DIP Switch S1 and Shunt Connector CN15
The DIP switch S1 and shunt connector CN 15 of the optional terminal board (3G3PV-PETC618120) are
described in this section.
* Note: Refer to Table 2.10 for S1 functions.
**Note: CN15 is not available at the standard terminal board.
An optional terminal board with CN15 Shunt Connector is available.
The standard setting is voltage output.
The functions of DIP switch S1 are shown in the following table.

Sinking/Sourcing Mode
The input terminal logic can be switched between sinking mode (0-V common) and sourcing mode (+24V
common) by using the terminals SN, SC and SP. An external power supply is also supported, providing more
freedom in signal input methods.
