Digital Clock Systems

Ace Instruments manufactures Digital Clocks suitable for all pharmaceutical and industry applications. The clocks are available in standalone and synchronisation versions. Synchronised clocks are especially suited for pharmaceutical industry following USFDA norms as per 21 CFR Part 11 for Good Time Management Practices. The synchronised clocks can have up to 120 slaves to 1 master and can be connected to the master clock via a 2-core communication cable on RS 485 Modbus multidrop network and the master clock time is synchronised with all the slaves. All the clocks in the synchronised clock network show the exact same time right up to the seconds. Time is accurately maintained even in the case of power cut by virtue of built-in battery. The master clock is a 2" or 4” high super bright 7-segment display panel with 6 displays, 2 each for hours, minutes and seconds. The slave clocks have a 4" high super bright 7-segment red LED display with exceptional depth and clarity for visibility over a long distance. The slave clocks are placed across the plant and can be at a maximum distance of up to 1200 mtr (1.2 km) and yet show accurate synchronised time, same as the master clock. Master clock can be provided as a GPS (global positioning satellite) clock with time accuracy of ±1 second. Thus, all slaves communicating with master clock over RS 485 will also show the same GPS time across the network. The clocks communicate over Modbus RS485 communication network. Optionally wireless communication is also available, thus avoiding expensive cabling and manpower wastage. PC time synchronization with related software is an option wherein the PC time is maintained across the network over Ethernet.
