(Note-1): When using the Q61P-D in a system configured with an extension base unit, the POWER LED of the Q61P-D on
the extension base unit may turn a dull red color when the power is turned OFF. Note that this does not indicate
an error.
(Note-2): Flicker-OFF indicates that the output signal of the terminal turns OFF and ON three times at intervals of one
second before turning OFF (opens).
(1) The Q61P-A1 is dedicated for inputting a voltage of 100VAC.
(2) The Q63P is dedicated for inputting a voltage of 24VDC.
(3) Q64P automatically switches the input range 100/200VAC.
(4) Ensure that the earth terminals LG and FG are grounded.
(5) When the Q61P-A1, Q61P-A2, Q61P, Q61P-D, Q62P, Q63P, Q64P or Q64PN is

• Power input terminals connected to a power supply of 100VAC. (Q61P-A1)
• Power input terminals connected to a power supply of 200VAC. (Q61P-A2)
• Power input terminals connected to a power supply of 100VAC to 200VAC.
(Q61P, Q61P-D, Q62P, Q64PN)
• Power input terminals connected to a power supply of 24VDC. (Q63P)
• Power input terminals connected to a power supply of 100VAC/200VAC. (Q64P)
Used to supply 24VDC power to inside the output module. (using external wiring)
M3.5 7 screw
Protective cover of the terminal block
Used to fix the module to the base unit.
M3 12 screw (user-prepared) (Tightening torque: 0.36 to 0.48 N•m)
Used to load the module into the base unit.
POINTS
Do not input a voltage of 200VAC into it or trouble may occur on the Q61P-A1.

Q61P-A2 cause trouble.
CPU module cannot be operated.
Do not input a voltage of except 24VDC into it or trouble may occur on the Q63P.
Therefore, it is not compatible with the intermediate voltage (133 to 169VAC).
The CPU module may not operate normally if the above intermediate voltage is
applied.

Since the LG terminal has a half of the input voltage, touching this terminal may
result in an electric shock.
