DP3 Free Range Type Pulse to Analog Converter
Brand: Yokogawa Electric Corporation
The DP3 is a nest-mounting type DCS-supported pulse-to-Analog converter that receives pulse-train signals and converts them into DC voltage or DC current signals proportional the the frequency.
Features- Internal filter can be set to eliminate chattering (in cases where the input frequency range is up to 100 Hz, the pulse width is 3 Milliseconds or more)
- On-site adjustment for setting the zero/span, low cut point, Input/Output monitoring etc. can be performed from the host system or a handy terminal
