ABB HESG324013R0101-216AB61 Binary Output Unit for REG 216 Numerical Generator Protection System

The 216AB61 is designed to transfer signals generated by the activated protection functions to auxiliary relay assemblies for functions such as remote signalling. ABB REG 216 documentation identifies the module as a binary output unit with 32 output channels.

Product Identification

ABB HESG324013R0101 Overview

The HESG324013R0101 reference identifies the ABB hardware associated with the 216AB61 binary output unit. Product listings identify HESG324013R0101 and 216AB61 as the corresponding ABB part number and type designation.

For technical catalogues and inventory records, it is preferable to retain the complete identification ABB HESG324013R0101-216AB61. This combines the ABB part number with the 216-series module designation and makes the product easier to distinguish from other REG 216 components.

216AB61 Binary Output Unit

The 216AB61 is a binary output unit within the ABB REG 216 protection architecture. ABB documentation describes the unit as transferring signals generated by activated protection functions to the auxiliary relays in the 216GA61 output relay unit for remote signalling.

The module contains 32 output channels. These channels are divided between two connectors, with channels CHO01 through CHO16 assigned to the upper connector and channels CHO17 through CHO32 assigned to the lower connector.

The output architecture allows protection signals generated within the REG 216 system to be routed toward the corresponding relay and signalling circuitry.

REG 216 Numerical Generator Protection

The REG 216 is a numerical protection system associated with generator and block-transformer protection. The system uses a modular architecture in which different units provide measurement, processing, input, output and auxiliary functions.

Within this architecture, the 216AB61 provides binary output functions. It therefore works as one component of the overall protection system rather than as a general-purpose programmable logic controller output module.

The exact protection functions and output assignments depend on the configuration of the complete REG 216 installation.

32 Output Channels

One of the key characteristics of the ABB 216AB61 is its 32-channel binary output structure. ABB documentation states that a single 216AB61 unit can control two 216GA61 output relay units.

The output channels are organized into two groups:

• CHO01 to CHO16: upper connector
• CHO17 to CHO32: lower connector

When multiple 216AB61 units are installed in one REG 216 system, the output channels are assigned within the system according to the system configuration. ABB documentation also identifies the first two output channels of the first 216AB61 as reserved for system alarm signals.

Binary Output Function

Binary outputs provide discrete control or signalling states rather than continuously variable analog values. In a protection system, these outputs can be used to communicate the status of protection functions to downstream relay and signalling equipment.

The 216AB61 is specifically designed for this role within the REG 216 architecture. Its outputs are associated with the auxiliary relay assembly rather than being intended as independent field outputs for arbitrary automation equipment.

Connection to 216GA61

The ABB 216AB61 is designed to work with the 216GA61 output relay unit. According to the REG 216 documentation, the 216AB61 transfers protection signals to the auxiliary relays K1 through K16 in the 216GA61 output relay unit for remote signalling.

This relationship is important when identifying the complete protection system because the binary output unit and output relay unit perform complementary functions.

The 216AB61 should therefore be considered within the complete system architecture when reviewing wiring, output assignments or replacement requirements.

Rack Installation

The ABB 216AB61 is a modular component of the REG 216 system. ABB documentation illustrates the binary output unit as one of the modules installed within the REG 216 system equipment rack.

The rack position and channel assignment can be important when maintaining an existing protection installation. The exact system documentation should be consulted before changing module positions or wiring.

System Architecture

The REG 216 architecture contains several specialized modules. ABB documentation identifies modules such as the 216EA61 analog input unit, 216AB61 binary output unit, 216VC62A processing unit and other system components.

This modular design separates measurement, processing and output functions. The HESG324013R0101-216AB61 occupies the binary output portion of this architecture.

Protection Signal Transfer

The 216AB61 receives the output signals generated by the activated protection functions and transfers those signals toward the associated relay assembly. This provides an interface between numerical protection logic and external signalling or switching functions.

Because the output assignments depend on the configuration of the protection system, the physical module reference alone does not define which protection function is assigned to every channel.

Technical Specifications

Relationship Between HESG324013R0101 and 216AB61

The two identifiers in HESG324013R0101-216AB61 refer to the same ABB product designation at different identification levels. HESG324013R0101 is the ABB hardware part number, while 216AB61 is the corresponding module type. Multiple ABB-related product records list these references together.

For product-page optimization and technical inventory management, using both identifiers is recommended because customers may search for either the HESG number or the 216AB61 type designation.

Related REG 216 Components

The ABB REG 216 system includes other modules that should be distinguished from the 216AB61. Related product references include 216DB61, 216EA61, 216GA61, 216VC62A and other 216-series components.

Each module has a specific role within the protection architecture. The HESG324013R0101-216AB61 should therefore not be identified simply as a generic ABB input/output module.

Maintenance and Identification

When documenting the ABB HESG324013R0101-216AB61, the complete part number should be recorded together with the module designation. This helps prevent confusion with other ABB 216-series components.

• Manufacturer: ABB
• Part number: HESG324013R0101
• Module type: 216AB61
• Function: Binary output
• Number of outputs: 32
• System: REG 216
• Associated relay unit: 216GA61
• Application: Numerical generator protection

Where available, the rack position, system configuration and output-channel assignment should also be included in maintenance records.

Replacement Identification

The recommended starting point for identifying this module is the complete reference ABB HESG324013R0101-216AB61. Searching by both HESG324013R0101 and 216AB61 can help distinguish the product from other ABB 216-series modules.

The following information should be compared when identifying a replacement:

• HESG324013R0101
• 216AB61
• REG 216 system compatibility
• Binary output function
• 32-channel output configuration
• Associated 216GA61 relay architecture

A similar-looking ABB 216-series module should not be assumed to be interchangeable without checking the complete system documentation and part-number information.

Industrial Protection Applications

The REG 216 platform is intended for numerical protection applications involving generators and block transformers. The 216AB61 contributes to the output side of this protection architecture by transferring protection signals to the associated relay circuitry.

This makes the module relevant to power-generation installations where protection signals must be communicated to auxiliary relays and external signalling equipment.

The exact functions assigned to the individual output channels are determined by the protection configuration of the specific installation.
