Working Principle: With the rapid development of industrial Internet of Things technology, the existence of data acquisition terminal mode of IOT instrument has become a reality, it supports RS485 output or two-wire system (4-20) mA transmission, supporting 1-4 channels of data acquisition, and internal storage of the vast majority of engineering units. It has many functions such as digital output, PID output, proportional pulse and frequency output
Application: For complex industrial processes, sewage treatment, water reuse, environmental monitoring, industrial field control, chemical process, thermal detection and discrete control, data transmission control and remote data transmission
Characteristics:
• 1 Board - card module design, easy to select onboard acquisition parameters.
• 2. 1-4 channels of arbitrary attribute data acquisition
• 3. 4 input parameters can be arbitrarily selected RS485/4-20mA;
• 4 Internal integrated WiFi, download the APP and view the data on the phone and set the function
• 5 RS485 to Lara and RS485 to ZigBee modules are used to construct Wireless data transmission of the Internet of Things
• 6. Uplink industrial RS485 interface can connect DTU to cloud data collection, view, monitoring and saving:
• 7 Internal storage of multiple units of engineering volume:
• 8. Two-way 4-20mA two-wire input;
• 9. One of the quantities can be converted to standard 4-20mA output .
• 10 The 3-way relay can be configured with any channel overrun alarm or Dl associated output
• 11 1 channel high speed photoelectric switch port, programmable logic pulse/frequency operation mode.
