Stahl Electromach - SPAC Barriers

The improved ISpac isolator barriers from R. STAHL provide intrinsically safe interfaces for field equipment. They are particularly suitable for functional safety in SIL 2 and SIL 3 applications and can be easily installed on DIN rails or a pac carrier/backplane. R. STAHL’s solutions offer numerous advantages during installation and throughout the production process lifecycle:  

• Smart design, resulting in 30% space savings in the cabinet.  
• Enhanced energy efficiency.  
• Front-facing labeling and light indication.  
• Removable terminals (screw/push).  
• Redundant power supplies to improve availability.  
• Combined error signaling for installed barriers.  
• Available for all standard signals (Analog, Digital, Temperature).  
• Flexible solutions, including adapters for quick and easy replacement of existing 19” cards (E-Cards).  
• Robust, vibration-resistant design.  
• Flexible adjustments can be made effortlessly.  
• Suitable for harsh industrial environments.  
• Simple and safe operation.  
• Optional decoupling of HART signals.  
• Global certifications.  

ISPAC pac-Bus

The Series 9294/31-12 pac-Bus supplies power to 30 to 50 Series 92xx ISpac devices. Auxiliary power can be supplied to the pac-Bus segment via the 9194/50-01 terminal set. Alternatively, the 9193/21-11-11 power module can be used to provide redundant power and to read collective error signaling. The pac-Bus can be mounted onto NS 35/15 and NS 35/7.5 DIN rails. The 9294/31-12 pac-Bus can also be combined with the 9194/31-17 pac-Bus.  

• Reduced costs due to faster wiring of ISpac devices.  
• Mounted and snapped onto standard DIN rails – extendable at any time.  
• Suitable for industrial environments subject to vibrations.
