Product overview

Application-focused measurement and switching.

The S Series combines electronic switching, local pressure indication, and optional analog transmission in one compact device. Independent switch and reset values, configurable NO/NC behavior, adjustable delay, and password protection simplify machine commissioning while helping prevent unauthorized setting changes.

Configuration note

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

Key features

  • 4-digit red LED pressure display with top-mounted controls
  • Independent switch and reset points with NO/NC selection
  • One or two PNP/NPN switch outputs, model dependent
  • Optional 4-20 mA or 0-10 V analog output
  • Adjustable 0-99.99 second switch delay
  • Password protection and optional minimum/maximum value memory
