WhiteWing 16 channel DMX relay

[Thorfun]

I see that Mike from WhiteWing is now offering a 16 channel DMX relay http://whitewing.co.uk/dmxrelay.html.

 

I wonder if he saw an opening in the market when I was talking to him about how expensive the Loxone relays were? (and no I'm not looking for commission!) 

 

wish these were available when I was putting my Loxone cabinet together, could've saved a small fortune over the Loxone relays. at over half the price per channel it will be my next purchase when I need more relays for the basement lighting. it works out at £10.93 + VAT per channel compared to the £23.61 +VAT per channel for the Loxone relay . I already have a 16 channel mains dimmer and 48 channel 24V dimmer and both work great.

You've seen his youtube channel mikeselectricstuff ? Fascinating if you've always wondered how a PCR / bomber sight / baggage xray works?

There are lots of ESP32 based relay boards available on AliExpress at all sorts of relay combos.  The build quality and electrical design of the better named suppliers is excellent.  The advantage of going the ESP route is that you can load these OTA with ESPHome or Tasmota firmware which makes them v, easy to integrate to Home Assistant, etc.

 

You need to be very aware of the contact life, especially without snubber protection (or flyback diodes if switching DC).   I chain mine to contactors if I am driving anything about 1A, but this definitely requires snubber/flyback protection for the control relays.

I went through looking at getting my DMX relays from AliExpress and even though they're cheaper I decided that in the end I wanted to support a UK (local-ish) business. Plus Mike was very responsive to my many emails and you can't put a price on that sort of customer service.

Was fortunate timing for me as I was just in the process of ordering a dimmer from Mike, so ordered the relay too.

I'm sure it'll work fine but please let us know how you get on. I might need one soon-ish!

Will do! Currently just building it up on the test bench so will be a while until I can test it fully.
