 Off /  > 87% 223 On 

JP1 ON When set to the ON position, relays are interconnected and operate from the base channel address as follows 

 DMX Data Value                        Relay 1 Status      Relay 2 Status  Less than

80/32%                                                 ON                                 OFF 

Between 80 and 160/ 32-62%         OFF                                OFF 

Greater than 160/62%                      OFF                                 ON
