AIC - Model PM4-RTC -Real Time Clock Monitor
The real time clock monitor, PM4-RTC, is a highly visible and versatile indicator with a selection of display options. The clock may be set to display in 24 or 12 hour format. User selectable display formats are:
- Hours.Mins e.g. 1@22
- Hours.Mins.Secs - 6 digit model e.g. 0*5*30
- Days e.g. 364
- Day.Month e.g. 0*11
- Day.Month.Year - 6 digit models e.g. 2*1!12
- Month.Day e.g. 1!07
- Month.Day.Year - 6 digit models e.g. 1!2*12
Clock synchronisation may be via an internal clock chip, 50Hz or 60Hz mains synchronisation, optional high accuracy 10MHz crystal or optional GPS satellite transmission.
The clock circuitry is backed up by battery which means that, in the case of power failure, the time does not need to be reset when power is re-applied to the display.
Each instrument is supplied with one control/alarm relay (standard). Extra relays and other outputs are available as options. The versatile alarm functions allow up to 32 day/time setpoints to be programmed e.g. a relay can be set to operate on Monday to Friday only at 08.30 and 16.30.
