Installation, Wiring, and Specifications
DL05 DC output circuits are high-performance transistor switches with low
on-resistance and fast switching times. Please note the following characteristics
which are unique to the DC output type:
S There is only one electrical common for all six outputs. All six outputs
belong to one bank.
S The output switches are current-sinking only. However, you can still use
different DC voltages from one load to another.
S The output circuit inside the PLC requires external power. The supply
(–) must be connected to a common terminal, and the supply (+)
connects the the right-most terminal on the upper connector.
In the example below, all six outputs share a common supply.

In the next example below, the outputs have “split” supplies. The first three outputs
are using a +12 VDC supply, and the last three are using a +24 VDC supply.
However, you can split the outputs among any number of supplies, as long as:
S all supply voltages are within the specified range
S all output points are wired as sinking
S all source (–) terminals are connected together
