EDC-communication module

The EDC communication module (electronic data capture module) was developed for electronic, non-reactive scanning of all ZENNER water meters equipped with a modulator disc.

The EDC module variant with M-Bus interface and electronic pulse output is an add-on module for water meters for remote reading or for integrating meters into wired M-Bus networks or readout systems. The combined version of the two interfaces enables data transmission to two different users. The pulse output of the combination module is supplied ex works with mode U in accordance with ISO 22158.
