OUTPUT2 x 4-20 mA + 2 x PNP NC
MATERIALIndustrial hydraulic-service construction
PROTECTIONIP65

Product overview

Application-focused measurement and switching.

The DP3-2A-2PNC monitors both system pressure and filter differential pressure while providing two fixed contamination alarms. Its two-stage logic helps operators act before full filter restriction, and the design is intended to avoid nuisance signaling during hydraulic startup and transient flow changes.

Configuration note

Ratings, materials, interfaces, and approvals can vary by ordered configuration. CASCED US confirms the controlled specification before order acceptance.

Key features

  • Simultaneous system-pressure and differential-pressure measurement
  • Two fixed PNP normally-closed alarm outputs
  • 75% pre-alarm and 100% full alarm for filter contamination
  • Designed to suppress nuisance indications during startup and transients
  • M12 x 1, 8-pin connection for combined analog and switch outputs
