Technical Specifications
Main Features and Advantages
The Yokogawa ANT401-50 S1 is specifically designed to enhance the efficiency and reliability of a CENTUM VP system’s wiring infrastructure. One of its key features is the use of screw terminals, which provide a durable and secure connection that is less prone to loosening from vibration or environmental factors. The terminal board’s compact and modular design allows for high-density wiring in a cabinet, maximizing space and simplifying panel layout. The clear, silkscreen-printed labeling on the ANT401-50 S1 for each terminal point reduces the risk of human error during wiring and greatly speeds up the installation process.
Seamless Integration: The terminal board is designed to be a perfect fit for its corresponding I/O module, such as the Yokogawa AAI141 analog input module. This plug-and-play design simplifies assembly and ensures a reliable connection every time, minimizing the potential for signal loss or noise interference. The board’s hot-swappable capability allows for the replacement of a faulty I/O module without disrupting the field wiring, which is a major advantage for maintenance and troubleshooting. The ANT401-50 S1 is a simple but critical component that provides the physical backbone for accurate and reliable signal acquisition.
Application Field
The Yokogawa ANT401-50 S1 is primarily used in industrial automation and process control applications that employ the CENTUM VP DCS. Its main application fields are in:
- Process Control: Providing a clean wiring interface for analog signals from temperature sensors, pressure transmitters, and flow meters in chemical plants, oil refineries, and pharmaceutical facilities.
- Power Generation: Used in power plants for connecting instrumentation that monitors critical parameters like boiler temperature, turbine speed, and fluid flow.
- Manufacturing and Automation: In factories where it connects analog sensors on machinery to the control system for data acquisition and process monitoring.
- Water and Wastewater Treatment: Used to wire sensors that measure levels in tanks, chemical concentration, and pH. The Yokogawa ANT401-50 S1 is a foundational component for organizing field signals and ensuring they are accurately transmitted to the main control system.

Installation and Maintenance
Pre-installation preparation: Before installing the Yokogawa ANT401-50 S1, ensure that the corresponding I/O module is correctly inserted into the node cabinet. The ANT401-50 S1 is then connected to the I/O module via its connector. All field wiring should be routed and labeled according to the plant’s wiring diagrams before being terminated to the screw terminals on the board.
Maintenance recommendations: Routine maintenance for the ANT401-50 S1 is minimal. The main activity is to periodically check the tightness of the screw terminals to ensure all connections remain secure and to inspect the wires for any signs of wear or corrosion. The design of the board allows for the I/O module to be disconnected and replaced without needing to disturb the field wiring, greatly simplifying troubleshooting and module replacement.
