ABB DO802 3BSE022364R1 S800 Series Relay Output Module Best Price Quote

ABB DO802 Module Overview

The DO802 (Article Number: 3BSE022364R1) functions as an 8-channel relay output module engineered specifically for the ABB S800 I/O architecture. Built with individually isolated normally open (NO) contacts, the DO802 handles heavy-duty switching up to 250V a.c. or 110V d.c. at 2A. Each channel incorporates optical barriers and EMC shielding, making the DO802 series ideal for robust industrial automation environments demanding galvanic separation.

Technical Specifications Matrix

Installation and Wiring Protocol

• Attach the DO802 securely onto S800L mechanical base plates using standard DIN rail configurations.
• Connect field wiring via detachable terminal blocks supporting solid (0.05-2.5 mm²) or stranded (0.05-1.5 mm²) wires.
• Apply a recommended terminal screw torque between 0.5 and 0.6 Nm to prevent high-vibration loosening.
• Strip cable ends precisely to 6-7.5 mm to ensure optimal contact inside the connector block.
• Keep total field cable lengths under 600 meters to maintain signal integrity and prevent capacitive coupling issues.

Commissioning and Maintenance Guidelines

• Power up the node and check that the module status LED illuminates green without flashing errors.
• Test individual relay states using control logic forced variables to verify actuation across all 8 channels.
• Monitor the 24V relay supply voltage converter status regularly through the ModuleBus register mapping.
• Inspect terminal screws annually on high-vibration turbine skids to counteract thermal expansion cycles.

Global PLC Spare HUB's Insight

Deploying legacy S800 nodes in chemical plants often exposes control hardware to aggressive gases and corrosive mist. The DO802 features G3 corrosion classification, protecting internal traces where standard modules fail prematurely. During a recent emergency retrofit at a coastal power station, swapping a failed discrete card for the DO802 (3BSE022364R1) eliminated intermittent channel dropouts caused by salt-air condensation on unisolated circuit buses.

Typical Equipment and Application Scenarios

• Emergency shutdown (ESD) auxiliary tripping loops on large steam turbines.
• Solenoid valve actuation banks in oil and gas midstream compressor stations.
• Heavy industrial furnace burner management systems requiring galvanic isolation.
• Wastewater treatment plant pump interlocking control panels.

Global Logistics, Warranty, and Compliance

• Fulfillment & Shipping: Immediate dispatch within 24-48 hours via trusted couriers including FedEx, UPS, and DHL.
• Warranty Terms: Covered by a comprehensive 12-month operational replacement warranty.
• Global Certifications: CE compliant, marine-certified (ABS, BV, DNV, LR), and RoHS/WEEE compliant.
• Package Inclusions: One factory-sealed DO802 module with pluggable process connectors.

Frequently Asked Questions

What triggers a channel error signal on the DO802 module?

A channel error or module warning trips immediately if the 24V relay supply voltage distributed via the ModuleBus drops out or fails.

Can I disable the relay supply voltage supervision feature?

Yes, system programmers can enable or disable this supervision parameter directly through the configuration software.

What is the maximum permissible ambient temperature for vertical mounting?

When mounted vertically, the maximum ambient temperature rating drops to 40 °C (104 °F) to ensure proper thermal dissipation.

How do I choose between solid and stranded wires for installation?

Use solid wire (up to 2.5 mm²) for fixed, vibration-free panel layouts, and stranded wire (up to 1.5 mm²) with ferrules for mobile or high-vibration skids.
