Analog Input Module for LON

The U1661 analog input module is used for the connection standard signals to the LON interface at U1601, U1602 and U1603 summators.

This task has traditionally been accomplished through the use of a universal input directly at the summator. If all of the inputs are already in use, or if the distance between the signals and the summators is too great, they can be connected to the summators via the analog input module.

The module provides a summated value for each channel (analogous to the energy value for energy meters), as well as an instantaneous analog value (corresponds to instantaneous power for energy meters).

The module expands the number of available inputs for the U1601 summator and the U1603 mini-summator. External analog inputs are only possible for the U1602 micro-summator with the analog input module.
