Product Applications

Power and Energy Management: This is its core application area. It is primarily used in control systems for gas turbines, steam turbines, and wind turbines (such as the GE Vernova system) to monitor turbine status, valve open/close positions, trip protection signals, and electrical system status feedback.

Oil and Gas: Used in distributed control systems (DCS) for large oil refineries, natural gas pipelines, and offshore drilling platforms to collect emergency shutdown (ESD) trigger signals and critical switching quantities such as pressure and valve limits.

Heavy Industrial : Integrated into large PLC or DCS automated production lines, CNC machine tools, and industrial robot systems to perform electrical isolation and signal conversion for remote sensors and actuators.

Metallurgy and Mining: Applied to blast furnace control, steel rolling production lines, and mine hoist safety monitoring systems to ensure accurate transmission of safety interlock signals in high-temperature and high-electromagnetic interference environments.

Water and Municipal Infrastructure: Used for centralized pump station control in large-scale water supply, sewage treatment, heating, and gas pipeline networks to monitor the start/stop of pumps and fans and the opening/closing status of valves in real time.
