Non-Ex i isolator

Safety and a wide range of functions with non-Ex i isolators
Isolators featuring galvanic separation can be used for decoupling, filtering and signal adaptation. The non-Ex i isolators are a perfect addition to R. STAHL's Ex i isolators. The two-channel versions offer a high channel density over a limited area.

To make your life easier, R. STAHL's ISpac isolators use a pac bus: All you need to do is snap the device onto the DIN rail and pac bus and you're already connected to the auxiliary power supply; error messages are then very easy to read.

Our non-Ex i isolators are also designed to be user-friendly in operation: Two-channel modules for all functions save space, and the three-way reporting of wire breakage and short circuiting speeds up diagnostics. They also boast an impressively long service life of 15 years. And their certification for use in ships' engine rooms bears testimony to their robust construction.

R. STAHL's ISpac isolators are designed with functional safety in mind. These products conform to SIL 2 and SIL 3, including devices with trip amplifier function.

  • Compact: Two-channel modules for all functions
  • Time-saving system for wiring: pac bus
  • Trip amplifier functions for SIL applications up to SIL 2
  • HART-capable
