Description

Product Overview

The ABB AO801 is a high-performance analog output module engineered for industrial automation systems, specifically designed for ABB’s S800 I/O platform. As part of the S800L I/O series, this module provides eight isolated analog output channels, supporting 0–20 mA or 4–20 mA signals with 12-bit resolution and ±0.1% full-scale accuracy . Its compact design (86.1 mm × 58.5 mm × 110 mm) and lightweight construction (0.24 kg) make it ideal for space-constrained control cabinets, while the rugged IP20-rated enclosure ensures reliable operation in harsh industrial environments .

Integrated into the Advant 800xA distributed control system (DCS), the AO801 enables seamless communication via Profibus DP, Modbus RTU, or Advant Fieldbus 100 (AF 100) protocols, allowing real-time data exchange with PLCs, HMIs, and other I/O modules . Each channel features short-circuit protection and self-diagnostic capabilities, ensuring proactive fault detection and minimizing downtime. The module’s hot-swap functionality further enhances maintainability, enabling replacement without system shutdown.

Installation and Maintenance

Installation Preparation:
Ensure the S800 I/O rack is properly grounded and powered off. Mount the ABB AO801 in an available slot, securing it with retaining clips. Connect the 24 V DC power supply to the terminal block, verifying correct polarity. For communication, link the module to the CPU via Profibus DP, Modbus RTU, or Advant Fieldbus 100. Wire field devices to the output terminals, following the signal type specified in the configuration. Use 0.05–2.5 mm² solid or stranded wires with a recommended torque of 0.5–0.6 N·m .

Maintenance Recommendations:

Routine Checks: Inspect LED indicators monthly to verify normal operation (green for power, yellow for faults). Clean dust from the module’s vents to prevent overheating.
Calibration: Perform annual calibration using a certified signal source to maintain output accuracy. Use ABB’s diagnostic tools to verify channel performance.
Firmware Updates: Periodically update the module’s firmware via the CPU to incorporate new features and security patches, ensuring compatibility with evolving system requirements.
Spare Parts Management: Keep a spare AO801 on hand for rapid replacement in case of component failure, minimizing production downtime .
