The functions of DIP switch S1 are shown in the following table.
Name
S1-1
S1-2
Sinking/Sourcing Mode
The input terminal logic can be switched between sinking mode (0-V common) and sourcing mode (+24-V
common) by using the terminals SN, SC, and SP. An external 24-V power supply is also supported, providing
more freedom in signal input methods.

*Note: Refer to Table 2.12 for S1 functions and
to Table 2.13 for Sinking/Sourcing Mode
and Input Signals.
**Note:CN15 is not available at the standard ter-
minal board. An optional terminal board
with CN15 Shunt Connector is available.
The standard setting is voltage output.
OFF: No terminating resistance
ON: Terminating resistance of 110 Ω
OFF: 0 to 10 V (internal resistance: 20 kΩ)
ON: 4 to 20 mA (internal resistance: 250 Ω)
