Product Description

Overview

The ANT502-5E is a high-speed Optical ESB Bus Repeater (Slave Module) designed for CENTUM VP and STARDOM control systems. It extends the Enhanced System Bus (ESB) via fiber optics, allowing remote I/O nodes to communicate over distances up to 5 km without compromising signal speed or reliability.

Functionality and Applications

• Converts optical signals from a Master Module into ESB electrical signals, enabling remote field connections.

• Supports chain and star network topologies, ideal for large industrial plants and distributed control architectures.

• Ensures deterministic communication with minimal latency for real-time process control.

• Provides electrical isolation via fiber optics, protecting against EMI, ground loops, and lightning surges.

• Compatible with ANB11 Node Units and ANT10U Repeater Units for flexible installation.

Key Features

Long-Distance Optical Transmission

• Supports up to 5 km per hop using quartz single-mode fiber.

• Enables cascading of multiple modules for extended networks.

High-Speed Deterministic Communication

• Operates at the ESB bus native speed (~128 Mbps), maintaining remote I/O performance equivalent to local connections.

• Low-latency signal conversion preserves real-time control loop integrity.

Redundancy and Reliability

• Dual-redundant configuration ensures uninterrupted communication in case of module or fiber path failure.

• Optional HKU interface provides monitoring of cabinet environmental conditions for preventive maintenance.

Maintenance-Friendly Design

• Hot-swappable module allows replacement without system shutdown.

• Compact form factor simplifies integration in standard control cabinets.

Technical Specifications

Design Note

The -5E suffix indicates the module supports 5 km transmission distance and compliance with regional safety or explosion-protection standards as required.
