The 8910-PS-DC provides a regulated 12V DC output at 4.9A, specifically designed to power PAC8000 Remote I/O general-purpose nodes. The output voltage is maintained within ±5% tolerance, ensuring stable operation of connected I/O modules. The 8910-PS-DC features a 7ms hold-up time on input supply failure, protecting against brief power interruptions. The 8910-PS-DC's efficiency ranges from 80-82.5% depending on input voltage, minimizing energy loss and heat generation. The 8910-PS-DC includes LED supply health indication for visual status monitoring.

The 8910-PS-DC accepts a wide 18.5-36V DC input range, making it suitable for various industrial power sources, including battery-backed systems and 24V DC supplies with voltage fluctuations. The 8910-PS-DC supports redundant power supply configurations, allowing a second 8910-PS-DC to provide backup power for critical applications requiring maximum uptime. The 8910-PS-DC includes input protection with fuse and supply reversal diode, preventing damage from incorrect polarity connections. The 8910-PS-DC provides power-fail signals to the BIM for both input and output thresholds.

The 8910-PS-DC is approved for Class I, Division 2, Groups A, B, C, D hazardous locations, making it suitable for installations in potentially explosive atmospheres. The 8910-PS-DC operates over a wide temperature range of -40°C to +70°C with derating based on orientation, and can be stored from -40°C to +85°C. The 8910-PS-DC features IP20 ingress protection and is designed to withstand ISA G3 corrosive atmospheres when protected by a suitable field enclosure. The 8910-PS-DC has an MTBF of 80,000 hours at 50°C, ensuring long-term reliability.

The 8910-PS-DC Eaton Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Petrochemical & Refining: Deployed in oil refineries, gas processing stations, and offshore drilling platforms to ensure fail-safe power to hazardous-area automation.
  • Chemical Manufacturing: Powers distributed I/O nodes governing complex process interlocks, reactor temperatures, and emergency venting lines.
  • Energy & Power Generation: Integrated into power plants and gas turbine control systems where system availability is critical.
  • Other Hazardous Industrial Sites: Used in water treatment plants, pharmaceutical cleanrooms, and mining operations susceptible to combustible gases or heavy dust.
  • Carrier Board Connection: Features a pluggable, modular form-factor that seats directly onto dedicated Eaton Node Services Carriers (such as the 8711-CA-NS, 8712-CA-NS, or 8717-CA-PS).
  • Dual Redundancy: The carriers provide two side-by-side power slots. This permits parallel installation of two 8910-PS-DC modules to support bumpless, hot-swappable power redundancy. If one module fails, the secondary module instantly maintains live system execution.
  • Power-Fail Diagnostic Signaling: Features an integrated logic output that issues a discrete "Power-Fail" signal to the Bus Interface Module (BIM) if the output drop threshold dips beneath ≤ 8.5V (± 2V). This immediately informs the network master of an upstream power anomaly.
  • Node Powering for Field Networks: Delivers the internal backplane power required by local node processors. This indirectly ensures seamless network communication across fault-tolerant Ethernet LAN, Peer-to-Peer (P2P) SafetyNet links, or RS485 Modbus serial lines.
  • Hazardous Area Approvals: Certified for installation in Class 1, Division 2, Groups A, B, C, D (T4) hazardous locations. This allows the power cabinet to sit closer to the actual field machinery rather than needing a distant safe-zone control room.
  • High Electrical Isolation: Outfitted with robust galvanic isolation rated for 50 V AC rms / 720 V DC continuous working protection. This stops unexpected voltage surges on the plant's 24V supply line from destroying delicate processor equipment.
  • Environmental Resilience: Complies with the ISA G3 harsh environment standard via conformal-coated internal circuitry. It functions perfectly across a wide temperature spectrum from -40°C to +70°C using natural convection cooling.
  • Electrical Safeguards: Built-in protections include a supply reversal diode (guarding against incorrect terminal wiring), thermal shutdown, and automated electronic current limiting to protect against output short-circuits.
