Product Overview

The 216GA61/N211 (ABB Part Number HESG112800R1) is an industrial-grade output relay assembly engineered for the REG 216 protection series. This module serves as a high-density command interface, providing 16 independent potential-free (dry) contacts to execute critical control sequences, trigger annunciators, or drive trip coils in power generation and distribution networks. Built to withstand the rigorous electromagnetic environments of high-voltage substations, the 216GA61/N211 ensures that logic-level protection signals are translated into robust physical switching actions with exceptional mechanical and electrical longevity.

Industrial Application Scenarios

The 216GA61/N211 is a foundational component in automated grid protection and complex industrial logic. In thermal and hydroelectric power plants, it interfaces directly with turbine control systems to manage protection interlocks. Within smart grid architectures, these modules facilitate distributed fault signaling and automated load shedding. Because of its high contact density (16 channels in a slim profile), it is the preferred choice for retrofitting aging control panels where space is limited but high-output counts are required to replace multiple discrete legacy relays.
