Yokogawa PFCD-S5520 Duplexed Field Control Station

The Yokogawa PFCD-S5520 is a duplexed field control station (FCS) that is part of the Yokogawa CENTUM CS and CENTUM VP distributed control systems (DCS). It is designed to provide a high level of reliability and availability for critical process control applications.

The PFCD-S5520 consists of two redundant FCS racks, each of which can contain up to 12 single or 6 redundant I/O modules. The two FCS racks are interconnected by a high-speed duplexed communication bus. This allows the PFCD-S5520 to continue operating even if one of the FCS racks fails.

The PFCD-S5520 supports a wide range of I/O modules, including analog input modules, analog output modules, digital input modules, and digital output modules. This allows the PFCD-S5520 to be used to control a wide variety of process devices, such as sensors, actuators, and valves.

The PFCD-S5520 is also equipped with a number of features that make it easy to install and maintain, such as:

• A modular design that allows for easy expansion and maintenance.

• A hot-swappable power supply that allows for uninterrupted operation during power supply maintenance.

• A built-in diagnostic system that helps to identify and troubleshoot problems.

Technical specifications:

• Power supply: 220-240VAC, 50/60Hz, 300VA
