MD-S828ER Intelligent Digital Pressure Switch
Double group relay+RS485 output digital pressure switch
Product details
MD-S828ER IntelligentThe digital pressure switch is designed to control two independent pressure monitoring channels for oil pressure, air pressure, and water pressure. And supplemented with RS485 Modbus protocol output function.
In addition, it has functions such as alarm mode selection, password protection, delayed alarm, and error reset, making the product more accurate and intelligent in achieving pressure alarm and control.
This pressure switch can achieve low-pressure start and high-pressure stop, high-pressure start and low-pressure stop, as well as dual pressure alarm or replace the electric contact pressure gauge. It is a versatile pressure control device. This series of products uses high-speed MCU to collect and process data, with built-in temperature sensors for temperature compensation. It can be widely used in application environments such as automated production line monitoring, pressure vessels, and environmental monitoring.
