Acc5E3 I/O

[KennNova]

We would like to use inputs on the Acc5E3. However, I cannot seem to find a typical input circuit diagram in the Acc5E3 manual. Nor can I find a spec on the sinking/sourcing voltage.

Under the heading IO Port Setup, the manual describes how to configure the general purpose IO as either inputs or outputs and inverting or non-inverting. For an inverting I/O point, 0=+5V and 1=0V, and for a non-inverting I/O point, 0=0V; 1=+5V. It is TTL logic. A connection diagram would be helpful, wouldn't it? We are getting those into the I/O manuals now as they are created or revised.

Thanks Greg. The TTL signal level is a show stopper for us. 5 volt logic is pretty much useless in our market of industrial control. We'll have to go another route for the extra I/O we need.

I could make a recommendation based on the I/O requirements. Note that the ACC-5E has a JIO port which connects to Opto-22 style boards, and a JTHW port which connects the ACC-34AA, but you would lose Gate 3 style MACRO which provides more nodes at lower cost.
