3. Interface & Communication
4.1 IrDA
B12 VI Series are all equipped with an optical interface IrDA to IEC62056-21 as a standard.
In addition, one of the following options can be ordered for remote output.
4.2 M-BUS
Cable: connected with galvanic isolation
Voltage: 50V max.
Current: M-Bus loads
Addressing: primary or secondary
Note: A higher frequency is not allowed and may result in meter malfunction!
Data transmission in the compatibility mode (= standard, one data frame) or in the full mode
(3 data frames) possible.
If the meter is equipped with
“
M-bus
”
, it is delivered with a two wire cable, which can be
lengthened with a cable 2 x 0.75mm2 (put a distributing box). Pay attention to the proper
polarity in case of the pulse output. If the meter is read out via M-bus, the allowed mean
frequency of reading must not be exceeded. Any more reading is not allowed and may
result in a damage to meter.
The M-Bus or pulse variant of the meter is supplied with a 2-wire cable with wire end
ferrules.
