Termination module
1. Overview
is product is an I/O module that uses external signals to perform
operations within the composition units and to output data. It is
used in combination with a main module and counter modules.
is module has eight inputs and eight outputs, and the function of
each pin is set by the display unit.
During operation, also refer to the display unit and main module
Instruction Manuals.
