POWER SUPPLY
ATTENTION!
The upper power supply limits must not be exceeded, as this might cause serious damage to the
module
Switch the module off before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations
(transformers, inverters, motors, induction ovens, etc...)
The power supply must be connected to terminals 20 and 21.
The supply voltage must be between:
10 and 40Vdc (indifferent polarity), or between 19 and 28 Vac.
19 – 28 Vac 50 – 60 Hz
10 – 40 Vdc
Maximum absorption 2 W
If the ZPCDIN accessory is used, it is not necessary to wire the power supply (nor the RS485 port) as it is
present in the IDC10 connector:
