Optional plug in communication modules:
- M-Bus module
- Radio module 868 MHz
- MODBUS RS485 module
It is designed for data reading via M-bus protocol and parameterization of the meter.
If meter is powered from internal battery - the total working time of serial communication interface
is limited up to 200 minutes per month (for protection of the battery against premature discharge).
Unused limit of communications are summarized. The interface is blocked after the expiration of a
limit and only after change of the hour, the new time limit of communications will be given (for 16
seconds for each next hour).
3.2.2 Pulse outputs
Pulse outputs: 2 (OB-normal mode, OD-test mode)
Type: open collector, permissible current up to 20 mA, voltage up to 50 V
Pulse duration: 100 ms – in the normal operating mode, 1.6 ms – in the test mode
Energy pulse output values:
Energy units kWh, MWh GJ Gcal
Pulse value of thermal energy 1 kWh/pulse 0.005 GJ/pulse 0.001 Gcal/pulse
Flow (volume) pulse output values:
Permanent flow rate, [q
p
, m

/h] 0.6 ... 6 10; 15
Pulse value [l, pulse] 1 10
For switching pulse outputs into pulse inputs two jumpers have to be set in the following positions
and meter has to be reconfigured by Userconfiguration SW (see chapter 6).

3.3 Supply voltage
Internal battery:
- Size AA, 3.6 V, 2.4 Ah, lithium battery (Li-SOCl
2
)
- Service life not less than 11 years
Mains power supply:
- 12 V…42 V DC or 12 V…36 V AC, 50/60 Hz, 10 mA max + internal backup
- Battery: size AA, 3.6 V, 2.4 Ah, lithium battery (Li-SOCl
2
) service life not less than 11 years (without
data reading via a digital interface) – for powering of the meter, when the external power supply is
turned off
- Mains supply 24V AC/DC module is mounted inside in the meter
