Yokogawa AIP571/S2 Electrical RIO Transceiver Module

Overview

The Yokogawa AIP571/S2 is an electrical Remote I/O (RIO) transceiver module developed for Yokogawa CENTUM distributed control systems. It acts as the communication interface between Field Control Units (FCUs) and remote I/O nodes, ensuring deterministic and reliable signal transmission across the RIO network.

Designed for continuous industrial operation, this module supports high-speed electrical communication over Vnet/RIO architectures and is optimized for compact cabinet installations where space efficiency and signal integrity are critical.

Primary Function

The AIP571/S2 transceiver converts and manages electrical RIO communication signals between the FCU and connected remote I/O stations. It ensures synchronized data exchange for process signals, status information, and control commands within CENTUM VP and CENTUM CS platforms.
