E+E EE451 Specifications
EE451
The EE451 wall mounted sensor measures reliably the
temperature (T) indoors and outdoors, is optimized for building
automation, HVAC, process control and enables weatherdependent temperature regulation.
Analogue, Digital and Passive Outputs
The T measured data is available on the voltage or current output,
as well as on the RS485 interface with Modbus RTU or BACnet
MS/TP protocol. In addition, EE451 features a wide choice of sensing elements for passive T measurement.
Easy Installation
The compact and robust enclosure allows for easy and fast installation and unbiased detection of ambient temperature.
Configurable and Adjustable
An optional adapter and the free EE-PC Product Configuration Software facilitate the setup and adjustment of the EE451.
