Fieldbus Modules

Fieldbus Modules

  • I/O Modules for Modbus®-RTU and SAIA® S-Bus
  • Proven I/O configurations for analog and digital signals as well as PT100/PT1000

Fieldbus modules made by esco - a range of versatile modules well suited for all kinds of control applications. Fieldbus modules from esco are ideal components in order to implement basic PLC functionality in combination with touch panels made by HAKKO.

  • Proven I/O configurations for current and voltage
  • Digital version with input status LEDs and manual output mode (three position toggel switch)

Stores logging data when connected to HAKKO touch panels
