MELSEC-Q
5 POWER SUPPLY MODULE
No. Name Application
1) POWER LED 5VDC power indicator LED
2) ERR
terminals
1) Turned ON when the whole system operates normally.
2) Turned OFF (opened) when a stop error occurs in the CPU module.
3) In a multiple CPU system configuration, turned OFF when a stop error occurs in
any of the CPU modules.
Normally off when loaded in an extension base unit.
3) FG terminal Ground terminal connected to the shield pattern of the printed circuit board.
4) LG terminal
Grounding for the power supply filter. The potential of Q61P-A1, Q61P-A2, Q62P,
Q64P and Q61SP terminal is 1/2 of the input voltage
5) +24V, 24G terminals Used to supply 24VDC power to inside the output module (using external wiring).
6) Terminal screw M3.5 × 7 screw
7) Terminal cover Protective cover of the terminal block
8) Module fixing screw hole
Used to fix the module to the base unit. M3 × 12 screw (user-prepared)
(Tightening torque : 36 to 48N•cm)
9) Module loading lever Used to load the module into the base unit.
10) Power input terminals Used to connect a 100VAC power supply.
11) Power input terminals Used to connect a 200VAC power supply.
12) Power input terminals Used to connect a 100VAC to 200VAC power supply.
13) Power input terminals Used to connect a 24VAC power supply.
14) Power input terminals Used to connect a 100VAC/200VAC power supply.
POINTS
(1) The Q61P-A1 is dedicated for inputting a voltage of 100 VAC.
Do not input a voltage of 200 VAC into it or trouble may occur on the Q61P-A1.
Supply power voltage Power
module type
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) 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 work normally if the above intermediate voltage is
applied.
(3) Ensure that the earth terminals LG and FG are grounded.
