The XTBA DMX Relay 4-DIN Rail takes DMX in to control four change over relays in a DIN rail case. Now includes RDM. Mains powered (or can be supplied to run from 24 to 48VDC for use with LED PSUs), the Relay 4-D offers a simple method to interface external systems to DMX control. DMX is based on the RS-485 serial interface standard. Typically, three-pole XLR plugs are used for cable connections. Before I go any further- I need to cover programming the D1 Mini. It isn’t too difficult, but I’m also not going to get into a whole tutorial on using the Arduino IDE. There are a LOT of resources online. I just want to cover the specifics for this application. There are other “DMX” or “E1.31” test apps available for Windows, Mac, iPhone/iPad, Android, etc. Once you have things working, you probably want to install your relay into some kind of a box. Here is what I did…

Relay circuit board, includes Northlight Systems DMX512 to Relay circuit board, includes

attachInterrupt(1, PinB, RISING); // set an interrupt on PinB, looking for a rising edge signal and executing the "PinB" Interrupt Service Routine (below) Important: The D1 Mini can only access 2.4Ghz WiFi networks, not 5Ghz, so be sure to use an appropriate network. railSwitch offers a pre-set mode that enables it to run stored programmes without an active DMX controller. Other features include data loss mode (which determines what railSwitch should do in the event of loss of the DMX signal) and test mode, which is particularly useful during commissioning. Once you have finished editing things, you are ready to upload your Sketch to the D1 Mini. Plug it into your computer using a Micro-USB cable. You might see a brief flash of a blue LED next to the WiFi antenna, but otherwise not much will happen.

railSwitch is an elegant solution to the automation of various devices in theatre, touring and architectural markets. Applications include animatronics, fog machines, theatre practicals, cue lights and video remote control.

Northlight's Relay board will receive DMX512 digital protocol and standard 0-10 VDC analog to control mechanical relays. The right products that are readily available and with trusted performance you can count on. Ships same day if entered before noon or next day if entered after noon! You will also need a “D1 Mini Relay Shield”, which again you can find through a variety of online retailers. D1 Mini Relay Shield You should get an instant answer on whether your application has been successful, though in some rare cases Klarna or V12 may need to look at the application in more detail.

It’s been proven to work better in crowded wireless environments, so your signal can get through no matter where you are. Now- create a new “Sketch” (Program) and call it something like “D1_Relay_Controller”. Copy and paste the following into it: Collection and delivery costs are included for the first 2 years in the event of an item becoming faulty pinMode(pinB, INPUT_PULLUP); // set pinB as an input, pulled HIGH to the logic voltage (5V or 3.3V for most cases)
