DC SSR only working at half

**LabRat** · 07-17-2010, 12:34 PM

Same voltage reading on all four outputs?

What if you don't use the REN-C? (I'm assuming the REN-C F/W wouldn't know that you have DCSSR's attached, so it's output may not be just "ON".. and then later .. "OFF")

Have you got an SSR tester, that you could just close a switch to turn the SSR on? As you are home etching there are a couple of samples in the FILES section. It might help. (The testers usually double as a cable tester as well, so it's a reasonable investment of time to make one)

I am just asking here: The Firmware on the Ren-C, do you not have to set it up to controll DC and not AC ?

I dont have one so I will make one and get back to you on the results, I took a volt meter and had a look at the input voltages from the grinch which is controlled by the ren-c and I got 2.30 volts, I dont know if this is normal for the ren-c or if it should be 5v like the grinch outputted.

Thanks Stephen

I'm not sure what software is on the pic, its just what wjohn sent me

The Ren-C only works with a Grinch or 595 board and does not have any capability for DC or AC. The Ren-C is a translator, of sorts, that translates a serial signal into a format that the Grinch/595 can understand, which normally are connected to the parallel port.

Yes, I know what the Ren-c does, (learned for the wiki ;) ), but I was just wondering, because on a eg. Ren 64 you have to do that :o

Is the program in the ren,c set for 60hz because soakes needs 50hz for the UK. ? would that be the cause.

It works ok with mains lighting, however there is a flicker but that could be the hardware in the switch

That would have been my other question, thats good. Back to the drawing board!.

The Ren-C code is self-adjusting for 50/60Hz. Also DCSSRs work on active low signals as the ACSSRs do so you do not need to invert the signal out. You only need to change it when using inverting drivers such as ULN2803s or transistors. AFAIK there are no changes to the code required for Ren-C's but Phil could confirm this...
