Modules of discrete control and input

io44du

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

FUNCTIONAL CAPABILITIES:

  • 4 groups of contacts (relay) and 4 discreet inputs 
  • Maximum switching current is up to 5 A and voltage is up to 240 V
  • Galvanically decoupled RS485 and USB 2.0 interfaces
  • Can be used as USB to RS485 converter
  • Ability to connect a number of devices to one bus
  • Control via industry standard ModBus protocol
  • Asynchronous registration of input events
  • Relays can be flipped for a defined time interval by one command
  • Access trough the virtual COM-port when connected to the PC by USB
  • Galvanically decoupled inputs can be configured for dry contacts or as voltage inputs
  • Reliable and practical enclosure that can be installed on DIN-rail
  • Setting and test software for module is supplied
