The U1602 micro-summator is used as a PC adapter or a LON interface for the ECS-LAN, and is not equipped with its own display or control elements.

All relevant energy and power consumption data are acquired by 64 processing channels over defined periods of time at a programmable interval, and are stored to memory as load profiles along with corresponding maximum values.

Up to 63 U168X electrical energy meters can be connected to the U1602 micro-summator via the electrically isolated LON interface. Converters can be used for digital and analog input signals.

Two RS 232 interfaces (115kBit/s) allow for communication with external devices such as PC, report printer, modem or radio controlled clock for system time synchronization. Parameters configuration and data analysis are accomplished at the PC with ECSwin.

Summators can be interconnected over great distances with the multi-master compatible ESC LAN which assures unrestricted access to all network user data. Thanks to integrated high level intelligence and the customized ECL programming language, the summator is also suitable for customer-specific, decentralized solutions as a data logging, monitoring and optimization device.
