- Monitoring of Mains
Frequency
- Pre-connected GPS167 or PZF509 as
Reference
- 2 analog outputs (time deviation and/or
frequency deviation)
- Serial RS232 Interface
- Calculation of Time based on the Local
Frequency
|
|
A preconnected reference is necessary that provides a
high accuracy 10MHz clock, a serial time string and a
PPS (pulse per second). The accuracy of the
measurements is derived from these signals.
The module calculates the frequency as well as the
time, based on the mains frequency. The time
deviation (TD) is the difference of this calculated
time (PLT) to the reference time (REF). This time
deviation as well as the frequency itself is sent out
via serial interface or is beeing converted to an
analog voltage output provided by a DAC.
The board is equipped with a flash memory and a
bootstrap loader which allows to update the systems
firmware via serial port.
Please note that the display shown above is not
included, see DU35K product page
