Description
ABB 216DB61 HESG324063R100/H Product Description
Product Overview
ABB 216DB61 HESG324063R100/H is a binary input/output and tripping unit belonging to ABB’s legacy REG 216 generator protection and control architecture. The 216DB61 provides discrete signal interfacing and dedicated tripping functions, allowing protection logic to exchange status information with external auxiliary relays while driving trip circuits. Published references identify the unit as having 16 digital inputs and 8 monitored outputs, with the outputs arranged for two-pole control of auxiliary tripping relays.
The ABB 216DB61 is designed for protection-oriented applications rather than conventional PLC automation. Its digital inputs receive signals from the associated auxiliary relay circuitry, while the output section provides monitored tripping commands. LEDs indicate activated inputs and outputs, helping maintenance personnel diagnose the state of protection circuits. The HESG324063R100/H suffix should be matched carefully when replacing installed hardware because different revisions and related 216-series modules may have different functions.
For generator protection maintenance, 216DB61 HESG324063R100/H provides a practical module-level replacement for an existing REG 216 installation. Maintaining the correct hardware preserves established protection wiring and system configuration and can reduce the engineering effort required to restore a failed protection channel.

The strongest available technical reference specifies 8 outputs for two-pole control of auxiliary tripping relays and 16 digital inputs, with activated inputs and outputs indicated by LEDs. Some aftermarket listings give inconsistent voltage/current and communication specifications, so those values should not be treated as authoritative for engineering without checking the original ABB documentation.
Main Features and Advantages
16 Digital Inputs
The ABB 216DB61 provides 16 digital input channels for receiving discrete protection and status signals from the associated auxiliary relay assembly. In the REG 216 architecture, selected inputs can be used to externally enable or block tripping functions, providing flexibility when implementing generator protection schemes.
Eight Monitored Trip Outputs
The output section contains eight outputs intended for two-pole control of auxiliary tripping relays. This arrangement is particularly important in generator protection because trip circuits must be controlled reliably and their operating state monitored.

Output Monitoring
The 216DB61 HESG324063R100/H incorporates monitored output amplifiers. This provides an additional layer of supervision over the trip-output circuitry, helping maintenance personnel identify abnormalities in the protection output path rather than relying solely on external indications.
LED Status Indication
Activated inputs and outputs are indicated by front-panel LEDs. This is a practical advantage during commissioning and troubleshooting because technicians can quickly determine whether a protection signal has reached the module and whether the corresponding output has been activated.
Modular Protection Architecture
The 216DB61 occupies one rack division within the modular protection system. Its replaceable-board architecture allows a defective input/output or tripping unit to be serviced independently, reducing the need to replace an entire protection cabinet.
Flexible Protection Scheme Integration
ABB’s REG 216 architecture uses combinations of software functions and hardware modules to adapt the protection system to different primary equipment and protection schemes. The 216DB61 provides the discrete I/O and tripping interface needed to connect these protection functions to external relay and trip circuitry.
Application Fields
ABB 216DB61 HESG324063R100/H is primarily used in generator protection systems where reliable discrete signal handling and monitored tripping are required. In thermal power plants, it can interface the REG 216 protection system with auxiliary relays and generator trip circuits associated with turbine-generator units.
In hydroelectric power stations, industrial cogeneration plants and captive power facilities, the 216DB61 ABB can provide the binary signal and trip interface required by legacy REG 216 protection schemes. Its monitored outputs are particularly useful where generator fault conditions must result in dependable actuation of external tripping relays.
The module can also be used in other ABB protection installations based on the compatible 216-series architecture. Typical signals include protection relay status, external trip/block commands and auxiliary equipment feedback. The 16-input/8-output arrangement provides a practical interface between electronic protection logic and conventional hardwired relay circuits.
For maintenance departments, HESG324063R100/H is best handled as an exact-match replacement part. The complete model, hardware suffix and existing protection-system configuration should be verified before installation, especially because the 216 family contains visually similar modules with different functions.
