MULTICAL® 803 & ULTRAFLOW®
9 Communication modules
MULTICAL® 803 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.

HC-003-67
Modbus RTU, inputs (In-A, In-B)
HC-003-80
2G/4G Network
HC-003-82
Modbus/KMP TCP/IP, inputs (In-A, In-B)
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.
65 +
Pulse input A
66 -
67 +
Pulse input B
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.
