RS485 communication module mainly include 3 series rs485 input output relay module,rs485 digital input module, rs485 analog input output module respectively. The protocal is standard modbus rtu/tcp .The interface support rs485,rs232 or lan.
Description:
Relay module with rs485 is also called remote control.The relay output is actually a switch contact.It can connect to AC DC load. This board include rs485 input output module, rs485 relay output module, rs485 expansion board with lan. RS232 serial port is also supported of some module.
rs485 digital input module is also called digital acquisition module which usually connect tovarious buttons, switches, keysetc.This module use to acquire the digital data.
rs485 analog input output module always control the analog quanties . Analog input acquire the data fromsensors,pressure transmitters,voltage transmitterand the analog output module controlanalog equipment. They all supoort modbus rtu.
