Device DDO-24 – 5A АIАR.426449.002
The device DDO-24 is intended for data 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. The device DDO-24 can be used in various automated monitoring and control systems.
Description
Specifications
