ABB 216DB61 HESG324063R100 HESG216882 A

ABB 216DB61 is an older-generation binary input/output unit / I/O circuit board associated with ABB’s REC 216 protection and control platform. ABB documentation references the 216DB61 specifically as a “Binary input and output unit”, with the PCB component side corresponding to HESG 324 063.

Product Positioning

• Manufacturer: ABB
• Model: 216DB61
• Part No.: HESG324063R100
• PCB designation: HESG216882/A
• Product type: Binary input/output unit / PC board
• System family: ABB REC 216 protection and control equipment

Core Functions

The 216DB61 is used for handling binary/digital signals within the protection and control system. Its main role is to interface discrete field signals with the REC 216 system, allowing equipment status, alarms, interlocks and control-related signals to be processed.

The available documentation is particularly useful here because it identifies 216DB61 directly as the binary input and output unit, rather than simply a generic controller board.

Design Features

• Industrial-grade PCB construction for protection/control applications.
• Designed as part of the modular REC 216 architecture.
• Provides binary signal interfacing between external equipment and the protection/control system.
• The HESG324063 designation identifies the corresponding PCB/component side in ABB documentation.

Hardware Composition

The assembly is commonly identified by the combination:

216DB61 → HESG324063R100 → HESG216882/A

Different suppliers may describe the same item as a PC board, binary I/O unit, or binary output/input module, so these descriptions should not be treated as different products without checking the actual nameplate.

Typical Applications

The 216DB61 is principally associated with electrical power-system protection and control, particularly REC 216 installations. Typical functions can include:

• Circuit-breaker and switchgear status monitoring
• Protection-system binary signals
• Alarm/status indication
• Interlocking signals
• Control commands
• Substation automation interfaces

Maintenance Considerations

Because this is an older/discontinued-generation ABB component, replacement work should be performed by matching the complete part number, not just “216DB61.” Market listings also identify the part as discontinued/obsolete.

For replacement, verify:

1. 216DB61
2. HESG324063R100
3. HESG216882/A
4. PCB revision/version
5. Connector arrangement
6. Existing REC 216 hardware configuration

Overall Evaluation

ABB 216DB61 is best understood as a legacy REC 216 binary I/O circuit board/unit used in ABB power-system protection and control equipment. The strongest identification is the combination 216DB61 + HESG324063R100 + HESG216882/A, which multiple sources associate with the same ABB board.
