ABB 3BDH000013R1 SA 811F

ABB 3BDH000013R1 (SA 811F) is an ABB Freelance / AC 800F system power supply module designed to provide stable DC power for ABB process control systems. It is mainly used with PM 802F and PM 803F controller units in the ABB Freelance DCS environment.

Product Overview

• Manufacturer: ABB
• Model: SA 811F
• Order Number: 3BDH000013R1
• Product Type: Power Supply Module
• System Family: ABB Freelance / AC 800F DCS
• Input Voltage: 115 / 230 VAC (auto-ranging)
• Output Power:
  • 5 VDC / 5.5 A
  • 3.3 VDC / 6.5 A
• Application: Controller and communication module power supply

Technical Description

The ABB SA 811F converts the incoming AC supply voltage into regulated DC voltages required by AC 800F controller components. The module provides electrically isolated output voltage with high stability and low residual ripple.

Key features include:

• Wide input voltage range: 115–230 VAC
• Stable regulated DC output
• Electrical isolation between input and output
• Protection against:
  • Open circuit
  • Overload
  • Continuous short circuit
• Power-fail monitoring function for controlled system shutdown

When a power interruption longer than approximately 5 ms occurs, SA 811F generates a power-fail signal. The controller uses this signal to safely shut down operations and ensure a controlled restart after power restoration.

Application Range

ABB SA 811F is commonly applied in:

• ABB Freelance DCS control systems
• ABB AC 800F automation platforms
• Industrial process control applications
• Power generation plants
• Chemical and petrochemical industries
• Water treatment facilities
• Manufacturing automation systems

It is typically installed as part of an AC 800F controller station to supply power for CPU, communication, and I/O modules.

Compatible Components

• ABB PM 802F Controller
• ABB PM 803F Controller
• ABB AC 800F automation modules
• ABB Freelance engineering systems

Conclusion

The ABB 3BDH000013R1 SA 811F Power Supply Module is a reliable industrial power supply component for ABB Freelance DCS and AC 800F control systems. With robust protection features, stable DC output, and dedicated power-fail handling, it ensures safe and continuous operation of critical automation controllers.
