  • A wide choice of input and output signal ranges
  • Four isolated ports (input, output-1, output-2, power supply and grounding) on a dual-output model
  • A withstanding voltage of 2,000 Vac
  • A wide supply voltage range - supporting both 100 V and 200 V power lines of AC or DC
  • Close side by side mounting
