GENERAL FEATURES

TECHNICAL SPECIFICATIONS

Communication

MI002875-E

Power supply and serial connection wiring facilitated by means of a bus that can be 

used in the DIN guide.

Functioning modality is configurable by DIP-switch.

RS485 serial communication with protocol MODBUS-RTU

High immunity to the RF disturbs

Transparent to the ModBUS protocol

Isolation between communication and power supply: 1500 Vac.

It is possible to implement MESH networks

BRIDGE or REMOTE I/O functioning

The  Z-LINK1  modules  represent  a  communication  systems  for  data  acquisition  and 
transmission  in  the  process  control  and  industrial  /  civil  automation.  Based  on  an  UHF 
modem  radio,  Z-LINK1  is  able  to  comunicate  with  Z-PC  line  modules  through  ModBUS 
protocol. Z-LINK1 represents a new platform communication in radio frequency.
