Introduction
Main Functions
- Real‑Time Clock & Calendar Time‑keeping Function It is a dedicated hardware real‑time clock (RTC) module. It maintains accurate system date, time, minute, second, calendar and timestamp information for host industrial controller / industrial computer. Provides precise time reference for event logging, alarm time‑stamp, sequence‑of‑event recording and historical data tagging.
- Battery‑backed Non‑volatile Time Data Preservation Equipped with on‑board backup battery. It continues time‑counting when main system power is fully cut‑off. Time and calendar data will not be lost after power‑off or cabinet power cycle.More products: www.plcva.com
- Backplane Bus Time‑data Exchange Installed on host system chassis slot. Synchronizes time‑calendar data with main CPU via system backplane bus. Supplies timestamp data for controller event logs, fault records and process historical records.
- System Time Initialization & Synchronization Support Provides hardware time reference during host‑system power‑on boot‑up. Delivers baseline calendar‑time data to the main controller before software synchronization. Supports local time setting via host system software.
- Hardware Status Monitoring Detects backup‑battery low‑voltage condition. Reports battery‑weak fault status to host controller, reminds maintenance personnel for battery replacement to avoid time‑keeping failure.

Note: ZBX‑348 is EOL (End‑of‑Life) obsolete spare part. It cannot run independently; it must be inserted into matching legacy industrial host chassis. Original mass‑production has been discontinued, only used as aftermarket replacement spare component.

Applications
This clock calendar module is dedicated spare hardware for legacy industrial computer‑based automation control systems:
- Process industry control systems: Provide hardware timestamp for alarm events, fault logs and process historical data in power, chemical and pulp‑paper plants.
- Industrial monitoring & data‑acquisition equipment: Realize accurate time‑stamping for production data and event sequence records.
- Industrial maintenance & retrofit: Direct replacement for defective ZBX‑348 module on existing control chassis, restores real‑time clock and calendar time‑keeping function for host industrial controller.
- Legacy special‑purpose machinery control: Maintain continuous calendar‑time for old‑generation automated production equipment.
