Electrical connection
The instruments are designed to operate with safety extra-low voltage
(SELV). When wiring up the instruments, the technical specifications
for those instruments should be followed. In the case of a sensor with
transmitter, as a rule, the transmitter should be operated in the middle of
the measuring range, since deviations can occur at the range limits.
The ambient temperature of the transmitter electronics
■
should be kept constant.
Current/voltage spikes from switching the power supply
■
on or off must be prevented by the customer.
Current consumption
35 mA + switch (7 mA each) + instrument with automatic zero
adjustment (20 mA)
0 ... 10 V output (10 mA), max. 80 mA
