Terminal Layout
The terminal layout of the main unit are explained.
4.7.1
Interpretation of terminal block layout
• Indication of power supply terminals
The AC power supply type has [L] and [N] terminals.
The DC power supply type has [
The DC power supply type has [
] and [
] terminals.
For external wiring, make sure to read the power supply wiring described later.
Refer to Chapter 8.
• Indication of 24 V DC service power supply
The AC power supply type has [0V] and [24V] terminals, whereas the DC power supply type shows [•]
since the DC power supply type does not have the service power supply.
[•] represents vacant terminals.
Do not connect with vacant terminals.
For external wiring, make sure to read the power supply wiring described later.

Refer to Chapter 8.
• Indication of input terminal
Both AC and DC power supply type have the same input terminals, however, the external input wiring
differs from each other.
For external wiring, make sure to read the input wiring described later.

Refer to Chapter 9.
• Indication of output terminals connected to common terminal
One common terminal covers 1 or 4 output points.
The output numbers (Y) connected to a common terminal are enclosed with heavy partition lines.
For transistor output (source) type, [COM] is [+V].
