Type 67-07: RTC + M-Bus
M-Bus can be connected in star, ring and bus
topology. Depending on M-Bus Master and cable
length/cross section up to 250 meters with primary
addressing can be connected, and even more
using secondary addressing.
Cable resistance in network:
<
29 ohm
Cable capacity in network:
<
180 nF
The connection polarity of terminals 24-25 is
unimportant.
Unless otherwise stated in the order, the primary
address consists of the last three digits of the
customer number, it can be changed, however, via
the PC program METERTOOL.
Type 67-08: RTC + pulse output for CV + hourly
data logger
This top module has configurable pulse output,
which is suitable for volume pulses for water meters.
The pulse resolution follows the display (fixed in
the CCC-code). E.g. CCC=419 (Q
3
= 1.6 m
3
/h): 1
pulse/0.01m
3
.
The pulse outputs are optoisolated and withstand
30 VDC and 10 mA.
Normally volume (CV) is connected on 18-19, but
other combinations can be selected via the PC
program METERTOOL, which is also used to select
either 32 or 100 ms. pulse duration.
The module also comprises an hourly data logger
including registers as daily logger.
Type 67-0B: RTC + 2 pulse outputs for CV + prog.
data logger
The RTC and pulse output functions of this top
module are identical with the functions described
for top module 67-08.
The top module is prepared for use in a Kamstrup
radio network together with the RadioRouter
base module 67-00-21-000-3xx, read data being
transferred to the system software via the network
unit RF Concentrator.
