I have a magnetic switch that is rated 0-36VDC, but only 0.5mA. It looks like all the input cards for the 205 are at least 8mA @ 24VDC. Anyone know of a TTL - > RELAY device I can buy to avoid making my own custom transistor circuit?

    You could also try Continental Industries. I use their Output modules all the time for an app which outputs at 5vdc TTL.

    Very inexpensive. around $20 per module

    Forgot to mention that they are DIN rail mountable.
