MULTICAL® 62 • Water meter
5.1.2
M-Bus, type 67-00-20/27/28/29
M-Bus can be mounted in star, ring or bus
topology. Up to 250 meters can be connected
depending on the M-Bus Master’s power supply
and the total cable resistance.
Cable resistance
< 29 Ohm
Cable capacity
< 180 nF
The M-Bus network is connected on terminals
24 and 25. The polarity is unimportant.
M-Bus comes with pulse inputs.
5.1.3
Radio + pulse inputs, type 67-00-21/25/26/29
The radio module is used for wireless communication
via licence-free radio frequency and can be supplied with internal antenna or with connection for
external antenna.
For further information on radio we refer to Technical description for radio (5512-012 DK,
5512-013 GB).
The pulse inputs of this module are identical with the previously described pulse inputs.
Note:
Type 67-00-21 includes radio and router functions.
The RadioRouter module must be used with mains supply.
5.1.4
Prog. data RTC + 4…20 mA pulse inputs, type 67-00-22
The module has connection possibility for two pressure transmitters on terminals 57, 58 and 59
and can be adjusted for current reading or pressure ranges of 6, 10 or 16 bar.
The module is prepared for remote reading, data from meter/module being transferred to the sys-
tem software via the connected external GSM/GPRS modem on terminals 62, 63 and 64.
Furthermore, the module has two extra pulse inputs, VA and VB.
The module must be powered by 24 VAC.
5.1.5
Analog output, type 67-00-23
The module has two active analog outputs, which can be individually conigured at 0…20 mA or
4…20 mA. Furthermore, the outputs can be conigured for a speciic measuring value as well as
the required range scaling.
All output values are updated every 10 seconds.
The module must be mounted in MULTICAL® 62 and is powered by 24 VAC. Coniguration to be
carried out via the “Base module” menu of METERTOOL.
See installation instructions 5512-369 (DK-GB-DE).
