Wired Master Slave Clock System

Electromed’s Wired Master-Slave Clock System offers precise, synchronized timekeeping for complex indoor environments like offices, hospitals, and buildings with multiple closed rooms. The Master Clock, featuring GPS, serves as the primary time source, which then sends accurate time data to slave clocks via RS485 connections, ensuring unified time displays throughout the facility.

The RS485 wiring enables consistent time synchronization across multiple clocks without relying on a clear line of sight. This makes it ideal for settings with physical barriers, as the RS485 signal remains unaffected by walls and floors. The master-slave setup ensures every clock is in sync with the GPS time, providing consistent and accurate time displays across all rooms and hallways.

Easy to install and maintain, Electromed’s RS485 system provides reliable time synchronization without frequent adjustments. It’s designed for facilities needing dependable timekeeping in various rooms, enhancing coordination and punctuality across departments. With Electromed’s RS485 clocks, organizations benefit from seamless, synchronized time across all spaces, promoting smooth operations and productivity.

When to Use Different Clock Systems
ParameterStandalone GPS ClockWired Master Slave Clock SystemWireless Master-Slave Clock System
Best UseIdeal for locations with open sky access, requiring only a single, standalone clock.Best for buildings with physical barriers and closed rooms, providing stable synchronization through wired connections.Perfect for flexible clock positioning in large spaces with minimal infrastructure.
InstallationNo wiring or master clock dependency; each clock operates independently with GPS synchronization.Requires RS485 or similar wiring for stable communication across multiple clocks.Requires only a power source for each clock, with the master clock wirelessly connecting to all slaves.
AdvantagesExcellent for outdoor setups with accurate timekeeping, independent of a master clock.Delivers consistent, synchronized time across multiple clocks connected to a central master clock.Flexible and scalable, with easy setup in large or dynamic spaces requiring synced time displays.
