Yokogawa Base Plate A2BN3D-09030 for adaptor (for N-IO, 16-channel)

Base plate for adaptor (A2BN3D)

This base plate communicates with a node interface unit via an F-SB bus by connecting a field signal to the terminal or the connector on the Base plate for adaptors.
The Base plate for adaptors, one of the components of the N-IO I/O unit (for Adaptor) which is defined as A2ZN3D for the system model, enables to mount I/O modules and various I/O adaptors depending on the signal types. The I/O modules can be mounted in a single or dual-redundant configuration. Channels on the base plate are available to connect up to 16 I/O adaptors. All channels have a disconnection function by making an I/O adaptor half-inserted that can disconnect the signal line between the field terminal, the I/O module, and the I/O adaptor. The base plate has a system power supply and field power supply interface and has a function to supply power to the I/O modules and I/O adaptors from the node interface unit via the power supply cable for base plates (A2KPB00) as well as to supply field power to the inside of the I/O adaptors by connecting the specified power line.
