Type 67-06: RTC + 66-C
compati pulse outputs
The top module makes MULTICAL® 601 data
compatible with MULTICAL® 66-C making it
possible to use many of the previous base modules
for MULTICAL® 66-C in MULTICAL® 601 too.
Furthermore the top module has two pulse outputs
for energy (CE) and volume (CV) respectively. The
pulse resolution follows the display (determined in
the CCC-code). E.g. CCC=119 (qp 1.5): 1 pulse/kWh
and 1 pulse/0.01 m
3
. The pulse width is 32 ms.
The pulse outputs are optoinsulated and stand
30 VDC and 10 mA.
Type 67-07: RTC + M-Bus
M-Bus can be connected in star, ring and bus
topology.
Depending on the M-Bus Master and the cable
length/cross section, up to 250 meters can be
connected with primary addressing, and even more
if secondary addressing is used.
Cable resistance in network:
<
29 Ohm
Cable capacity in network:
<
180 nF
The connection polarity of terminals 24-25 is
unimportant.
Normally the primary address consists of the last
digits of the customer number (000-250), but it
can be changed via the PC program METERTOOL.
Type 67-08:
RTC + hourly data pulse outputs
This top module has two configurable pulse
outputs, which are suitable for volume and
energy pulses for heat meters, cooling meters and
combined heat/cooling meters.
The pulse resolution follows the display
(determined in the CCC-code). E.g. CCC=119
(qp 1.5):
1 pulse/kWh and 1 pulse/0.01 m
3
.
The pulse outputs are optoinsulated and stand
30 VDC and 10 mA.
Normally energy (CE) is connected to 16-17 and
volume (CV) to 18-19, but other combinations can
be selected via the PC program METERTOOL which
is also used for selecting pulse widths 32 or
100 ms.
Furthermore, the module includes a hourly data
logger.
