Wiring Terminals Section 2-2
2-2-3 Wiring
In the connection diagrams, the left side of the terminal numbers represents
the inside of the Controller and the right side represents the outside.
Power supply • With the E5CN, connect to terminals 9 and 10; with the E5CN-U, connect
to pins 10 and 11; with the E5AN and E5EN, connect pins 1 and 2. The
following table shows the specifications.
• Standard insulation is applied between the input power supply and the I/O
sections. If reinforced insulation is required, connect the input and output
terminals to a device without any exposed current-carrying parts or to a
device with standard insulation suitable for the maximum operating volt-
age of the power supply I/O section.
• In models that have an “R” at the end of the lot number, reinforced insula-
tion is applied between the input power supply, the relay outputs, and
other terminals.
Input • Make the connections as shown below, using terminals 3 to 5 for the
E5CN, pins 1 to 3 for the E5CN-U, and pins 16 and 18 for the E5AN/EN,
and matching the input types.
Control Output 1 • Outputs are sent from terminals 1 and 2 with the E5CN, from pins 4 to 6
with the E5CN-U, and from pins 3 and 4 with the E5AN/EN. The following
diagrams show the available outputs and their internal equalizing circuits.
