Passive "open collector" pulse inputs,
outputs not potential isolated from each
other, data are separately cumulated in
different registers and are also stored on
the two accounting days.
Pulse value and the unit are configurable
for energy, water, gas or electrical meter
by a software tool

The optional M-Bus plug-in module is a
serial interface for communication with
external devices (M-Bus Repeater)
M-Bus according to EN1434
Open collector,
2400/300 baud, 3.6 V
The optional plug-in RS232
communication module is a serial
interface and permits data exchange with
the calculator. For this purpose a special
data cable is necessary
