Landis+Gyr ET50 communication technologies are based on open standards which make it easy and reliable to use and ensures compatibility with future development. Landis+Gyr has a long and successful history in utilizing power line communication. The ET50 LV PLC communication is based on LonTalk® protocol and LONWORKS®. The four S0 inputs provide a simple and cost-efficient way to introduce devices into the AMR system and M-Bus is also widely used in metering devices. The ET50 M-bus interface offers a flexible way to collect district heating meter values with selection of 16 variables.
The Landis+Gyr ET50 can be installed on the terminal block of DIN compliant metering devices or to a wall with a mounting kit and it does not require an external power supply. The intelligent and automated installation process with Landis+Gyr Site Manager speeds up the implementation and eliminates human error. The concentrator automatically recognises ET50 devices that have been entered into its topology and establishes communication to the device.
The communication quality of Landis+Gyr ET50 can be monitored and reported precisely and the cumulative power cut duration and number of cuts is registered in the device. The ET50 offers flexible controls with two relays, week calendar and dynamic and direct controls. Also special street light control functions with adjustable delay are available. The Landis+Gyr ET50 meets strict environmental requirements. The device is made of recyclable materials and conforms to the RoHS directive. Also the packaging is made of recyclable cardboard.
