Yokogawa ANB10D-415/CU2T ESB Bus Node Unit

Hardware Specifications

Process Control I/O Communication Characteristics

The ANB10D-415/CU2T operates as an ESB interface node between field I/O modules and the Field Control Unit. Moreover, it transfers analog I/O and contact I/O signals through the ESB bus communication path while providing the required module power distribution function.

The unit supports Yokogawa DCS architectures using FCU-based control configurations. In addition, the ESB Bus Node Unit requires EC401 or EC402 ESB Bus Couple Modules for FCU connection. The module placement defines the bus configuration mode, where slot 7 and slot 8 support redundant installation and slot 7 alone supports single configuration.

The Yokogawa DCS I/O architecture supports process instrumentation interfaces including analog measurement loops and contact status signals. Therefore, installation design must follow the specified FCU slot allocation and ESB bus connection method.

Frequently Asked Questions

Q: Which FCU modules are required to connect the ANB10D-415/CU2T to an FCU?
A: The unit requires an ESB Bus Couple Module EC401 or EC402 installed in the FCU. The couple module occupies slot 7 and slot 8 for dual configuration or slot 7 only for single configuration.

Q: What power supply options are available for the ANB10D-415/CU2T?
A: The unit supports 100-120 VAC, 220-240 VAC, and 24 VDC power supply configurations according to the selected suffix code.

Q: Does the ANB10D-415/CU2T provide field signal interface functions?
A: Yes. The unit communicates analog I/O and contact I/O signals from field devices to the FCU through the ESB bus interface.

Field Installation Guidelines

Install the ANB10D-415/CU2T in a compatible 19-inch rack using the specified M5 x 4 screw mounting method. Use the supplied insulation bush when required by the rack installation configuration.

Connect the ESB Bus Node Unit to the FCU through EC401 or EC402 ESB Bus Couple Modules. Verify correct slot allocation before energizing the system, especially when configuring redundant ESB bus connections.

Route power wiring and ESB communication cables separately from high-voltage switching circuits to reduce electrical interference. Maintain proper cable shielding and grounding practices according to the Yokogawa installation documentation.

Before operation, confirm the selected power supply voltage matches the installed suffix configuration. Check all I/O module connections, rack mounting conditions, and FCU communication status during commissioning.
