7.3 Frequency inputs MP103 card
There are 2 frequency-input channels.
The MP103 card itself can only handle TTL signals. With optional signal converters/barriers a non-TTL
input signal can be converted into a TTL signal.
The used crystal oscillator properties are:
Stability 100 ppm over an operating temperature range of 0 –70°C.
Frequency measurement (option on channel 1 and 2):
The frequency-input range is 1-5000 Hz.
The frequency measurement is 24 bit. Multiple pulses are counted over a period of time.
Each frequency measurement takes approximately 8 seconds.
The function is to measure the density input from a Solartron/Sarasota densitometer.
Pulse counter (option on channel 1 only):
The input range is 0-5000 pulse/sec.
The pulse counter is 32 bit. Every 35 ms the counter is read. The counter can reset on demand.
It is used for the pulse input from an external flow meter.
Note that the two options are also embedded in the hardware, so depending on the used chipset for
channel 1 the option is available.
• The Frequency input function can be disabled/enabled in the Initialisation file: HSET0300.ufp
section 3
•
The Secondary input parameter can be set in Initialisation file CLNT0300.dat section 9 and 11.
•
The signals can be checked on value in the service window IO
•
Monitoring is also possible by its calibration program (see Manual: ALTOSONIC V UFP
Calibration and Verification I/O)
