Description Reviews

Yokogawa ANT502-53 Optical ESB Bus Repeater Module

Configured for long-distance optical bus extension in CENTUM VP, CS 3000, and ProSafe-RS systems, the Yokogawa ANT502-53, also cataloged as the ANT502 Optical ESB Bus Repeater Module, provides direct physical/electrical execution. The hardware converts serial ESB control signals into optical pulses for transmission over distances up to 5 km per hop, delivering galvanic isolation and total immunity to field electromagnetic noise between Field Control Units (FCUs) and remote I/O nodes.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

The ANT502-53 module bridges field nodes processing 4-20 mA HART loop protocol signals back to central processing units over long distances without signal degradation. Complete optical isolation prevents ground loop currents from traversing remote cabinets, preserving channel-to-channel isolation on downstream analog input cards and maintaining cold junction compensation (CJC) stability on remote temperature transmitters.

Frequently Asked Questions

Q: What optical connector type and fiber configuration does the ANT502-53 require?

A: The module utilizes standard duplex LC connectors conforming to IEC61754-20 and requires a 2-core optical fiber link operating at a 1.3 um wavelength.

Q: How does the module handle extended communication distances across field control networks?

A: The module acts as an ESB bus repeater slave that converts electrical bus signals to optical signals, permitting noise-free transmission up to 5 km per optical hop.

Field Installation Guidelines

Mount the ANT502-53 into an assigned node slot or DIN-rail base assembly within the enclosure. Ensure that the cabinet grounding point connects directly to the local earth bus to dissipate electrostatic charges.

When routing optical fiber cables, clean all LC connector end-faces prior to insertion. Respect the minimum bend radius specifications of the optical cable to prevent attenuation losses exceeding the permissible 0 to 10 dB margin. Secure 24 VDC power wiring to the primary supply terminals, keeping power conductors separated from optical paths to allow unobstructed access during routine maintenance.
