Overview

The ABB 216GA62/N221 (HESG112799R1) is a high-performance tripping auxiliary relay assembly designed for industrial automation, power protection, and emergency shutdown systems. It delivers fast response times, low power consumption, and reliable contact operation, making it ideal for applications requiring rapid fault isolation and system protection.

This module features up to eight potential-free tripping contacts, configurable for diverse control and protection tasks. It supports surge circuits for high-speed operation and economy circuits to minimize energy usage after activation. An optional tripping logic diode matrix allows direct integration with external signals for advanced protection schemes.

For instance, in a power substation, the 216GA62 can actuate circuit breakers or alarms immediately upon fault detection, ensuring rapid system response and safety.

Technical Data

Typical Applications

• Power Substations: Triggers breakers and alarms in response to protection relay signals.

• Process Automation Systems: Provides fast tripping for emergency shutdown and interlock circuits.

• Energy Monitoring and Control: Interfaces with control logic to isolate faults and maintain system stability.
