Product Introduction

Includes 6 RS232 serial ports, 1 RS485 serial port, 8 channels of 4-20mA analog signal input ports, and 4 channels of switch input ports. Among them, there are 6 digital communication ports RS232 used to communicate with intelligent instruments and meters with similar interfaces, read instrument data, such as COD online monitoring instrument, ammonia nitrogen online monitoring instrument, total phosphorus online monitoring instrument, heavy metal ion online monitoring instrument, flow meter, etc. If some instruments have RS485 interfaces, data can be directly read using the RS485 serial port of HH-6300. 8-way 4-20mA input port, used to connect standard 4-20mA transmitter current signals, such as some models of pH meters, flow meters, pressure transmitters, etc. It can also be connected to current transformers to measure the operating current of environmental protection facilities and monitor the operating power of environmental protection facilities. And the 4-channel switch input can be used to monitor the on/off status of environmental protection facilities.
