EE242 is the base station for a network of up to 500 wireless transmitters for temperature, humidity and CO2.
With the integrated web server (no need for any additional software) the user can set up the wireless network via Ethernet interface. The measured data from the transmitters is available at EE242 on Modbus RTU and TCP/IP. Four of the measured parameters can be selected for the analogue outputs of EE242.

What is the difference between a 2 wire and a 3 wire current output?
Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
