M855 Analogue Clock Driver Unit
M855 Analogue Clock Driver Unit provides the capability to drive a large number of slave clocks when used in conjunction with a master timing system.
Features
- Complementary product for use with any TFS Master Clock or Timing System
- Provides two outputs of reverse polarity impulses to drive standard analogue clocks.
- Drives both Standard Impulse Analogue Clocks and Intelligent Analogue Cocks
- 2U high 19 inch rack-mountable enclosure
Time data is output together with the reverse polarity impulses, allowing intelligent units to interpret the data and display the correct time. By this means, a single clock circuit can be used to drive a variety of clock types, thereby offering an economic installation for the complete clock system.
The unit provides two outputs, each of which is capable of driving approximately 100 indoor and outdoor analogue clocks. Through the provision of two outputs, the unit offers the potential for each of the two circuits to be set to a different timing requirement.
The required pulse interval is configured using the menus on the Master Clock or Timing System, and once per second, once per 30 seconds or once per minute intervals are available. Through the use of two such circuits, one unit is capable of satisfying the need for driving both hours, minutes and seconds and hours and minutes only clocks.
The Analogue Clock Driver Unit can be used with the following products:
