The ABB P-HB-RFO-80010000 serves as the primary RFO-800 Repeater Module utilized to execute fiber optic signal amplification and segment isolation across Net 90 and S800 Harmony platforms.

Model Architecture & Hardware Identifier

• P-HB-RFO-80010000: Complete assembly order part number for factory-certified module procurement.

• RFO-800: Hardware spare model designation for field unit swap and maintenance records.

• Hnet Repeater: Fiber optic physical layer repeater interface optimized for S800 Harmony architectures.

Physical Parameters & Operating Constraints

Deterministic Network Bus Velocity & Scalability

Designed for deterministic node communication, the module regulates Hnet data propagation at a fixed transmission rate of 2 Mbit/s. Internal processing circuitry optimizes backplane bus communication velocity across distributed topology nodes without introducing jitter. The architecture supports expanded I/O density scaling across fiber optic networks while preserving firmware flash compatibility during controller-level software updates.

Field Wiring & Fiber Optic Assembly Rules

• Mount the unit securely on the corresponding sub-rack backplane position until mechanical locking tabs engage.

• Route incoming 24 VDC power through clean, fused distribution blocks within the +/-20 % operational tolerance.

• Inspect fiber optic cable connectors for surface cleanliness prior to insertion into optical transmitter/receiver ports.

• Maintain minimum physical bend radii on all optical patch cables to prevent signal attenuation and glass core cracking.

Technical Hardware Reference FAQ

• What is the nominal operating data rate for the RFO-800 repeater module?

  The module processes Hnet network communication at a fixed, deterministic transmission velocity of 2 Mbit/s.

• What supply voltage range is required to power the module?

  The module operates on an auxiliary 24 VDC input and tolerates a input fluctuation range of +/-20 %.

• What is the typical current draw during continuous execution?

  Under standard operating conditions, the unit draws a nominal current of approximately 100 mA at 24 VDC.

• What ambient temperature limits apply during field operation?

  The hardware is rated for continuous field operation across ambient temperatures from 0 to +60 deg C.

• What is the spare part reference code for this repeater assembly?

  The manufacturer spare model identifier for direct hardware replacement is designated as RFO-800.

• How should fiber optic cables be maintained during installation?

  Connectors must be cleaned with lint-free optical wipes, and cables must not exceed minimum bend radius limits.

• Does the repeater require manual DIP switch or baud rate selection?

  No, the unit handles physical layer signal amplification transparently without hardware DIP switch selection.

• What environmental storage limits must be observed prior to commissioning?

  The equipment must be stored within a dry environment between -40 and +85 deg C, with non-condensing humidity.
