Yokogawa offers a comprehensive range of I/O modules compatible with systems like the CENTUM series Distributed Control Systems (DCS) and the STARDOM network-based control systems. These modules are engineered to meet the demanding requirements of process industries, ensuring seamless integration and optimal performance.
Types:
-
Analog Input Modules: Capture continuous signals such as temperature, pressure, and flow rate. Models like the AAI141-H support 16-channel current inputs (4 to 20 mA) with HART communication capabilities.
-
Analog Output Modules: Provide continuous control signals to actuators and other devices. For instance, the AAI543-H offers 16-channel current outputs (4 to 20 mA) with HART communication.
-
Digital Input Modules: Detect discrete signals, such as equipment status or binary sensor outputs. The F3XD16-3F module offers 16-point DC voltage inputs with photocoupler isolation.
-
Digital Output Modules: Send discrete control signals to devices like relays or indicators. The F3YD64-1A module provides 64-point transistor outputs suitable for various applications.
-
Analog/Digital Combination Modules: Handle both analog and digital signals within a single unit. The S2MMM843 module offers configurable analog and digital I/O functions per channel, enhancing flexibility.
Technical Features:
-
High-Speed Processing: Modules like the F3AD08-5R analog input module achieve conversion speeds as fast as 50 μs per point, ensuring timely data acquisition.
-
Scalability: Modular design allows for easy expansion, accommodating up to 64 input/output points per module, depending on the type.
-
Isolation: Photocoupler isolation between input/output terminals and internal circuits enhances noise immunity and protects against electrical interference.
-
HART Communication: Certain analog modules support HART protocol, enabling simultaneous analog and digital communication with field devices for enhanced diagnostics and configuration.
