Usually the DIN rail clips have an aluminum bar with standoffs like this

thanx JT, that looks to have the shorter spacing. I was considering adding another hole in the Hammond one or slotting the holes in the Toolenator 3000 PCB to make them work.

here's a CAD Toolenator 3000 PCBA as I build the BoM. The DIN rail clip doesn'
t fit the holes in the PCB, still looking for the proper one, this one is from Hammond.


Sorry, been a bit busy the last couple days. I believe the DIN rail brackets are these:

They take a #6 screw, if I'm not mistaken....

thats great thanx. the others Im still having trouble with are the optoisolator exact part number, I have the family but cant seem to find a match for the 50-300% in the diagram Also the c1, c4,c5 and c6 capacitors are giving me trouble identifying the type. I have the rest identified.

The optocoupler we have on the board is labeled FL 817C F511. Dale specified a Sharp PC817 on the schematic and anything similar will work.

C1 is a 1uF 6V (min) Tantalum
C4 is a 1uF 25V (min) Tantalum
C5 is a 470pF ceramic
C6 is a 0.002uF ceramic on the schematic (on the board we have a 332J)

Most of these we had laying around so I don't really have links to specific parts.
Hope this helps,
-Tom

Hi Tom,

attached is the costed BoM as of today. I haven't ordered anything yet. Could you look through it and see if anything is incorrect? I am an ME after all so I haven't ever really specified EE components before. I gave it the old college try though :) Tracking shows I will get the bare PCB's tomorrow.

Scott

Nicely done, looks correct to me. You left C4 blank, I assume you are just going to use 2 of C1?
