Input Point Wiring
There are two types of DC inputs, SINK and SOURCE. (See the example below. For
detailed point configuration, please refer to the specification of each model.)

Output Point Wiring
1. ELC2-PA series controllers have either relay or transistor (NPN/PNP) outputs.
Please note the connection of shared terminals when wiring output terminals.
2. Output terminals, Y0, Y1, and Y2, of relay models use C0 common port; Y3, Y4, and
Y5 use C1 common port; as shown in the following figure. When output points are
enabled, their corresponding indicators on the front panel will be on.
3. Output terminals, Y0 ~Y5 of transistor (NPN/PNP) models use UP, ZP common port;
as shown in the following figures.
4. Isolation circuit: The optical coupler is used to isolate signals between the circuit
inside PLC and input modules.
