2.5 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 15 and described in Table 7.

The I/O user interface is designed for binary input processing and binary output control.
For detailed electrical parameters see Chapter 4.6. The functional scheme of connection for
the binary input and binary output is in Figure 16.
