ABB 3BSE069053R1 DO818 Digital Output Module  

1. Key Parameters

• Product Model: DO818
• Order Code: 3BSE069053R1
• Product Series: ABB 800xA I/O Series (DCS Digital Output Modules)
• Core Function: 16-channel digital output; transistor (MOSFET) output; DIN rail mounting; galvanic isolation; overload/short-circuit protection; compatible with ABB 800xA DCS.

2. Core Features

• 16-Channel Control: Enables simultaneous control of 16 field actuators, reducing module count in dense DCS control loops.
• Transistor Output: Fast response (≤1ms) and low power loss, suitable for high-frequency switching applications (e.g., fast-acting valves).
• High Isolation: 2.5kVrms galvanic isolation prevents cross-interference and protects the 800xA DCS from field voltage surges.
• 800xA Integration: Auto-detected by the ABB 800xA system, supporting plug-and-play deployment without custom configuration.

3. Application Fields

• Process Control: Triggers solenoid valves and pump contactors in chemical/petrochemical reactor control systems.
• Manufacturing: Controls conveyor actuators and assembly line indicator lights in automotive/electronics production.
• Utilities: Operates switchgear auxiliary contacts and water treatment valve actuators in power plants or municipal facilities.

4. Precautions

• Compatibility: Use exclusively with ABB 800xA DCS; avoid exceeding 0.5A per channel or 4A total current.
• Installation: Separate output wiring from high-power cables (>10A) to reduce EMI; torque terminal screws to 0.5~0.7 N·m.
• Maintenance: Check output switching integrity quarterly; clean terminals monthly (remove dust); replace if overload protection triggers repeatedly.
• Spare Parts: Use genuine ABB 3BSE069053R1 DO818 units—non-genuine modules may cause actuator misoperation or DCS damage.
