VJD1 Isolated Single & Dual Output Tachometer
Brand: Yokogawa Electric CorporationThe VJD1 is a compact, plug-in tachometer converter that receives single-phase, AC voltage signal from an electric tachometer and converts it into isolated DC voltage or DC current signals.
Features- AC-to-DC Conversion Based on Mean-Value Rectification
- 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
