Modbus-Rtu 1 utas 5V relé modul kapcsoló bemenet és kimenet RS485/TTL soros kommunikáció
Modbus-Rtu 1 way 5V relay module switch input and output RS485/TTL serial communication
Product Introduction
One Modbus RTU relay module is equipped with a mature and stable 8-bit MCU and RS485 level communication chip. Using standard Modbus RTU format RS485 communication protocol, it can realize 1 optical coupler input signal detection and 1 relay signal output, which can be used for digital quantity detection or power control occasions.
