8 OUTPUT
The output consists of:
•
Frequency output MP103 card
•
Analog output MP103 card
•
Relay outputs MP103 card
•
Analog outputs AD card
• Digital outputs AD card
•
Modbus communication
8.1 Frequency output MP103 card
Frequency output:
- Maximum output range is software adjustable 1 – 2000 Hz
- 12V/24V / open-collector selectable by card jumpers
- There is one output value but there are two physical outputs, these can be phase-shifted 90°/180°
selectable by card jumper to simulate a turbine output for pulse fidelity and integrity check.
The resolution of the frequency output is max 0.016% of the output value. The resolution mentioned is
for a static output value. In practice, the output resolution will be averaged because of the variations in
signal. Over a period of time with different output values the resolution will not be an issue.
The most likely frequency output is the proces volumetric flow (default).
•
The frequency output function can be disabled/enabled in the Initialisation file: HSET0300.ufp
section 3
• The frequency output can be configured in the Initialisation file: CLNT0300.dat section 5
•
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)
