Redundant configuration: supports dual redundant system

Double isolation and anti-interference: 500V AC isolation design is adopted between channels and between the system and the site to effectively resist electrical noise and interference and ensure signal stability.

HART protocol communication: Yokogawa AAI143-H00 has built-in HART protocol, which supports remote diagnosis, configuration and two-way communication of equipment.

Industrial-grade environmental adaptation: Yokogawa AAI143-H00 complies with ISA G3 corrosion resistance standards, and some models support a wide temperature range (-20℃~+70℃) to adapt to harsh working conditions; no explosion-proof design (suffix -H00), suitable for non-hazardous areas.

Modular and redundant configuration: Yokogawa AAI143-H00 supports dual redundant system to improve system reliability; compact design is easy to install and expand.

Flexible wiring options: Yokogawa AAI143-H00 provides a variety of wiring methods such as pressure clamp terminals and MIL connector cables to meet the needs of different industrial sites.

Energy and Power: High precision (±16μA) and wide temperature adaptability adapt to power station/new energy equipment status monitoring, ISA G3 corrosion resistance ensures long-term stability.

Chemical Petroleum: Non-explosion-proof design (-H00) but double isolation (500V AC) meets the anti-interference requirements of non-hazardous areas, and redundant configuration improves reliability.

Environmental Water Treatment: Modbus protocol integrated DCS system, industrial-grade protection (IP65) supports humid/corrosive environment data collection.

Rail Transit: Redundant design and modular structure adapt to signal system monitoring, high reliability ensures transportation safety.

Electronic Communications: High-density multi-channel design supports real-time monitoring of data center/base station equipment status, and fast response meets high-speed requirements.
