The modules are designed for data collection from battery-powered WACO system modules and data conversion to the M-Bus communication protocol.
The WM868-SJ-RK modules (hereinafter “collection units”) are designed to collect data from battery-powered modules that operate in the active communication mode, which means that to save batteries, they are not permanently “receiving” but transmitting data actively, at set intervals, or spontaneously, based on an alarm event. The bus unit captures and acknowledges messages from the battery modules and stores them in its memory so that it can be transmitted in passive mode (on request) to the master of the master M-Bus. The bus unit therefore converts the communication mode from active to bus (passive). Through the bus unit, devices with pulse and analog output can also be connected to the virtual bus so that they appear to the bus master as a device with an M-Bus data output.
The WM868-SJ-RK module is a bus unit without a physical line interface, designed for wireless connection of WM868-SI / SA, WM868-TI / TE, or WM868-SEA / MDA / MDB modules to the M-Bus / RS-485 virtual radio bus .
Radio protocol converter without physical interface. The module is part of the WACO bus system. It is used for data collection from consumption meters, sensors and sensors of the WACO system and data conversion into the M-Bus communication protocol format.
The module with a transmitting power of 25 mW requires power supply from an external source (9 ÷ 24) V. The module is adapted for mounting on a DIN rail and is designed for indoor use (IP-20 protection).
The modules are most often used in applications of M-Bus systems, which are widely used especially in the field of remote reading of consumption meters (“metering”, “smart metering”).
