VJHF Super Speed Response Isolator
Brand: Yokogawa Electric CorporationThe VJHF is a compact, plug-in, super speed isolator that converts DC voltage or DC current signals into isolated DC voltage or DC current signals.
Features- Ultra-fast 50 microseconds signal conversion for a 63% response
- 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
