VM20.4DI Module 4 digital inputs

Module 4 Digital Inputs


The VM20.4DI is designed to extend the ability to receive digital signals scattered throughout the building to simplify installation and reduce cabling. The VM20.4DI can be configured via Modbus or VDC application for more functionality and simplified commissioning, this configuration interface is designed to easily configure the equipment, define variables, limits, functions, addressing among other possibilities which allows universal adaptation.

This equipment was built with a high degree of robustness, flexibility and adaptability to each situation, having a two-year guarantee against manufacturing defects.

Modbus communication gives the device a strong versatility and can be interconnected to any GTC system.

  • Each VM20.4DI is ready to receive up to 4 digital signals
  • Cabling reduction compared to the traditional method
  • Extractable connection terminals, facilitating electrification
  • Communication via RS-485 - Modbus
  • Easy to address and commission
