Products Description
The Honeywell F860-CA Fieldbus Power Supply Component is a robust power distribution module designed to deliver stable and controlled DC power to fieldbus segments in industrial communication systems.This unit operates within a DC input range of 19.2 V to 30.0 V, supporting flexible integration into standard industrial power systems. Depending on the configuration, it draws approximately 3.5 A when paired with F801 modules and up to 6.0 A with F802 modules, ensuring sufficient power delivery for multi-segment fieldbus networks.The module provides regulated output voltages tailored to system configuration, delivering 21.5–24.0 V for F801 setups and 28.0–30.0 V for F802 configurations, ensuring stable voltage supply across connected field devices. Each segment is designed with a controlled current output of 350 mA (F801) or 500 mA (F802), with built-in current limiting above 370 mA and 520 mA respectively, enhancing protection against overload conditions.Overall, the Honeywell F860-CA Fieldbus Power Supply Components provide a dependable power foundation for fieldbus communication networks, combining stable power delivery with industrial-grade signal conditioning and network support functions.

Performance Excellence & Benefits
- Simultaneous Carrier-Wave Impedance Matching: The F860-CA is engineered with a specialized passive conditioning circuit that allows DC power and high-frequency digital communication packets to coexist seamlessly on a single twisted pair, preserving strict network impedance without signal attenuation.
- Honeywell Experion PKS Backplane Alignment: Architected specifically for flawless integration into Honeywell distributed control system (DCS) architectures, the F860-CA maps natively into standard marshalling racks, providing predictable power infrastructure for robust fieldbus interface modules.
- Galvanic Trunk-to-Segment Isolation: The F860-CA incorporates high-density galvanic isolation barriers between the main system power supply and the individual network segments, containing localized field short-circuits and protecting central processing nodes from catastrophic voltage migration.
- Advanced Dielectric Noise Rejection: Operating within extreme, non-linear electromagnetic fields, the module features active common-mode rejection filters that prevent high-voltage switching spikes and heavy machinery interference from corrupting critical digital fieldbus frames.
- Multi-Drop Field Device Ingestion: Designed to sustain complex distributed instrumentation topologies, the F860-CA delivers continuous, low-ripple current capacity necessary to drive dozens of intelligent, multi-variable smart transmitters and valve positioners across an expanded physical radius.
