3 Product Description
3.1 General
The EE431 duct and immersion sensor reliably measures the temperature (T) in air and liquids. It is optimized for
building automation, HVAC and process control. The measured data is available at the voltage or current output,
on the RS485 interface with Modbus RTU or BACnet MS/TP protocol and on the optional display. The analogue
output can be set to °C or °F. In addition, the EE431 features a wide choice of sensing elements for passive
temperature measurement.

3.3 Electrical Connection
EE431 features screw terminals for connecting the power supply and the outputs. Insert the cables into the
enclosure through the M16 cable gland.
NOTICE
It is important to make sure that the cable glands are closed tightly. This is necessary for assuring the IP
rating of the enclosure according to EE431 specification, as well as for stress relief at the screw terminals on
the EE431 board.
