Power voltage must be in a range from 10 to 40 V (indifferent
polarity), from 19 to 28 V ; see also sectionINSTALLATION
NORMS.
Upper limits must not be exceeded, if it happen there could be
damagesformodule.
It is necessary to protect power source from possible module's
failure by fuse correctly dimentioned.

ELECTRICAL CONNECTIONS
For signals connection please use shielded cables; the equipment cable
shields must be connected to a preferential ground. It’s also a good rool
avoid to pass wires near power installation cables like transformers,
inverters, motors, induction ovens etc.
HOW TO INSTALL
Z109S-DI module is designed to be on a DIN 46277 bar, ininstalled
vertical position.
For working properly and long life, make sure that adequate ventilation is
provided for the module, avoiding placing raceways or other objects which
could obstruct the abat-vents.Avoid to install module over equipment that
generatesheat.

HEAVY WORKING CONDITIONS:
Heavy working conditions are:
High power voltage a ( > 30V / > 26 V ).
Input sensor feeded.
Use of output in impressed current.
When modules are installed side by side it may be necessary to
separate them at least 5 mm in the following cases:
Upper board temperature higher than 45°C and at least one of the
heavy working conditions verified.
Upper board temperature higher than 35°C and at least two of the
heavy working temperature verified.
OUTPUT
ACTIVE OUTPUT : use this connection when output loop is to be
directlyfeededfromZ109S-DImodule.
Loop power supply given by Z109S-DI module is protected against
shortcircuit.
Maxloadresistance600ohm.
PASSIVE OUTPUT : usethisconnection ifcurrentloop's powersupply
