BMS (Building Management Systems) oversee building functions like security, lighting, and HVAC. Interconnecting diverse controllers demands a common protocol. CAREL's adaptable controllers connect seamlessly and support prevalent protocols including LonWorks®, Modbus®, BACnet™, and more.

The Fieldbus cards are used to connect pCO sistema family controllers via a serial link to Carel or third party devices, using standard or proprietary protocols, so as to acquire information and/or send commands and ensure efficient unit management. CAREL offers a wide range of add-on solutions (serial cards) to fit into the FieldBus slot on its pCO controllers, according to the required protocol.

CAREL's wireless gateways offer Bluetooth and Wi-Fi connectivity, bridging communication gaps where wired connections are impractical. Wi-Fi speeds up field device installation, while the Bluetooth gateway enhances interaction with APPLICA and CONTROLLA on non-wireless programmable controllers.

Supernode is a compact pCO sistema family controller designed to manage a high flow of information, thanks to its 6 serial ports, built-in display and a keypad that can be customised via software.
