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 digital input and one digital output is shown in Figure
Table 8.
