TRM 102 is a device, which allows for communication through Ethernet network (Intranet/Internet) with weather regulators ECL200/300, thermal energy meters and additional input-output modules. According to configuration, module is able to operate weather regulator, up to 6 energy meters and up to 10 additional input-output modules.
Features:
Communication with Danfoss regulators ECL200/300
Communication with meters in MBus protocol
Expanding with additional inputs-outputs
Graphical data presentation through WWW
Communication standardization for Modbus TCP protocol
Data registration in mass memory
Data sharing in CSV standard for MS Excel
Power supply: 10 ~ 30 Vdc.
The most important functions of TRM 102 are graphical visualization of processes in thermal centre, registering of centre operation parameters, registering of emergency situations, possibility of signalling of alarm states through sending email messages (easily converted to SMS), sharing of collected data for Excel spreadsheet, possibility of remote change of weather regulator parameters and remote control of pumps and actuators installed in thermal centre, all those functions are available through Internet Explorer browser.

Interfaces and protocols:
RS232 (protocol MBus).
RS232 or RS485 (service protocol ECL300 or Modbus RTU)
ECL200/300 regulator operation - bi-directional data exchange with regulator* (write/read). Form Ethernet side Modbus TCp protocol is available with operation of 16 concurrent connections with Modbus TCP masters. Data conversion from M-Bus meters**.
Functionality as for TRM102 version, plus additionally converter includes mini WWW server, allowing for viewing and controlling of regulator parameters though the Internet browser.
Functionality as for TRM102 version, plus additionally converter includes memory for data regstration. Registered data are available as *.csv* files through FTP server, built in the converter.
Converter with full functionality connects functions of TRM102-W and TRM102-D with the possibility of receiving of collected data through the Internet browser.
* communication is possible through the Danfoss service protocol or Modbus RTU after installation of ECA71 module
** connecting of MBus meters requires installation of MBus 10 type converter for RS232-MBUS standard.
