Gas Valve/Control Setup

[autobaun70]

I am working on setting up an automated MLT, using a basic brutus 10 design, and have a few questions about the electronics.

I will only be controlling 1 burner for now, but may automate the HLT later on. I am looking at the Auber SYL-1512A controller. It lists the input voltage at 85V A/C - 260V A/C, and the output voltage at 240V AC. Is the output voltage a constant 240V, or does it replicate the input voltage? Also, can I just run that directly into a transformer, and control a honeywell gas valve (24V A/C), or do I need to tie the controller to a relay, and keep the 24V a/c transformer switched from there?

Like pretty much all controllers, there is a rating for the input voltage used by the device itself, and then there are one or more ratings for the voltages it can switch or otherwise control.

So "85V A/C - 260V A/C" is the operating voltage - what the device needs for itself to function - and "output voltage at 240V AC" is the max voltage rating for the relay output.

If you want to control a 24vac device (solenoid, for instance) you'll need to provide a separate transformer to wire through the SIL output relay and on to the device.

The manual is pretty thorough on your options...

Cheers!

So assuming I am running the controller on 115v ac what voltage will the relay output be?

The same as the input.
Check the manual, I think on mine I can use 115VAC to power the PID and I can put another source to the input that would also be the output. So in your case it could be 24VAC.

Ok, I was finally able to get a good enough connection to get the PDF downloaded. Best I can tell, you can switch up to 3 amps of any voltage (a/c) that you wish. Looking at it, you can use a jumper and use the voltage that you are running the controller off of, or feed a different voltage to it and switch that, which is my plan. I went ahead and ordered a contactor just in case that doesn't work, as they were only 8.95 and I a sure I can reuse it elsewhere if it isn't needed for this project.

I ended up ordering the 1/16 DIN rather than the 1/32 DIN just for the extra display line.

Whatever voltage you connect to the output relay....
