n PROCEDURES FOR INSTALLING TO AND DETACHING
FROM DIN RAIL
The products can be installed on a DIN46277 rail [35mm (1.38") wide].
1) Push out all DIN rail mounting hooks (below fig.A).
2) Fit the upper edge of the DIN rail mounting groove (right fig.C) onto
the DIN rail.
3) Lock the DIN rail mounting hooks (below fig.D) while pressing the
PLC against the DIN rail.
n PROCEDURES FOR MOUNTING WITH M4 SCREWS
MOUNTING HOLE PITCHES
Refer to the External Dimensions (Section 2) for the product’s
mounting hole pitch information
n INSTALLATION
1) Make mounting holes in the mounting surface referring to the
external dimensions diagram.
2) Fit the main unit (A in the right figure) based on the holes, and
secure it with M4 screws (B in the right figure). The mounting hole
pitches and number of screws depend on the product. Refer to the
external dimensions diagram (Section 2).
3.3 TERMINAL BLOCK LAYOUT
The terminal layout in the main unit is shown below.
n EXPLANATION 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 [ + ] and [ - ] terminals.
For external wiring, make sure to read the power supply wiring
described later.
• Indication of 24VDC 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. Do not connect with [•]
terminals.
• 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.
• Indication of output terminals connected to common terminal
One common terminal covers 1, 2, 3 or 4 output points.
The output numbers (Y) connected to a common terminal are
enclosed with heavy partition lines.
For transistor output (source) type, [COMo] is [+Vo].
