Digital remote control adapter

LAN / USB / RS-232C / RS-485 / GPIB Control

To remotely control this high-voltage power supply via LAN or USB, purchase both an digital converter (CO-HV) and optical isolation adapter. The digital converter (CO-HV) converts the analog control signal of the high-voltage power supply into a digital optical signal. The optical isolation adapter converts interface signals such as LAN and USB to optical signals.

For details, check the CO / USB series for a digital converter (CO-HV) and optical isolation adapter.

  • Optical isolation
  • 16-bit (1/65535) high-resolution A / D .
  • Computer and PLC controlled.
  • Protecting from discharge and surge.
  • Ideal for automation and labor-saving systems.
