Serial outputs
USB with Mini-USB type connector (cable
CP31
)
RS485 with
MODBUS-RTU
protocol (HD35APS only)
Ethernet connection
Only in HD35APW model. Permits (if the Internet
connection is available) sending alarm
and
the recorded data via
, to an
FTP
address or to
an HTTP server (
Cloud
). Allows the
MODBUS TCP/
IP
protocol.
Wi‑Fi connection
Only in HD35APW model. Permits (if the Internet
connection is available) sending alarm
and
the recorded data via
, to an
FTP
address or to
an HTTP server (
Cloud
). Allows the
MODBUS TCP/
IP
protocol.
GSM/GPRS connection
Only in HD35APG and HD35AP3G models. For
sending alarm
or
SMS
and data via
, to
an
FTP
address or to an HTTP server (
Cloud
). Allows
the
GPRS TCP/IP
protocol.
3G connection
Only in HD35AP3G model. For sending alarm
or
SMS
and data via
, to an
FTP
address or
to an HTTP server (
Cloud
). Allows the
3G TCP/IP
protocol.
Internal memory
The number of samples that can be stored depends
on the type of data loggers connected. The capacity
is 226,700 samples if all the data loggers record 7
quantities.
LED indicators
Presence of external power supply, battery charge
level, RF communication status.
Working temperature and
humidity range
-10…+60 °C / 0…85
%RH not condensing
Housing
Plastic material
Dimensions 135 x 86 x 33 mm (excluding antenna)
Weight
200 g approx. (including battery)
Installation
Wall mount support (
supplied
) for removable
installation or flanges (
optional
) for fixed installation
(*)
The connection of the SWD06 external power supply is necessary if the Ethernet, Wi-Fi or GSM/3G transmission is used.
(**)
The intensive use of the GSM/3G transmission can significantly increase the power consumption and reduce the battery life.
