Connections devices
The GWNET network switch connects the temperature lines. Network controller GWAB connects to network switch GWNET, or several network controllers GWAB.
The GWCB connection unit connects the temperature lines, or several connection units, to form a single system. Each GWCB primary unit requires a 5VDC power supply.
Network switch – GWNET
Network switch GWNET connects up to four temperature lines. A maximum of four GWNET can be connected in series per input on a GWAB network controller. The connection is made with signal cable according to a specific specification. ATEX and IECEx approved.
Network controller – GWAB
A GWAB network controller has four inputs for up to four GWNET network switches connected in series. A total of 16 temperature lines per input and a maximum of 64 temperature lines per GWAB. Up to seven GWAB can be connected in series. The connection is made with signal cable according to a specific specification. ATEX and IECEx approved. Control via web or Modbus.
Connection unit – GWCB
The GWCB connection unit has eight inputs for either temperature lines or additional GWCBs. The device is prepared for use as a primary device (master) or secondary device (slave). Up to four GWCB primaries can be connected in series, and each primary unit can connect up to eight GWCB secondary units. A total of up to 256 temperature lines can be connected to the system. The connection is made with signal cable according to a specific specification. When the device is used as the primary device, 5VDC is required. Secondary units are powered by the primary unit. CE approved. Control via Grain App, web, or Modbus.
Connection unit – GWCB Plug&Play
The GWCB connection unit has eight pre-terminated inputs for either temperature lines or additional GWCBs. The device is prepared for use as a primary device or secondary device. Up to four GWCB primaries can be connected in series, and each primary unit can connect up to eight GWCB secondaries. A total of up to 256 temperature lines can be connected to the system. Connection is made using preterminated cable in specified lengths, according to a specific specification. When the device is used as the primary device, 5VDC is required. Secondary units are powered by the primary unit. CE approved. Control via Grain App, web, or Modbus.
Power supply unit – GWCB / CWCB Plug&Play
The GWCB power supply unit is powered by 230VAC and delivers 5VDC. The device is available for both the GWCB and GWCB Plug&Play connection units.
Connection device – Grain App
The Grain App connection unit connects to GWCB and enables data transfer to the cloud, where the information is visualized in the Grain App.
The unit is available for both GWCB and GWCB Plug&Play, as well as with a 5VDC power supply for the primary unit.
