Is it possible connect a Form A Digital Input on an ION7650 to read pulses from a 3 wire KYZ output?

A simple 3-wire KYZ output will transition from closing the K&Y (with K&Z open) to closing K&Z (with K&Y open).
The form A digital inputs on the ION7550 and ION7650 inject a current-limited 30V signal to detect when the contact is closed or open. By configuring the ION module to KYZ mode, it will now count each transition (either open or close) as a "pulse".

This will allow just one digital input connected to the either Y or Z and the digital input common connected to K.
