The following items are provided by Samotics and are required to be installed in order to provide our service.
Data Acquisition Device (DAQ)
Data Acquisition Device (DAQ)
The DAQ collects analog data from the current and voltage sensors and converts it into a digital signal. The DAQ is supplied with power through an Ethernet cable (Power over Ethernet - PoE).
The QR code (underneath the Ethernet port) is required later in the installation process for commissioning of the DAQ in the SAM4 database.
Switch
Switch
The switch connects several DAQs to the gateway via a single Ethernet cable. At least one switch must be installed for each gateway.
The switch is powered via a direct connection with the power supply.
Gateway
Gateway
The gateway collects the data from (max 10) DAQs, processes this data, and sends it to the Samotics platform through a mobile 4G signal, Wi-Fi, or wired internet connection. The gateway is connected to the switch through an Ethernet cable.
Upon delivery, the gateway is already equipped with a bracket for placement on the DIN rail, and a SIM card in case 4G is chosen for the connectivity option.
Power supply
Power supply
The power supply adapter powers the complete SAM4 system. The adapters are calculated at a maximum of 75% of the power (60 W). One adapter can power three gateways (15.4 W per gateway) or one gateway and two switches with 10 connected DAQs. The adapters are installed on a DIN rail. If there is already an adapter present in the system, it is possible to use this adapter.
Notice The unit is regarded as permanently installed and shall therefore be provided with a switch or circuit breaker that is marked as such and located near the equipment.
Current sensors
Current sensors
The current monitoring sensors are placed at the secondary side of the transformer and connected to the DAQ.
Warning Use only sensors with approved reinforced insulation from the hazardous mains conductor.
Notice The wiring requirements for the current sensors are flammability V-1 or better, 2x cross-section between 0.75mm² - 2.5mm².
Feed-through terminal blocks (incl. fuse and end plate)
Feed-through terminal blocks (incl. fuse and end plate)
A fused test voltage can be easily branched using the 2-way fused terminal block with push-in technology. The terminal block has a swiveling fuse holder with a 2A fuse. The terminal blocks are mounted to a DIN rail. One end plate is used for every three terminal blocks, protecting the internal components of the blocks.
Notice Also includes the fuse and end plate. The provided fuse complies with the following characteristics which a replacement fuse must also fulfill: fast fuse 2A nominal current, 690 rated voltage, 20kA minimum breaking capacity.
Notice The wiring requirements for the voltage monitoring are: flammability V-1 or better, 600V, basic insulation, cross-section between 0.5mm² - 2.5mm².
Ethernet cables
Ethernet cables
The SAM4 system is delivered with Ethernet cables to connect DAQs to switches and switches to gateways. If these cables are too short or faulty, you can make new or longer Ethernet cables yourself.
Notice The SAM4 hardware is delivered with CAT 6 Ethernet cables (or higher).
Magnetic foot antenna
Magnetic foot antenna
For 4G and Wi-Fi reception, use the supplied magnetic foot antenna(s). With its 2.5-meter cable, it can easily be placed outside the control cabinet for better signal strength. Extension cables are available upon request.
SIM card M2M (optional)
SIM card M2M (optional)
In case 4G is chosen to connect to the internet, a SIM card is already installed in the gateway.
