The AnDi is able to supply the sensors with power.
Each of the four measuring inputs and therefore each sensor builds up a separate
M-Bus slave. The user can program special primary and secondary addresses for the input
channels. This configured data is saved permanently into an EEPROM.
The AnDi4 can be mounted either on a wall or a DIN rail according to DIN-EN 50022. The
device needs a regulated power supply of 24VDC.
