Question about the renard with the 16 channel ssr built in

[tconley]

what are the values for the following resistors
R19
R20
R21
R22
R23
R24
R26

Also is there an R25 the numbering on on the coop board seems to jump from 24 to 26

What are the values for the following Diodes
D1
D2
D3

I am planning to be running this using rs485. Is there anything special i need to do?

[P. Short]

R19 = 27K (zero-crossing opto emitter resistor)
R20,R21 = 1K
R22,R23 = 27K
R24 = 330 Ohm (for power LED, for approx 10 mA through LED)
R26 = 120 Ohm (RS485 termination resistor)

D1 = 1N5229
D2 = 1N5239
D3 = 1N4001

Hopefully this agrees with the .XLS p/l from Dave, since I can't open that file on this (unix) computer.

BTW, this topic should be moved into the general sub-topic when/if I can figure out how to do it. And this entire category should be locked, so that all topics go into the sub-forums instead of here.

[P. Short]

Boy, you're fast. Anyway, it's moved now.

If possible, could you double-check my response with the contents of the excel file.

Howdy,

the BOM is here:

look for the XLS spreadsheet.

Thanks,

it is all working now sorry for the problem ended up being a bad serial cable.

Out of curiosity what lead you to check the serial cable?

I'm a noob so asking to learn :)
