5.2.1
Direct Connection Using Pressure Clamp Terminals
The interface part of an I/O module basically consists of a connector (male). Connect the
pressure clamp terminal block to the front section.
Pressure clamp terminals are available for single and dual-redundant operation.

External View of Terminal Blocks
One I/O module can be connected with one single-type pressure clamp terminal block.
Two adjacent I/O modules can be connected with one dual-type terminal block for dual-redun-
dant configuration. The width of the dual-type terminal block is two times of a single-type ter-
minal block.
The two flat cables at the back of the dual-type terminal block are connected to two I/O mod-
ules.
