> Hi all. We have a controller board that is used with 24 pin
> processors that I have been using for some time with great
> success and am thinking of making it available to others but
> first I would like to see if their would be any interest in it.
> Basically, the board has 8 inputs and 8 outputs. The inputs are
> switchable between opto-isolated digital inputs and direct
> connected analog ins. Capacitors and resistors are included on
> the board for RC time type analogs ins. The outputs are
> switchable between transistor out (cmos sink 10 amps I think),
> and on board relays 16 amp @ 250 vac. The transistor outs can
> still be used when its associated relay is being used. All
> outputs and digital ins have status LED’s. Sockets are also
> provided to accept 1 dual A/D converter and 1 D/A converter. The
> board also has a second 24 pin socket with its own DB9 connector
> that connects 2 I/O pins to the first 24 pin socket that can be
> used to pass data back and forth for dual processor projects.
> Another nice feature is that both 24 pin sockets have extended
> square pins on the back side of the board for wire wrapping if
> required. The power input will accept 8 to 30 VAC or VDC and the
> onboard switching power supply has enough extra power to supply
> other small 5 volt devices. All electrical connections are made
> with screw type terminal strips.

> Thanks for your thoughts.
