Product Description

Be careful:This module is MBUS slave module,Not master module!!

Be careful:New module Green PCB!!!!!

USB to MBUS slave module, master slave communication debugging, no spontaneous self collection!

USB turns MBUS from module to MBUS master and debug from module communication. This module connects the computer through USB interface. Through this module, the module is debugged from the module to the main module, and the chip is FC722 from the machine chip!The integrated chip FC722 is different from TSS721A without spontaneous self collection, and has lower bus leakage current compared with discrete device FC722.Analog slave machine (water heat meter, etc.) communicate with main equipment, and monitor MBUS bus.The module MBUS signal is completely isolated from the USB signal. There is no need to worry that the MBUS high level will damage the computer USB interface. MBUS signal part of the circuit from the MBUS bus power, nothing to do with USB!The characteristics of this product: 1. Fully consistent with M-BUS international standards and national standards2. Bus current 200uA - 3mA continuous3. The bus voltage 12V-42V can be adapted4. Enhanced 5V, 3.3V steady voltage output5, 300 - 9600BPS communication rate6. Support UART, high stability

The main source from the intelligent home control network application is commissioned

Simulated fire alarm and linkage network application of the main network application

Mock the main source from the central air conditioning control system application

The main source from the network application of the simulation of intelligent sensor network

Master-slave docking test

MBUS Introduction:

The meter bus (MBUS) is a new bus structure. The main features of MBUs are two non-polar transmission lines to simultaneously power and transmit serial data, while each sub-station (confirmed in different ID) is connected in parallel on MBus bus. . When MBUS is used in the energy consumption intelligence management system of various instruments or related devices, the related data or signals can be collected and passed to the concentrator, and then pass through the corresponding interface to the primary station. The use of MBUS greatly simplifies the wiring and connection of the energy consumption management system such as residential community, office space, and has a simple structure, low cost, and high reliability.
