Module-DI20B

Back
20 bipolar optical isolated digital inputs for 30..60 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.
