YOKOGAWA ANT502-5E

ANT502 is the optical ESB Bus Repeater Slave Module used to transport ESB bus communication over optical fiber. In the 5 km repeater configuration, the optical path extends ESB bus transmission between the master-side repeater and the slave-side repeater.

The module is intended for optical ESB bus architectures using chain or star connections. ANT502 is installed as a slave-side module in an Optical ESB Bus Node Unit and can also be installed in an Optical ESB Bus Repeater Unit.

The architecture is particularly useful where the electrical ESB bus segment must be extended through an optical link while keeping the field-control network structure organized around the repeater units.

The optical interface uses LC connectors compliant with IEC 61754-20.

The specified fiber arrangement uses two optical fiber cores and quartz single-mode optical fiber.

The maximum permissible optical loss is specified as 0 to 10 dB at 1.3 μm, with a maximum fiber length of 5 km for the optical repeater hop.

ANT502 can be installed in an Optical ESB Bus Node Unit and in an Optical ESB Bus Repeater Unit.

For single configuration, the ANT502 installation position in the Optical ESB Bus Node Unit is B1. In the Optical ESB Bus Repeater Unit, supported positions include IO1, IO3, IO5, IO7 and B1.

For dual-redundant configuration, the ANT502 positions are B1 and B2 in the Optical ESB Bus Node Unit, while the repeater-unit arrangement can use IO1 to IO8 and B1/B2.

ANT502 uses the A2EE3A ESB Bus Adapter family for connection arrangements.

A connector unit can be configured for ESB bus connection or with an ESB bus terminator.

An HKU interface variant can transmit cabinet environmental information through the optical ESB bus so that the FCU can monitor the connected cabinet conditions and HKU operating status.

The ANT401 Optical ESB Bus Repeater Master Module provides the master-side optical repeater function. ANT502 operates as the corresponding slave-side module in the 5 km optical repeater architecture.

ANT502 provides the optical ESB bus slave-side function. The ANT502 family is intended for optical ESB bus repeater configurations extending communication through optical fiber.

The A2EE3A family provides the connector-unit interface for ANT502. Available configurations distinguish ESB bus connection, termination and HKU interface arrangements.

ANT502 is installed as standard in an Optical ESB Bus Node Unit and can also be installed in the Optical ESB Bus Repeater Unit, depending on the system arrangement.

Send the exact part number, required quantity, destination and required date. For system matching, you may also include the machine or control-system name and the existing module configuration.

ANT502 is the slave-side optical ESB bus repeater module for the 5 km class. A complete repeater link uses the corresponding master-side architecture and optical fiber connection. The specified maximum transmission distance is 5 km for one hop, so the actual system topology and cable routing should be checked against the intended installation.

The optical interface uses LC connectors compliant with IEC 61754-20. The specified optical fiber is quartz single-mode fiber, with two required fiber cores. The specification gives a maximum permissible optical loss of 0 to 10 dB at 1.3 μm and a maximum length of 5 km for the applicable optical repeater hop.

Yes, the ANT502 architecture supports dual-redundant installation. Yokogawa specifies that the two modules for ESB bus 1 and ESB bus 2 should be the same module type. The paired modules are installed in continuous slots, with ESB bus 1 in an odd-numbered slot and ESB bus 2 in an even-numbered slot.

Yes. ANT502 uses the A2EE3A ESB Bus Adapter family. The adapter configuration distinguishes a connector unit for ESB bus connection, a connector unit with terminator, and variants with or without the HKU interface. The required configuration therefore depends on whether the module is being connected to the ESB bus, terminated at that position, or used for cabinet environmental monitoring.

Confirm the complete model and adapter configuration, especially the ESB bus connector or termination arrangement and any HKU interface requirement. For dual-redundant systems, confirm that the two ESB bus modules use the same module type and occupy the correct paired slots. Where a replacement involves a different ANT502 suffix family, the applicable system configuration and replacement requirements should be verified before installation.
