NOTE
The junction terminal block CN40 (for 24 VDC) is provided.
Use them as relay terminals if necessary.
CAUTION
Operate (ON) output :
Transistor ON (sink)
Stop (OFF) output :
Transistor OFF (open)
*Upon pulse output, the
(ON),(OFF) transistors turn ON
(sink) according to the output
content. ((ON) and (OFF) refer
to the junctions in the diagram.)

• When X1, X2, Y1 and Y2 relays are used, select ones that satisfy the following specifications.
Operating coil
Rated voltage: 24 VDC (Built-in diode)
Power consumption: 0.9 W or less
(*1) Be sure to use the ones with the voltages rated above.
Exceeding the rated voltage may affect the ON/OFF of other outputs.
(*2) When using a separate power supply for this device, connect GND of the power supply to V- of CN16 of
the terminal block of this device.
(*3) Use a relay with a withstanding voltage of at least 2000 VAC between the coil and contact.
Otherwise, there is the likelihood of an electric shock or fire.
• Strip 12 1 mm (15/32 1/32 in) of the wire coating and insert firmly into the terminal.
• Make sure that the copper wiring is not short-circuiting the plates (cover, lower case) or neighboring wires.
• Perform wiring so that the terminal block is not strained.
If strained, use a wire guide or junction terminal to alleviate the stress on the terminal block.
• Do not connect the wires directly from the top of the control panel to the terminal block.
Moisture may enter this device along the wiring and cause electric shock or fire.
