Brief introduction:
Statement: our products are independently developed, tested and put into operation without any agents. Any similar products are counterfeit or second-hand.
Industrial RS485 to MBUS host module, internal RS485 and MBUS circuit are completely isolated from each other. The RS485 interface adopts the national grid standard, which requires 220 voltage and 2 hours without damage. The anti-static ability of all interfaces is + 8KV. MBUS bus overload and short circuit automatic protection, protection enters ultra low standby power consumption, after overload and short circuit revoke, automatic recovery.
Module characteristics
1. fully conforms to MBUS international standards and national standards
2. wide voltage non polar input to avoid voltage connection
3. provideWithin the standard rangeBus high level, customizable
5. small size, easy to carry on site debugging
6. no spontaneous self absorption and error in data transmission range.
7. communication baud rate 300~9600 can be adapted
8. according to the load, the device can bring about 20 standard MBUS from the device
9. internal RS485 and MBUS are completely isolated from each other
TenThe shell has no word or pattern logo, and customers can print logo on their own.
11. short circuit protection low power function. After the bus is short circuited, the State indicator lights go out, and the internal automatic shutdown bus enters the protection state. Approximately 4S checks whether the bus is short circuited, and the short circuit cancellation is automatically recovered in 4S.
Note:The MBUS standard high level is a range, not a fixed value, such as 36V, and the actual high level is normal in 20~42V.
Parameters:
Input voltage: minimum 9V; typical value 12V; maximum 15V(Absolute maximum voltage is not more than 18V)
Static power consumption: 12V input 15 + 1mA
Carrying capacity: 12V input 20 standards from the device, the input voltage is reduced, the load drop is increased instead.
Internal isolation pressure:
2000VAC
Working environment temperature: -25 to 75 degrees centigrade
Storage temperature: -30 to 80 degrees centigrade
Interface
Antistatic ability: + 8KV
Buyers note:
1.MBUS host module can only communicate with the slave module. The main module can not communicate with the main module, and the slave module can not communicate with the slave module. Only one host can exist on the same MBUS bus, not two or more than two hosts.
2. module can carry up to 20 standards at most, from the opportunity to make the module enter the protection state.
3. bus protection function, MBUS bus will not damage after short-circuit, but try to avoid long short circuit.
4. all interfaces of this module can not touch strong power
