Product Description
The ANT401-50 is a high-speed optical communication interface designed to serve as the "Master" side repeater for the Extended System Bus (ESB) in Yokogawa Centum VP Distributed Control Systems (DCS). This module converts electrical bus signals into optical data, enabling long-distance transmission between the Field Control Unit (FCU) and remote I/O nodes. Its optimization for high-performance optical links (indicated by the "50" designation) eliminates the limitations of electromagnetic interference (EMI) and distance constraints that affect traditional copper cabling in large-scale industrial environments.

Operational Utility and Engineering Logic
The ANT401-50 is crucial for large-scale industrial facilities, such as refineries, offshore platforms, and chemical complexes, where I/O stations are located far from the central processing unit. By utilizing fiber optics, the ANT401-50 offers complete galvanic isolation, protecting the core system from lightning-induced surges and high-voltage transients. The compact design (3.2 cm width) enables engineers to save valuable cabinet space while ensuring efficient communication without sacrificing safety or throughput.
Functional Comparison: ANT401-50 vs. ANT401-20
Both modules are designed with the same physical chassis, but the ANT401-50 is specifically tuned for longer-distance communication (up to 5 km), compared to the ANT401-20. The ANT401-50 features a higher power budget in its internal optical transceiver, making it the preferred option for large-scale industrial applications that require millisecond-level determinism in Yokogawa's control logic.
FAQ
Q: Is the ANT401-50 a standalone unit?
A: No, the ANT401-50 (Master) must be paired with a corresponding Slave module (e.g., ANT502 series) at the remote I/O site to complete the optical communication link.
Q: Does this module support redundant configurations?
A: Yes, in high-availability DCS setups, two ANT401-50 modules are often installed in a duplexed configuration to prevent loss of control in the event of an optical fiber fault.
