Yokogawa Base Plate A2BN5D for Barrier (for N-IO, P+F Barrier)
A2BN5D Base Plate for Barrier
This base plate communicates with the node interface unit via an F-SB bus by connecting a field signal to a terminal on the I.S. barrier mounted on.
The Base plate for barrier, one of the components of the N-IO I/O unit (for Barrier) which is defined as A2ZN5DC for the system model, enables to mount I/O modules and various I.S. barriers from Pepperl+Fuchs GmbH (P+F). This base plate has a field connection terminal (spring clamp terminal) for connecting the field signals. If it is necessary to disconnect the signal line between the field device and the I.S. barrier, disconnect the signal line outside the base plate for barrier.

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.S. barriers. The base plate has a system power supply and a field power supply interface and has a function to supply power to the I/O modules from the node interface unit via the power supply cable for base plate (A2KPB00) as well as to supply field power to the I.S. barriers by connecting the specified power
line. The tables below show the I/O modules and I.S. barriers that can be mounted on the base plate.
