ABB UFC762AE101
Product Introduction
The ABB UFC762AE101 is a high-availability PROFIBUS DP communication module designed for ABB’s S800 I/O platform. As a critical component in distributed control architectures, this module enables deterministic data exchange between ABB controllers (e.g., AC 800M) and field devices across process industries. The ABB UFC762AE101 supports master/slave redundancy with <1ms switchover, ensuring uninterrupted operation in safety-critical applications.
Engineered for seamless integration with ABB’s 800xA DCS and Symphony Plus control systems, this module extends PROFIBUS DP-V1 functionality to intelligent field instruments, motor starters, and remote I/O drops. Its dual-port architecture allows daisy-chain or redundant ring topologies, while diagnostic LEDs provide real-time network health visibility. For asset-intensive facilities, the ABB UFC762AE101 delivers robust connectivity with compliance for hazardous area deployments.
Core Advantages and Technical Highlights
Deterministic performance: Achieves 12 Mbps data rates with jitter <1µs, enabling precise synchronization of drives and process instruments. Hardware-based PROFIBUS ASIC handles protocol processing independently, freeing controller resources.
Fault-tolerant architecture: Dual-redundant modules operate in “hot standby” mode. Automatic switchover during fiber break or power loss maintains continuous process control. Module replacement without system shutdown.
Advanced diagnostics: Built-in oscilloscope functionality detects signal reflections, cable breaks, or EMI interference. Stores 1,000 event logs with timestamped bus errors for root cause analysis.
Hazardous area compliance: ATEX/IECEx Zone 2 certification allows installation in explosive atmospheres without additional barriers. Galvanic isolation (500V) between fieldbus and backplane.
Cybersecurity hardened: Supports PROFIBUS Security with encrypted FDL telegrams. MAC address filtering blocks unauthorized devices.
Typical Application Scenarios
In pharmaceutical batch plants, the ABB UFC762AE101 networks hygienic flowmeters and CIP skid valves via PROFIBUS PA segment couplers. Its SIL 2 certification validates use in safety instrumented systems (SIS) for reactor pressure protection.
Power generation facilities deploy redundant UFC762AE101 pairs to connect turbine governor systems with remote marshalling cabinets. The module’s -40°C cold-start capability ensures reliability in outdoor switchyards, while 12 Mbps speed synchronizes excitation control across multiple generators.
For offshore drilling platforms, the ATEX-certified module networks blowout preventer (BOP) control pods, with redundant fiber-optic rings surviving cable shearing incidents. Real-time diagnostics monitor connector corrosion in high-salinity environments.

Installation, Commissioning and Maintenance Instructions
Installation preparation: Mount redundant UFC762AE101 modules in separate S800 baseplates. Use ABB-recommended PROFIBUS cables (e.g., Belden 3079F) with 90Ω impedance. Ground shield at both ends via D-sub connector screws. Maintain bend radius >75mm.
Maintenance suggestions: Monitor “Telegram Error Rate” in Control Builder M software monthly; rates >0.1% require cable inspection. Clean D-sub contacts annually with isopropyl alcohol. Replace backup batteries every 3 years. During firmware updates, disable redundancy temporarily.
Service and Guarantee Commitment
ABB provides a 36-month warranty for UFC762AE101, covering 24/7 technical support with on-site response within 24 hours for critical process interruptions. Extended lifecycle support guarantees spare parts for 15 years post-discontinuation. All modules undergo 96-hour HALT testing (85°C @ 100% humidity) and 1,000+ insertion cycles on connectors. Cybersecurity firmware patches are delivered via ABB Ability™ portal. PROFIBUS conformance certification includes PNO test reports.
