Attention: the upper power supply limits must not be exceeded, as this might cause serious damage to
the module.
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...).
POWER SUPPLY
The power supply is connected to terminals 2 and 3.
The supply voltage must be between:
11 and 40Vdc (indifferent polarity), or between 19 and 28 Vac.
The power supply source must be protected from any failures in the
module by means of a suitably sized fuse.
