6.3 Hardware
The LOGBOX SE is based on single board design with minimal dimensions, weight and power consumption.
▲The original model with 2G GPRS modem
▲The 2019 model with 4G GSM modem
Thanks to clear layout the user can easily connect relatively large number of sensors. For better access to input
connections, connectors are divided by two or three and removable.
The mounting plate can be used to connect the LOGBOX SE to a mast of 45 mm or smaller.
Unused cable glands are closed with a plug.
For permanent installation it is possible to use four screws
The LOGBOX SE board has the following components and connectors:
Fig.3 Description of major parts
SD memory card – any SD memory card larger than 128MB can be used. The card is used only for data storage and is not
intended for more manipulation (deleting or other operations). The unit comes with an industrial grade 512MB FAT
formatted SD card.
GSM SIM card holder – this will take your full-size SIM card which must have appropriate internet data services.
⌀
4mm for fixing, while retaining IP65 class protection.
Lithium battery, CR2032 - reserved for real time clock.
During normal operation the RTC is powered by the available power supply.
Off - On switch – small switch for turning the LOGBOX SE off (sleep except real time
clock). It is used when exchanging the SD card or when the data logger is not used.
EXC jumper – this jumper offers excitation for Pt-100 sensors. It connects a 3.9kΩ
resistor from the 2.5V reference voltage to AIN9+. If no Pt-100 is used, do not connect
it.
BATT MNG jumper - this jumper is used when your power supply is a 12Vdc solar panel
or charger input (5Vdc to 12Vdc). If this jumper is removed, the only power
input is POWER and the control circuitry of the charger is disconnected. This leads to
minimum power consumption during operation.
