Without taking into account the load at the 12V and 7.5V power outputs.
2
If all inputs are configured as counting and the 12V and 7.5V power outputs are turned off.

When operating at a temperature not higher than 0°C, with a stable communication signal, in the connection mode 3
times
a
month. Battery service life depends on a number of factors, including operating temperature, type of connection and frequency
of connections.
ATTENTION
! Increasing the polling frequency results in a shorter battery life.
