Product Description:
The ANB10D-427/CU2N ESB Bus Node Unit has an interface function that communicates the analog I/O signals and contact I/O signals of a field with a Field Control Unit (FCU) via an ESB bus, as well as a function that supplies power to the I/O Modules. This node units are connected to FCU via an ESB bus. 

It is a dual-redundant power supply configuration to enhance system reliability and ensure continuous operation even in the event of a power source failure.The unit operates with a 220–240 V AC power supply, making it suitable for standard industrial power environments. It supports stable energy distribution to connected I/O modules.

Application:
Oil and gas: Offshore platforms, oil production facilities and LNG (liquefied natural gas) receiving stations.
Petrochemicals: Ethylene, synthetic ammonia or refining plant equipment.
Electricity industry: Auxiliary control (BOP) and water treatment systems for large thermal power plants, nuclear power plants and combined cycle power plants.
Papermaking and water treatment: Distributed data processing for large papermaking units or municipal wastewater treatment plants.
