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.
