2.4.7.1 Analog 0-10V or 4-20mA inputs
The WebdynSunPM has 4 analog inputs marked “Analog” used to measure current of between
4 and 20 mA or a voltage of between 0 and 10 V. Each analog terminal block has a power
output that can be used to power a sensor. The voltage delivered by this power output is equal
to the concentrator’s power supply voltage. The earth on each analog terminal block is
common.
Each analog input can be software configured to 0-10V or 4-20mA.
The concentrators analog/digital converters (CAN) have 12 bit resolution making possible in:
•
0-10 V mode : to have .578 mV resolution
•
4-20 mA mode : to have 5.578 µV resolution
To connect, power off the concentrator and the 0-10V or 4-20mA sensor. Take into
account the wiring information provided by the sensor manufacturer.
