USE OF THE Z-PC-DINAL ACCESSORY
Do not turn the module upside down
and
do not force the insertion
of the IDC10 connector on
the Z-PC-DIN bus.
The rear IDC10 connector of the module must be inserted on a free slot of the Z-PC-DIN bus.
The illustration shows the meanings of the various IDC10 connector pins if signals are to be sent
via them directly.
Fig. 1 c
and
Fig. 1 d
show the power connection and RS485 COM1 port on the IDC10.
ELECTRICAL CONNECTIONS
CAUTION:
On first start-up the module must be supplied without any interruptions for at
least 72 hours to charge the internal batteries.
Switch the module off with the PS1 button 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...)
•
POWER SUPPLY
The power supply must be connected to terminals 2 and 3. The supply
voltage must be between: 19 and 40Vdc (indifferent polarity), or between
19 and 28 Vac.
The upper limits must not be exceeded in order to avoid serious
damage to the module.
The power supply source must be protected from any module
malfunctions using appropriately-sized safety fuses.
•
ANALOGUE INPUTS
Voltage
Active sensor current (4 wires)
Passive sensor current (2
wires)
The module has two
analogue inputs that
can be configured via
software as voltage
or current. For the
configuration
software, see the
user manual.
