Master clocks
Automatically synchronise a clock network to the same time base
The master clock is a programmer designed to transmit reliable, consistent time to a network of analogue or digital LCD and LED clocks.

Advantages of Bodet Master Clock
The master clock also programs bell systems, lighting, heating, air conditioning and access control across wired or radio (DHF) networks.
- Automatic time setting on all clocks.
- Identical time on all clocks at the same location.
- Automatic summer/winter time changeover.
- Offers multiple output protocols for time distribution (Impulse, Wireless, NTP, AFNOR, etc.).
- Available for wall mounting or rack fittings.
