DP1 Pulse Repeater

Brand: Yokogawa Electric Corporation

The DP1 is a nest-mounting type DCS-supported pulse repeater that receives pulses from voltage-free contacts, open collector contacts, voltage, and current, and converts them into isolated transistor-contact pulses.
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)
