To buffer the bus voltage. If a complete mains failure
occurs, an external lead gel battery with a voltage
of DC 12 V (SELV) can be connected to the
REG power supply for buffering. The lead gel battery
is recharged or maintained in its charged
state by integrated charging electronics.
A binary input can be connected in order to register
the operational status.
For installation on DIN rails EN 50022. A data rail
is not necessary.
