TTL to MBUS, serial port to MBUS slave module, no spontaneous collection!
Brief introduction:
The TTL MBUS module, optical TTL signal and MBUS signal isolation, mutual interference, MBUS receiving circuit from the bus to take power, does not require a separate power supply, but due to optical TTL signal and MBUS signal isolation, so the need to separate power supply! The module adopts FC722 slave MBUS chip, which is stable and anti-interference. Ultra small, easy to install with any device!
Main parameter:
1, communication baud rate: 300-9600bps
2, TTL signal: compatible with 3.3V, 5V or other
3, bus voltage12V-42V can be adjusted
4,Bus current200uA— 3mA continuous
5, VIN:TTL signal voltage value (if TTL is 3.3V, VIN input 3.3V voltage, TTL is 5V, VIN input 5V voltage)
6, data interface: TXD connected to external TXD; RXD access to external RXD
7There is no spontaneous self access (TSS721, internal Uart is a closed loop, so there is spontaneous phenomenon, and this module does not)
Dimensional drawing:
Application field:
1 simulated intelligent water meter, gas meter, heat meter, meter reading application
2 simulating the application of automatic meter reading in Smart Grid
3 analog intelligent home control network applications
4 simulate fire alarm and linkage network application
5 simulation central air conditioning control system application
6 analog intelligent sensor network applications
Declaration:
The module of all components in the customer needs to be exposed, debugging ability and professional knowledge, it can not touch other power etc.!
Module sold for one week, confirmed that the use of error, the use of a month later, no longer bear the replacement, maintenance and other responsibilities,Buyers confirm purchase!
Note: large quantity, price can be discussed!!!!!
