Main Features and Advantages

The Yokogawa ANR10D delivers exceptional safety performance through its robust relay design and comprehensive diagnostic capabilities. The module features heavy-duty Form C (SPDT) contacts with high switching capacity, capable of handling significant electrical loads up to 5A at 250V AC, making it suitable for direct control of various field devices without requiring additional contactors or amplifiers. The Yokogawa ANR10D incorporates continuous self-diagnostics that monitor contact status, coil operation, and internal circuitry, ensuring that any potential failure is detected before it can compromise the safety function. This high diagnostic coverage, exceeding 90%, provides confidence in the module’s ability to perform its safety function when required.

Enhanced safety architecture: The Yokogawa ANR10D is designed with a de-energized-to-trip philosophy, ensuring that safety actions are executed even in case of power loss. The module’s high isolation rating (1500V AC) between field circuits and the control system provides superior protection against electrical noise, surges, and ground potential differences. This isolation, combined with the robust relay design, ensures reliable operation in harsh industrial environments where electrical interference could affect less robust components. The Yokogawa ANR10D supports redundant configuration options, allowing for hot standby arrangements that maintain safety protection even during maintenance operations, significantly enhancing system availability.

Operational and maintenance advantages: The Yokogawa ANR10D offers significant maintenance benefits through its advanced diagnostic capabilities and hot-swappable design. The module provides detailed status information for each channel, including contact wear indication, predictive maintenance data, and real-time performance monitoring. The hot-swap capability allows for module replacement without system shutdown, dramatically reducing maintenance downtime and associated costs. The module’s integration with Yokogawa’s engineering tools simplifies configuration, testing, and documentation, supporting compliance with safety lifecycle management requirements and reducing overall cost of ownership while maintaining the highest safety standards.

Application Field

The Yokogawa ANR10D is deployed across multiple high-hazard industries where safety instrumented systems are mandatory for risk reduction. In oil and gas facilities, the module serves in critical applications including emergency shutdown systems on offshore platforms and refineries, where it controls safety valves, shutdown devices, and emergency ventilation systems. The Yokogawa ANR10D‘s robust relay contacts and high switching capacity ensure reliable operation of these critical safety functions even in the challenging environments encountered in oil and gas production and processing facilities, where equipment failure could lead to catastrophic consequences.

Petrochemical and chemical processing plants utilize the Yokogawa ANR10D in reactor emergency cooling systems, emergency pressure relief systems, and critical interlock circuits. The module’s high reliability and diagnostic capabilities ensure that safety actions are executed precisely when process parameters exceed safe operating limits, preventing runaway reactions, equipment damage, and potential environmental incidents. In power generation, particularly in nuclear and conventional thermal power plants, the Yokogawa ANR10D provides safety-critical control of turbine emergency stop systems, boiler safety valves, and emergency core cooling systems where reliable operation is essential for public safety and asset protection.

The pharmaceutical, specialty chemical, and other process industries also benefit from the Yokogawa ANR10D‘s capabilities for safety applications where reliable isolation of process sections is critical to maintaining safe operating conditions. In each application, the module provides the reliable output switching necessary for implementing effective safety functions that protect human life, environmental assets, and capital equipment while ensuring regulatory compliance and operational excellence in some of the world’s most demanding industrial environments.
