Description

DC 232/422-485 is a communication converter intended for connecting serial industrial buses and devices with RS 422-485 connector to PC serial port. By connecting this module to PC, capacity of “high-speed” RS422-485 ports is additionally extended. Operation mode (twowired/fourwired) and data rates are easily set with DIP switch. All ports are mutually galvanic isolated. Power supply is from 7V to 32V DC. Mountig is on industrial DIN 35 rail.

Applications

DC 232/422-485 module is suitable for applications in industrial communications and process automation, alarm systems and telemetry. It is used for:

  • Interconnecting distributed I/O modules and PLCs to PC;
  • Galvanic isolation of PC without COM ports to RS 422-485 networks;
  • Field data readout using laptop.
