LORA Wireless Module Remote Control Transparent Transmission MODUBUS RTU Protocol Digital Input Relay Output


Need a pair of Lora wireless modules to use
1 Introduction
LORA-MODBUS-1DI1DR is a module that integrates 1-channel digital acquisition, 1-channel digital control, MODBUS RTU, MODBUS RTU to LORA communication, and wireless remote control functions.

Support MODBUS RTU master station to directly access this module through 485 serial port, or use MODBUS RTU to LORA communication function, that is, with our company’s “LORA wireless serial port transparent transmission module” to access this module through LORA communication, and connect the module’s 485 serial port to the module Other slave stations (need to enable wireless forwarding mode), that is, add the function of LORA wireless transmission communication to the MODBUS module sold by our company
In addition, with another LORA-MODBUS-1DI1DR module to enable the wireless remote control function, the state of one switch input of one 1DI1DR can be fed back to one switch output corresponding to another LORA-MODBUS 1DI1DR through LORA wireless transmission. .

In short, the module – to a certain extent, reduces the 485 wiring between the MODBUS RTU master station and the slave station module, or the wiring from the switch to the access device, thereby reducing the amount of construction and maintenance, and improving the flexibility of installation. Economical and stable, easy to install, and highly adaptable products.
