Non-regulated DC voltage between +10 and +30 VDC is suffi-
cient for the power supply of the data logger COMBILOG 1022.
The input is protected against excess voltage and current and
against reverse polarity. The power consumption remains ap-
proximately constant over the total voltage range, due to the in-
tegrated switching controller.
Due to its low current consumption (max. 110 mA at 12 VDC)
the data logger can also be remote-fed via longer lines. Several
data loggers can be supplied parallel within the admissible
voltage range, considering the voltage drop in the lines. The
supply lines can also be installed in one common cable, togeth-
er with the bus line, if required.
In order not to charge the data logger’s supply voltage unne-
cessarily, a separate power supply for sensors with a large cur-
rent requirement is recommended.
