Webcode overview

Ex i isolators

Intrinsically safe isolators offer a wide choice and are designed to make your life easier
Point-to-point connections with ISpac isolating barriers are a proven solution that is easy to implement. ISpac isolating barriers are particularly easy and inexpensive to install. Only R. STAHL allows you to install all devices individually, in groups or in a pac-Carrier.

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

Our isolating barriers with intrinsically safe interface are also designed to be user-friendly in operation: Dual-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 isolating barriers are designed with functional safety in mind. These products conform to SIL 2 and SIL 3, including devices with trip amplifier function.

Compact: Dual-channel modules for all functions
Time-saving system for wiring: pac bus or pac carrier
Broad range of applications: Can be used for SIL applications up to SIL 3
HART-capable
