MULTICAL® 403

9 Communication modules

MULTICAL® 403 can be extended by a wide range of extra functions by means of communication
modules. Below, pulse inputs/outputs and module types are briefly described.
Note: Before replacing or mounting modules, the supply to the meter must be switched off. The
same applies for mounting of an antenna.

9.1 Module overview

MULTICAL® 403 communication modules
Type No. Description
HC-003-10 Data + 2 pulse inputs (In-A, In-B)
HC-003-11 Data + 2 pulse outputs (Out-C, Out-D)
HC-003-20 M-Bus + 2 pulse inputs (In-A, In-B)
HC-003-21 M-Bus + 2 pulse outputs (Out-C, Out-D)
HC-003-30 Wireless M-Bus, configurable, 868 MHz + 2 pulse inputs (In-A, In-B), internal or
external antenna.

9.2 Pulse inputs

Pulse inputs A and B are used for connection of
extra meters with either Reed-switch output or
passive electronic pulse output.
Minimum pulse duration is 30 ms, max. pulse
frequency is 3 Hz.
If a module with pulse inputs is mounted in
MULTICAL® 403, the meter is automatically configured for pulse inputs. Please note that the pulse
figure (litres/pulse) must match the extra water meters and the configurations of inputs A and
B. After delivery the configurations of pulse inputs A and B (config FF and GG) can be changed by
means of the PC program METERTOOL HCW.

9.3 Pulse outputs

Pulse outputs for energy and volume are
made with darlington optocouplers, the pulse
outputs are available on a number of the
communication modules.
Max. voltage and current of the outputs are
30 VDC and 10 mA respectively.
When a module with pulse outputs is mounted in MULTICAL® 403, the meter is automatically
configured for pulse outputs. The pulse duration is ordered at 32 ms. or 100 ms. After delivery the
pulse duration can be changed by means of the PC program METERTOOL HCW.
The resolutions of the pulse outputs always follow the least significant digit displayed for energy
and volume respectively.
