ON (green): Normal (5VDC output, momentary power failure within 20ms)
OFF : • AC power supply is ON, however, the power supply module is out of order.
(5VDC error, internal circuit failure, blown fuse)
• Over current protection or over voltage protection operated.
• AC power supply is not ON
• Power failure (including an momentary power failure of more than 20ms)
ON (green): Normal (5VDC output, momentary power failure within 10ms)
OFF : • DC power supply is ON, however, the power supply module is out of order.
(5VDC error, internal circuit failure, blown fuse)
• Over current protection or over voltage protection operated.
• DC power supply is not ON
• Power failure (including an momentary power failure of more than 10ms)
• Turned ON when the whole system operates normally.
• This terminal turns OFF (opens) when the AC power is not input, a stop error (including a
reset) occurs in the CPU module, or the fuse is blown.
• In a Multiple CPU system configuration, turned OFF (opens) when a stop error occurs in
any of the CPU modules.
Normally OFF when loaded in an extension base unit.
• Turned ON when the whole system operates normally.
• This terminal turns OFF (opens) when the DC power is not input, a stop error (including a
reset) occurs in the CPU module, or the fuse is blown.
• In a Multiple CPU system configuration, turned OFF (opens) when a stop error occurs in
any of the CPU modules.
Normally OFF when loaded in an extension base unit.
Ground terminal connected to the shield pattern of the printed circuit board.
Grounding for the power supply filter. The potential of Q61P-A1, Q61P-A2, Q61P, Q62P
and Q64P terminal is 1/2 of the input voltage.
• Power input terminals connected to a power supply of 100VAC or 200VAC.
(Q61P-A1, Q61P-A2, Q64P)
• Power input terminals connected to a power supply of 100VAC to 200VAC.
(Q61P, Q62P)
• Power input terminals connected to a power supply of 24VDC.
(Q63P)
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.
