Ttl to Mbus, Serial Port to Mbus Slave Module, Instead Of Tss721a, Signal Isolation

Brief introduction:TTL to MBUS module, TTL signal and MBUS signal optocoupler isolation, no interference, MBUS receiving circuit from the bus power, do not need to power alone, because the TTL signal and MBUS signal optocoupler isolation, so optocoupler needs to power alone! The module adopts FC722 slave MBUS chip, which is stable and strong anti-interference. The ultra small volume is easy to install with any equipment!Color: greenMaterial: PC+MetalMain parameters:1. Communication rate: 300-9600bps2, TTL signal: compatible with 3.3V, 5V, or other3. The bus voltage 12V-42V can be adapted4. Bus current 200uA - 3mA continuous5, 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 connects to external TXD; RXD connects to external RXD.7, there is no spontaneous self (TSS721 internal Uart is a closed loop, so there is spontaneous spontaneous phenomenon, and this module does not).Application areas:1, application of analog intelligent water meter air meter caloric meter reading2. Application of analog smart grid automatic meter reading3. The application of analog intelligent home control network4. Simulation of fire alarm and the application of linkage network5, simulation of the application of central air conditioning control system6. Application of analog intelligent sensor networkPackage Contents:1 x serial port to MBUS slave moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +\/- 1-3cm.
