Communication

Communication module

The communication modules are connected via a 6-pole reaction-free plug, enabling them to

be installed or replaced at any time.

Compliance with ESD regulations must be ensured.

1 Module 1 2 Module 2

The UH50.. meters are equipped with an optical interface as standard. Also, up to 2 of the

following communication modules can be used for remote readout:

Pulse module WZU-P2

M-bus module WZU-MB G4

M-bus module with 2 pulse inputs WZU-MI

Analog module WZU-AM

BACnet/Modbus module WZU-485E-BAC, WZU-485E-MOD

RF module, 868 MHz WZU-RF, WZU-RF-EXT

GPRS module WZU-GPRS, WZU-GPRS-ANT

LoRaWAN module WZU-LR, WZU-LR-EXT

NB-IoT module WZU-NB-IoT-EXT

These modules have no impact on consumption metering and can therefore be replaced at

any time without having to destroy the security seal.

Within 30 seconds after mounting (in case of the analog module up to 2 minutes), the meter

automatically detects the module used and is then ready for communication or for delivering

pulses.

The type of module used can be displayed within the service loop (loop 4) based on the dis-

play parameters.
