2 SYSTEM CONFIGURATION
No. Name Application
7) Power input terminals
• 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)
8)
+24V, 24G terminals
(Q62P only)
Used to supply 24VDC power to inside the output module. (using external wiring)
9) Terminal screw M3.5 7 screw
10) Terminal cover Protective cover of the terminal block
11) Module fixing screw hole
Used to fix the module to the base unit.
M3
12 screw (user-prepared) (Tightening torque: 0.36 to 0.48
N•m)
12) Module mounting lever Used to load the module into the base unit.
(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).
POINTS
(1) The Q61P-A1 is dedicated for inputting a voltage of 100VAC.
Do not input a voltage of 200VAC into it or trouble may occur on the Q61P-A1.
Power
module type
Supply power voltage
100VAC 200VAC
Q61P-A1 Operates normally.
Power supply module causes
trouble.
Q61P-A2
Power supply module does not
cause trouble.
CPU module cannot be operated.
Operates normally.
(2) The Q63P is dedicated for inputting a voltage of 24VDC.
Do not input a voltage of except 24VDC into it or trouble may occur on the Q63P.
(3) Q64P automatically switches the input range 100/200VAC.
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.
(4) Ensure that the earth terminals LG and FG are grounded.
(Ground resistance : 100
or less)
Since the LG terminal has a half of the input voltage, touching this terminal may
result in an electric shock.
(5) When the Q61P-A1, Q61P-A2, Q61P, Q61P-D, Q62P, Q63P, Q64P or Q64PN is
loaded on the extension base unit, a system error cannot be detected by the
ERR.
terminal. (The
ERR.
terminal is always OFF.)
(6) Cables for the
ERR.
contact and the
LIFE OUT
contact must be 30m or more and
installed in the control panel.
