Modbus Protocol RTU, 8 AI, 2 AO, 8 DI, 4 DO, 3 PI, 3 HART, 1 RS232, 1 RS232/RS485, 1 Ethernet



The Super32-L is a series of compact RTU that brings advanced automation capabilities and open programming to applications requiring small I/O points. It is built on a high performance 32-bit processor with embedded real-time operating system to meet all monitoring and control requirements. A broad array of communication ports and extensive protocol library provide broad network compatibility. Super32-L also offers an open programming environment that supports all IEC61131-3 languages. A rich library provides numerous pre-engineered function blocks, which project engineers find invaluable.



  •  High performance 32-bit CPU with embedded real-time operating system (RTOS)
  • Compact design with up to 25 I/O points and 4 communication ports
  • Extensive communication protocols such as Modbus RTU/ASCII/TCP, DNP3
  • Open programming environment that supports all IEC61131-3 languages including LD, FBD, IL, ST and SFC
  • Built-in watchdog timer helps to protect your application from erroneous outputs
  • All the terminal blocks are isolated from the main control circuit.
  • Low power consumption design, ideally for solar-powered installations
  • Wide operating temperature range, well suited for harsh environment applications: -40°c~+70°c
  • Industry-standard design, using DIN rail for mounting, easy to install on-site



Super32-L RTU is specifically designed for the applications under environments with extreme temperatures and humidity. Some examples of application fields are:

     Oil and gas well heads monitoring and control

     Oil and gas pipeline supervision, metering and control

     Natural gas and heating distribution

     Water and wastewater treatment plants

     Street lights monitoring and control

     Other systems or device where temperature, pressure, flow etc. need to be supervised and controlled
