Multifunction meters – 8 channels of 3 phases

Basic data

The TNM230 is a universal multifunction measuring device with 8 channels of three phases each.

Using one TNM230 energy and power meter can save the application of 7 other energy meters or multifunction meters, making the working environment more clear and space-saving, as the TNM230 energy and power meter covers the capacity of 8 energy meters or multifunction meters.
 
It has RS485 and TCP/IP interface with BACnet and Modbus protocols. The TCP/IP interface allows the meter to be operated and configured via a web browser. An indispensable aid for any energy management to display min. and max. values, as well as active and reactive power and all important measured variables.
