20 Digital input (10-30 VDC) Module-DI20A

Quick Information

Digital Input module with 20 bipolar optical isolated digital inputs for 12..24 VDC. The module is arranged in two sections of 10 inputs, with 2 common terminals for each section. Each section is isolated from each other with 2KV and to electronics. Input 0.. 9 and 10-19 provides counters, with up to 100 Hz counting frequency @ 50% duty cycle.

A user programmable debounce filter, in 1 ms units, is provided for each digital input, to filter out noise or mechanical relay bounce. This could also be used in combination with software counters, in case a low frequency mechanical contact is used for counters.
In short The DI module is what you need. Rugged, fast, and a fair price tag to match it all
