1. General

       The PZ-K32 unit allows the simultaneous collection of 32 actives or passive switch signals. The unit is connected to upper computer with an RS485 interface and utilizes Polling for data exchange to reflect the switch status on a real-time basis. This unit can store the sequence of 2000 events (SOE information), and therefore can accurately indicate the time of the switch status changes.
