Modules of discrete control and input

Video Internet Technologies Company has developed the modules of discrete control and input AVMOD, IO44D, IO44DU.

The modules are designed for discrete control with different load and inquiries for status of discrete inputs through the interface RS485 or USB.

 

FUNCTIONAL CAPABILITIES:

  • 4 groups of contacts and 4 discreete inputs 
  • Maximum current up to 5A and voltage up to 240V
  • Galvanically decoupled RS485 and USB 2.0 interfaces
  • Can be used as USB to RS485 converter
  • Can be stacked with other RS485 devices on one bus
  • An industry standard ModBus protocol
  • Asynchronous input events registration
  • Relays can be flipped for a defined time interval by one command
  • Access trough the virtual COM port when connected to USB
  • Galvanically decoupled inputs can be configured for dry contacts or as voltage inputs
  • Inputs states can be translated to relays
  • Reliable and practical enclosure for DIN-rail
  • Test and configuration utility for PC is supplied
