Overview

The ABB 216GA61/N211 (HESG112800R1) is a high-performance output relay module from ABB’s REG 216 series, widely used in power generation, transmission, and industrial automation systems. It delivers potential-free relay outputs for triggering alarms, operating breakers, or initiating control sequences based on system events.

The module supports up to 16 independent auxiliary relays, each capable of fast, reliable operation. It features DIN rail or screw mounting, long mechanical and electrical life, and robust design suitable for demanding industrial environments.

For instance, in a high-voltage substation, the 216GA61/N211 can actuate trip coils or annunciators when faults are detected by protection relays, ensuring rapid response and system safety.

Technical Data

Typical Applications

• Substation Protection Systems: Activates trip coils, alarms, and interlocks based on relay logic.

• Power Generation Facilities: Interfaces with turbine and generator protection schemes.

• Industrial Automation Panels: Provides reliable output switching for control sequences and fault responses.

• Process Safety Systems: Triggers emergency shutdown or isolation mechanisms in hazardous environments.

• Smart Grid and Energy Management: Supports distributed control and fault signaling in modern grid architectures.

The 216GA61/N211 is also widely used in retrofit projects, replacing aging relay modules with modern, high-speed alternatives.
