Eliminates the chatter that occurs such when the contact input is turned ON/OFF.
Can discard the signal changes over the specified interval.
Input status indication through the LEDs of each channel function
When in operation: Illuminates in green when pulse input is detected
When overdriven: Illuminates in red when the input voltage exceeds the range
