1. ELC-PV/ELC2-PV series controllers have
either relay or transistor outputs. See
“Function Specifications” for their
specifications.
2. Please note the connection of shared
terminals when wiring output terminals.
3. Output terminals, Y0, Y1, and Y2, of relay
models use C0 common port; Y3, Y4, and
Y5 use C1 common port; Y6, Y7, and Y10
use C2 common port; Y11, Y12, and Y13
use C3 common port, as shown below.

When output points are enabled, their
corresponding indicators on the front panel
will be on.

5. Isolation circuit: The optical coupler is used
to isolate signals between the circuit inside
ELC and input modules.

6. The output terminals Y0~Y7 on the transistor
(PNP) model are connected to the common
terminals UP0 and ZP0. Y10~Y13 are
connected to the common terminals UP1
and ZP1, as shown below.
