The following explains the terminal blocks as well as the signal wiring that can be paired with the I/O Modules.
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
