Description

The ABB SD822 (Order Code: 3BSC610038R1) is a high-performance, space-saving power supply module designed specifically for the ABB AC 800M and S800 I/O product lines. This unit provides reliable 24V DC output power for controllers, sensors, and actuators in industrial automation and process control environments. It is engineered for demanding applications, including those requiring IEC 61508-SIL2 and SIL3 rated solutions.

Features

• Compact design optimized for DIN-rail mounting.
• Class I equipment (requires Protective Earth connection).
• Provides protective separation between primary and secondary circuits.
• Suitable for SELV and PELV applications.
• Integrated protection against over-current (current limiting) and over-voltage (OVP).
• Supports redundant power configurations when paired with an SS822 voting unit.

Applications

• Factory Automation: Powering PLC systems, controllers, and field instrumentation.
• Process Control: Ensuring stable, regulated power for DCS (Distributed Control Systems).
• Building Automation: Supporting HVAC, lighting, and security control infrastructure.
• Machine Control & Robotics: Providing stable 24V DC power to mechanical control systems.

Technical Specifications

Installation Guidelines

• Voltage Selection: Before installation, verify the input voltage switch on the device surface. The unit is factory-set to 230V AC; adjust to 115V AC if required by your local power grid.
• Mounting: Designed for standard DIN-rail mounting. Ensure adequate clearance around the unit for heat dissipation.
• Grounding: As Class I equipment, the module must be connected to a reliable Protective Earth (PE) terminal to ensure safety and EMI compliance.
• Redundancy: For applications requiring power redundancy, the SD822 must be integrated with an appropriate SS822 voting unit.
• Handling: Always power down the system before inserting or removing the module to prevent electrical arcing or damage to the backplane connectors.

FAQs
