 GENERAL
This GS describes the connection between the I/O Modules for FIO and field devices.
 SIGNAL CONNECTIONS
 Variation of Signal Connections
The I/O Modules can be connected to field devices by terminal connection or with a terminal block via a KS cable
interface adapter. A customer-furnished MIL cable can also be used to connect to the I/O Module.
The following explains the terminal blocks as well as the signal wiring that can be paired with the I/O Modules.
Configuration of I/O Module Connection
A pressure clamp terminal block is provided for the terminal connection with field devices. To expand terminals via
terminal boards, connect a KS cable adapter to an I/O Module. When using a customer-furnished MIL connector
cable, can directly connect to an I/O Module.
A dedicated terminal block is provided for a dual-redundant configuration.
