Device DDIО-24 AИAР.426449.004-01
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.
- 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:
- when the circuits are closed - 250 V, 5 A, 1000 VA / W;
- when AC circuits are opened - 250 V, 5 A, 1000 VA / W;
- when opening DC circuits up to 30 V - 5 A;
- when opening DC circuits up to 125 V - at least 50 W;
