12 unipolar optical isolated digital inputs for 90-125 VDC The module is arranged in two sections of 6 inputs. All inputs are 2 wire with separate common for each single input. Each input channel is isolated from each other and electronics.
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.
