The internal power supply voltage for the module's circuitry is carried out via the I/O bus
(provided by a communication interface module or a CPU). Thus, the current consumption from
24 V DC power supply at the terminals L+/UP and M/ZP of the CPU/communication interface
module increases by 5 mA per AI562.
The external power supply connection is carried out via the UP (+24 V DC) and the ZP (0 V DC)
terminals.
NOTICE!
Risk of imprecise and faulty measurements!
Analog signals may be distorted seriously by external electromagnetic influ-
ences.
Use shielded wires when wiring analog signal sources. The cable shield must
be grounded at both ends of the cable. Provide a potential equalisation of a
low resistance to avoid high potential differences between different parts of the
plant.
