Non-regulated DC voltage b10 and +18 VDC is sufficient
for the power supply of the datalogger
COMBILOG 1020
. The in-
put is protected against excess voltage and current and against
reverse polarity. The power consumption remains approximately
constant over the total voltage range, due to the integrated
switching controller.
Due to its low current consumption (max. 70 mA at 12 VDC) the
datalogger 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, together with the bus
line, if required.
In order not to charge the datalogger’s supply voltage unneces-
sarily, a separate power supply for sensors with a large current
requirement is recommended.
3.7 Bus
Connection
In general the datalogger is connected to the bus by applying the
signal leads A and B of the incoming bus cable and A' and B' of
the outgoing bus cable together to one terminal on the module
(figure 3.3).
