MULTICAL® 603
8 Communication Modules
MULTICAL® 603 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.
8.1 Module overview

HC-003-40
Analog module 0/4…20 mA
HC-003-60
LON FT-X3 + 2 pulse inputs
HC-003-66
BACnet MS/TP + 2 pulse inputs
HC-003-67
Modbus RTU (RS-485) + 2 pulse inputs (In-A, In-B)
8.2 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.

Pulse input C
66 -
67 +
Pulse input D
68 -
If a module with pulse inputs is mounted in MULTICAL®, the meter is automatically configured for
pulse inputs. 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 can be
changed by means of the PC program METERTOOL HCW.
