ABB 216BM61B

The ABB 216BM61B (HESG448267R1021 / HESG448268R1 series references) is associated with ABB's RE.216 / REG 216 numerical protection system. Available technical references identify the 216BM61B as a communication interface module used for exchanging data between protection equipment and external systems. Its application depends on the specific hardware variant and ordering number.

The module is intended for industrial protection and control environments where dependable communication is required for monitoring, signaling, and coordination with other equipment.

2. Core Functions

• Communication interface: Supports data exchange between compatible protection-system equipment and external devices.

• Protection-system integration: Works as part of a modular protection and control architecture.

• Serial communication: Variant-specific documentation identifies interfaces associated with RS-232C communication.

• Optical-fiber connectivity: Certain ordering variants are documented with optical-fiber interfaces for interbay or process-bus communication.

3. Design Features

• Modular design: Designed for integration into compatible ABB protection-system equipment.

• Communication flexibility: Different ordering variants support different communication interfaces and connection types.

• Industrial reliability: Intended for continuous operation within electrical protection and control installations.

• System-specific compatibility: Hardware version, interface type, and configuration must match the installed protection system.

4. Hardware Composition

The 216BM61B is associated with a communication-interface function in the ABB RE.216 protection platform. Depending on the exact variant, the relevant hardware and connections may include:

• Communication interface circuitry

• Serial communication connections

• Optical transmitter and receiver interfaces on applicable versions

• Plug-in connections for integration with compatible system equipment

The exact connector arrangement and hardware configuration should be verified against the complete ordering number.

5. Typical Applications

• Electrical substation protection and monitoring

• Power generation and distribution systems

• Industrial electrical protection installations

• Communication between protection equipment and supervisory systems

• Legacy ABB RE.216 / REG 216 system maintenance and replacement

6. Maintenance Considerations

1. Verify the complete ABB part number and suffix before ordering a replacement.

2. Confirm whether the installed version uses an RS-232C or optical-fiber interface.

3. Inspect connectors, fiber-optic cables, and communication wiring for damage.

4. Check system configuration and communication settings after replacement.

5. Follow the applicable ABB protection-system service procedures and isolate equipment safely before maintenance.

7. Overall Evaluation

The ABB 216BM61B is a legacy industrial protection-system communication component associated with ABB's RE.216 / REG 216 platform. Its principal value is maintaining communication functionality within existing protection installations.
