I/O Port Interfaces
The maximum length of wires connected to the I/O ports is 3 meters to meet the EMC
immunity conditions.
The pins of I/O interface are physically connected to the 6-pin terminal block panel socket
located on the left panel. The pinout of one binary input and one binary output is shown in
Figure
and described in Table
