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 Pulse, inputs (In-A, In-B)

HC-003-20 Wired M-Bus, inputs (In-A, In-B)
HC-003-21 Wired M-Bus, outputs (Out-C, Out-D)
HC-003-22 Wired M-Bus, Thermal Disconnect
HC-003-30 Wireless M-Bus, inputs (In-A, In-B), 868 MHz

HC-003-40 Analog outputs 2 x 0/4...20 mA
HC-003-43 PQT Controller
HC-003-50 Low Power Radio, inputs (In-A, In-B), 434 MHz
HC-003-51 Low Power Radio GDPR, inputs (In-A, In-B), 434 MHz
HC-003-66 BACnet MS/TP, inputs (In-A, In-B)
HC-003-67 Modbus RTU, inputs (In-A, In-B)
" The module requires that the meter is mains-supplied.
# The module requires an external power supply.
% The module requires a specific configuration in the meter, see the module data sheet for
details.

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.
Min. pulse duration is 30 ms. and max pulse
frequency is 3 Hz.
If a module with pulse inputs is mounted in MULTICAL®, the meter is automatically configured for
pulse inputs. Note that the meter factor (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 can be
changed by means of the PC program METERTOOL HCW.
