This module adopts ASCII communication protocol, compatible with mainstream module communication protocol. It is reliable and stable, and has fast response speed. It can be changed to Modbus RTU communication protocol. Choose one of ASCII and Modbus RTU, and change it according to customer needs!
This module is a 4-channel optically isolated I/O input/5-channel power single-pole relay output module. The relay output can carry a load of about 300W and uses RS485 communication.
Remarks: RS485 communication can reach 1.2 kilometers. This module can be equipped with multiple modules when using 485 communication, because each module can be set with a different address.
The occasions when this module is available:
1. Collect and report the on-off value of the parking lot ground coil to the computer;
2. The switch value of various alarm systems is collected and reported to the computer;
3. Count the switch value and report it to the computer;
4. The product count of the automatic production line is reported to the computer;
5. A variety of applications where the switch value is required to be reported to the computer for control occasions;
Special attention: If you want to use the 5-way relay output of this module, it is not easy to use in the flammable gas and explosive occasions, hehe, because we know that the closing of the relay is very easy to produce sparks! ! ! ! ! !
