The Cello PoE Brick powers and manages any 24VDC modulating damper or valve actuator, through a single Ethernet connection. In addition to PoE, the Cello PoE Brick supports WIFI (2.4Ghz) and Bluetooth Low Energy (BLE) communications. Modulating actuators consuming up to 10 watts are supported.
In addition to modulating actuator control, the Cello PoE Brick supports a wide range of I2C and 1-Wire sensors from different manufacturers such as Melexis IR T sensors, Measurement Specialties (TE) T/H sensors, Omron pressure and T sensors, and Maxim T sensors.
The Cello PoE Brick can be controlled from the Cello cloud, or locally via any web browser or Modbus TCP client. The Cello cloud supports manual and scheduled modes, as well as automatic air balancing control.
Local control of the modulating actuator is achieved using proportional DAC (0-10V, 2-10V, or any voltage within the range) control with ADC position feedback.
The Cello PoE Brick works with any off the shelf PoE switch or injector which meets the 802.3af and 802.3af standards.
