YOKOGAWA Models ANB10S, ANB10D, ANR10S, ANR10D Node Units (for FIO)

GENERAL

The 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.

The ANB10S and ANB10D are called “ESB Bus Node

Units” (Local Nodes) because they are connected

directly to a FCU via an ESB bus, whereas the

ANR10S and ANR10D are called “ER Bus Node Units”

(Remote Nodes) because they are connected to an

EB401 (ER Bus Interface Master Module) installed in

an ESB Bus Node Unit via an ER bus.

A power supply module, bus interface module and I/O

module are installed in the node unit.

A single or dual-redundant configuration can also

be selected for the node unit. For details on the

I/O modules, refer to the General Specifications of

the I/O Modules (for FIO) (GS 33M50F25-40E, GS

33M50F30-40E, GS 33M50F40-40E, GS 33M50G10

40E, GS 33M50G20-40E).
