Product Description

Overview

The Yokogawa ALR111-S00 is a robust RS-232C serial communication module designed for integration with CENTUM VP and CENTUM CS 3000 Distributed Control Systems. This module enables precise, high-speed data exchange between Field Control Stations (FCS) and peripheral devices such as PLCs, chromatographs, or digital weighing scales. Its standard configuration does not include explosion-proof features or special conformal coating beyond industrial-grade requirements.

Functional Highlights

  • High-Speed Data Handling: Efficiently manages large volumes of data without impacting control loop performance.

  • Flexible Integration: Communication Builders allow mapping of external device data (e.g., Modbus) to FCS functional blocks.

  • Hot-Swap Capability: Replaceable under maintenance conditions without shutting down the system.

  • Diagnostic LEDs: Front-panel indicators provide immediate status on activity, health, and errors.

Applications

The ALR111-S00 is ideal for industrial environments where reliable point-to-point serial communication is required, including:

  • Process monitoring with PLCs

  • Data collection from analytical instruments

  • Integration with weighing and batching equipment

Comparison with ALR121

While ALR111-S00 supports RS-232C for point-to-point connections, the ALR121 variant offers RS-422/RS-485 for longer distances (up to 1200 meters) and multipoint networks, making it suitable for distributed sensor systems.

FAQ

Q: Can this module handle distances beyond 15 meters?
A: RS-232C is limited to 15 meters; use RS-422/RS-485 (ALR121) for longer runs.

Q: Is the module hot-swappable?
A: Yes, replacement is possible under specified maintenance procedures without powering down the system.

Q: What protocols are supported?
A: Both standard protocols and user-defined protocols via ALRECU software.
