DC Input Modules (IDC-5)

Has anyone interfaced these to a stamp yet? They are optoisolated DC Input
Modules that I want to interface and I have just a few questions. Brand of the
modules Gordos, Tyco.... I'm using the Digikey PN# 184583
1: Verify that I understand the pin out of the module:
Pin 1) 24vdc Signal In (switched input I'll be checking the state of)
Pin 2) Ground
Pin 3) 5vdc +
Pin 4) Logic 5 vdc out
Pin 5) Ground
2: Can I hook Pin 3 directly to a stamp input pin? Do I need a current limiting
resistor in series?
3: Do I need to pull it down or does the Input module already do that?
Thanks, I'd rather ask to be sure because I don't want to burn up a $50 stamp.

for the PC Board. I wanted to make these modules removable.
Thanks

Your pin out is correct.
I use a 470 ohm resistor and LED in series with pin 3 to + 5 for all I/O
modules.
This provides the pull-up needed for the input modules.
It also current limits the output modules to about 6 ma. per pin. This keeps
them low enough so you don't have to worry about the maximum output per pin
(or group of 8 pins).
The mounting hardware for the Opto 22 style modules is:
Opto 22 part numbers:
Pin Sockets G4MODSOCKET
PCB Nuts G4PEMNUT
This is for the G4 Series of modules.
They are available from Allied Electronics. (www.alliedelec.com)I don't have
the Allied part numbers handy as I purchased 100 of each a few years ago, and
don't use them.
They are hard to mount in a PC Board, and if you use Express PCB they don't
have the right hole sizes. You have to drill out the holes and then repair the
PCB traces.
It looks hokey for an industrial PC Board.
You can also use the Opto-22 I/O boards with a ribbon cable from the Stamp.
These are also available from Allied. They come in 4, 8, 16, and 30 position
racks.
You have to make sure you do not exceed the maximum current draw for any 8
pin group on the stamp with the output modules.
I make sure I have 1 inputs in each 8 pin group and then you do not have to
worry.
I use the Mini I/O Modules. I get them from Digikey also.
I solder them to the PC Board. This is much simpler for small production runs
and does not suffer from intermittent connection problems.
The part numbers are:
Type Grayhill # Digikey #
DC Input 70M-IDC5 GH7027-ND
DC Output 70M-ODC5 GH7024-ND
AC Input 70M-IAC5 GH7026-ND
AC Output 70M-OAC5 GH7022-ND
These modules do not have the LED indicator, so adding the LED Pull-up
circuit gives an indicator of the I/O Status.
I have used both approaches for the past 5 years and have yet to have a
failure of a Stamp or I/O module.
The PC boards I use for my internal industrial projects will be available in
a few months.
The website <A HREF="www.StamPLC">www. StamPLC</A> is under construction now.
Thank You and Good Luck,

saying it failed.
Are you sure the resistor and LED go to Pin 3? My pin out shows Pin 4 as
the 5 vdc logic pin that would go to the stamp and be high or low depending
on the signal going into Pins 1 and 2 of the module.
Maybe I'm simply misunderstanding your message or the datasheet.
Thanks,
Richard

Let me backtrack a bit. I was interrupted a few times writing the e-mail. I
need to turn off the ringer once in a while.
When I use the Opto 22 modules I purchase their I/O rack. They have a built
in pull up resistor from + 5 (Pin 3) to the logic Output Logic Pin (Pin 4).
When using this board I am careful about exceeding the Stamp Pin Capacity (for 8
pins). I have not tried the LED and Resistor Setup with Full size screw in
type of modules as they are too hard to mount on home spun PC boards. The Pem
Nuts pull out too easy and the solder in pin connectors just don't seem to work
as well as the robotic assembled units.
With the Grayhill Mini modules I connect the LED and Resistor to Pin 3 of the
Output modules and Pin 4 of the Input Modules.
Hope this cleared the Mud a little.
