Pepperl+Fuchs PS2500/PM-115 Power Supply Module – PS2500 Zener Barrier System
Imagine a critical process plant running 24/7 — temperature sensors feeding a DCS, pressure transmitters guarding a reactor, and level switches protecting a storage tank. Now imagine the power supply feeding the entire Zener barrier rail fails silently. Within seconds, every intrinsically safe field loop loses its reference voltage. Alarms go dark. Operators lose visibility. The cost of an unplanned shutdown in a refinery or chemical plant can exceed tens of thousands of dollars per hour. The Pepperl+Fuchs PS2500/PM-115 exists precisely to prevent this scenario — delivering stable, conditioned 24 VDC power to the PS2500 Zener barrier system so that your intrinsically safe field instruments never lose their lifeline.
Within the PS2500 modular barrier system, the PM-115 power supply module occupies the master position on the DIN-rail carrier, providing centralized power distribution to all downstream Zener barriers and associated signal conditioners. Pepperl+Fuchs, headquartered in Mannheim, Germany, is the originator of the Zener barrier concept and remains the global benchmark for intrinsic safety components. The PS2500/PM-115 is engineered to IEC 60079 intrinsic safety standards and is widely deployed across oil & gas, petrochemical, pharmaceutical, and water treatment facilities worldwide.

Frequently Asked Questions
Q: Is the PS2500/PM-115 compatible with all PS2500 series Zener barriers?
A: Yes. The PM-115 power supply module is designed as the master power unit for the PS2500 DIN-rail carrier system and provides power to all PS2500 series Zener barriers mounted on the same carrier. Always verify your specific carrier model with Pepperl+Fuchs documentation.
Q: What is the output voltage of the PS2500/PM-115?
A: The PS2500/PM-115 provides 24 VDC regulated output to the PS2500 system rail. For precise electrical specifications including current capacity and ripple, refer to the official Pepperl+Fuchs datasheet or contact our technical team.
Q: Can this power supply be used in ATEX Zone 1 hazardous areas?
A: The PM-115 is a safe-area mounted power supply module that provides power to intrinsically safe Zener barriers. The barriers themselves limit energy to the hazardous area field instruments. The PM-115 must be installed in a safe area (non-hazardous) enclosure.
Q: Do you provide a warranty or return policy?
A: Yes. All products are covered by our quality guarantee. If a unit is found to be defective or not as described upon receipt, we offer replacement or full refund. Contact support@konmask.com within 7 days of receipt.
Q: How long does international shipping take?
A: Express courier (DHL/FedEx) typically delivers within 3–7 business days to most destinations. Sea freight options are available for bulk orders. Exact lead times are confirmed at the time of quotation.
Q: Can you provide the original Pepperl+Fuchs datasheet?
A: Yes. We can provide the official manufacturer datasheet and available certification documents upon request. Email us at support@konmask.com.
