POWER SUPPLY
Connect the IDC10 rear connector to provide power supply to module.
The supply voltage must be between:
10 and 40V
(any polarity), or between 19 and 28 V .
dc
ac
The upper limits mus not be exceeded as this can seriously damage the
module
If the power supply source is not protected against overload, a safety
.
fuse of max. 2.5 A must be installed in the power supply line near the device.

USB
The module has a micro USB port on frontal panel for configuration and MODBUS-RTU parameters
communication.

Slot
Don’t force the insertion
of the IDC10 connector into the Z-PC-DIN bus.
The rear IDC10 connector of the module will be inserted on a free slot of Z-PC-DIN accessory.
In the figure you can see the meaning of the various pins of the rear IDC10 connector if you want to
provide the signals directly through this connector. The pictures
and
show how to

connect powersupply and RS485 COM1 port to the rear IDC10 connector.
In case of Z-PC-DINAL2-17,5 accessory use, the signals may be provided by terminal blocks.
The figure shows the meaning of terminals and the position of DIP-switch (present on each DIN rail
supports) for network termination (not used in case of Modbus network).
GNDSHLD: Shield to protect the signal inside the connection cables from electromagnetic
disturbances (recommended).
