Device DDIО-24 AИAР.426449.004-01

Device DDIО-24  AИAР.426449.004-01 10319

Device DDIO-24 can be used in various automated monitoring and control systems. Device DDIO-24 is intended for input of discrete electrical signals for their processing and data exchange via three-wire serial RS485 interface lines with Modbus RTU protocol and exchange via three-wire serial RS485 interface lines with the Modbus RTU exchange protocol and for issuing commands received via the interface by closing "dry" contacts of the relay.

Specifications:

  • Number of digital input channels - 12 channels with galvanic isolation.
  • The dielectric strength of the isolation of the discrete input channels and power inputs is 1.5 kV.
  • Type of voltage on the discrete input channel - DC or AC.
  • The maximum allowable voltage on the digital input channel is 250 V.
  • The “logic zero” level is from 0 to 11V, the “logic one” level is from 17 V to 24 V.
  • Number of discrete output channels - 12 channels with galvanic isolation, "dry" relay contacts.
  • The dielectric strength of the discrete output channels and power inputs is 1.5 kV.
  • The switching capacity of the relay contacts is as follows:
