E+E EE650 Specifications

EE650
The EE650 air velocity transmitter is dedicated for accurate and reliable measurement in building automation and ventilation applications.
The device employs an innovative air velocity sensing element, which operates on the thermal anemometer principle and is manufactured by
E+E in state-of-the-art thin lm technology. Due to its innovative design,
For the EE650 with analogue output, the measuring range 0-10/15/20 m/s
(0-2000/3000/4000 ft/min), the output signal 4-20 mA or 0-10 V as well as the
response time 1 or 4 seconds are selectable by jumpers.
The bus address, the termination resistor and the response time of the Modbus RTU and BACnet MS/TP versions can also be easily set on the electronics board.
The enclosure design and the mounting ange included in the scope of
supply allow for fast and easy installation.
With an optional adapter cable and the free EE-PCS product conguration
software, the user can adjust the EE650, set the output scale and select the interface parameters.
