Product Description

The Yokogawa AIP171 is a dedicated Transceiver Control Module designed to manage and optimize communication across Yokogawa’s V net networks. It serves as the central control unit for V net repeater devices, ensuring high-speed, accurate, and reliable data transmission between distributed network segments in CENTUM CS and CENTUM VP Distributed Control Systems (DCS).

The module is typically mounted in dedicated interface racks or repeater files, playing a critical role in maintaining the deterministic performance required for real-time industrial control.

Key Features

• High-Speed V net Control: Maintains signal integrity across long-distance network segments with a response time of under 100 milliseconds.

• Signal Accuracy: Processes transceiver data with ±1% accuracy to ensure precise control signal transmission.

• Industrial-Grade Design: Provides galvanic isolation between field-side and bus-side circuits to protect central controllers from electrical surges.

• Real-Time Diagnostics: Equipped with front-panel LEDs showing Power (PWR), Communication Status, and Fault/Error indicators.

• Self-Monitoring: Continuous internal hardware checks alert the system to failures or malfunctions, preventing network downtime.

• Environmental Resilience: Operates in temperatures from −10°C to +60°C and can tolerate non-condensing humidity conditions from 10–90%.

Technical Specifications

Applications

The AIP171 is essential in plants using Yokogawa V net architecture where long-distance communication or signal amplification is required. Typical installations include CENTUM CS and VP networks in chemical, power, and process automation facilities. It allows operators to extend network reach and maintain real-time performance without compromising reliability.
