Bosch B443 — Conettix 3G/HSPA Plug-in Cellular Communicator
The plug-in cellular radio for Bosch's Conettix communication platform. It carries its own SIM socket and clips onto a B450-M interface board to give a Solution 2000 or 3000 a cellular reporting path. Rated -10°C to 55°C at Environmental Class III under EN 50130-5.
Key Details
- Cellular reporting — A path to the monitoring centre that does not depend on the building's phone line or internet service.
- Onboard SIM socket — One built-in socket; supply a data SIM from the carrier with the best coverage at the site.
- Certified to EN 50130-5 — Environmental Class III, which matters where the installation has to meet a formal standard.
- Compact 50 x 93.5mm board — Fits inside the panel enclosure alongside the B450-M.
- -10°C to 55°C — Tolerates an unheated enclosure in a garage or plant room.
Where It Fits
Adds cellular backup to a Solution 2000 or 3000. It requires the B450-M interface — it does not connect to the panel on its own. For a Solution 6000, the CM368B or MY368AU are the equivalent and need no carrier board.
