Operating Manual
Important:
Connecting voltages higher than 3 Volts will damage the device.
7.5.7 Pulse Count - Voltage signals >3Volts
If the loggers YL-M41/42 and YL-M90 are used for pulse counts with a signal between
3V and 24V
the YY-CP
connection cable will be required. Operation with other cables
may cause damage.
With both asynchronous and synchronous signals a pulse is counted on the
rising edge (from low level to high level).
This connection can be configured in
LoggerSetup/SensorSlot
- SlotMode:
Frequency [Hz].
Important:
Connecting pulse inputs with a voltage greater than 24 Volts will
damage the device.
7.5.8 Voltage - GND reference signals (max 10V)
Applications:
standard analogue levels of industrial transmitters, etc.
This mode is suitable for measuring voltage signals between 0-10 Volts. This signal
needs to be connected with the YY-CU cable. Input with another cable may cause
damage to the device and mismatched readings.
The software allows selection of the input ranges 0-1V/ 0-2,5V / 0-5V / 0-10V (or freely
selectable between 1-10V). Input impedance in this mode is 100 KOhm.
