Description
Product Description:
9988 super controller provides single-channel input, it can receive RS485 signal, current signal, frequency signal, through the acquisition of the above signals, it can complete the display control of flow, PH/ORP, conductivity, pressure, temperature, liquid level, salinity, dissolved oxygen, batch processing and other output 4-20mA signal sensors.
It features a large (75x47mm) backlit display, with a bar graph at the top that allows you to observe the dynamics of the gauges clearly.
Features:
1: Accurate measurement of various parameters of fluids.
2: The output supports RS485 MODBUS RTU communication protocol.
3: The output supports one way output of 4-20mA signal.
4: The output supports two dry contact relays, which can achieve fast and accurate response
5: The input supports one way mA singal and one way RS485 MODBUS RTU singal, which can be compatible with sensors with mA current output or RS485 MODBUS RTU communication protocol;
6: Power input with anti-reverse protection
Applications:
1: Wastewater treatment
2: Pure water preparation system
3: Chemical Measurement
4: Cooling tower
5: Reverse osmosis system
6: Aquarium life support system
7: Central dosing system
