VJQ0 Single, Dual Output Analog to Pulse Converter
Brand: Yokogawa Electric CorporationThe VJQ0 is a compact, plug-in Analog to pulse converter that receives DC voltage or DC current signal and converts it into isolated pulse-train signal.
The converter provides either open-collector output or contactless AC switch output.
Features- A Wide Choice of Input Signal Ranges
- A Low-Level Cutoff Function (Which is Set at 1% as Standard, But Can be Set between 1% and 10%)
- 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
- lose Side-by-Side Mounting
