1. The QS061P-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 
QS061P-A1.

2. Individually ground the LG and FG terminals with a ground resistance of 100

 

or less.

3. ERR. terminal cannot be used as a safety output.

Connect the cable for ERR. contact of 30m or less in length in a control panel.

1)

"POWER" LED

On (green) : Normal (5VDC output, instantaneous power failure within 20ms)
Off

: • AC power supply is ON, however, the power supply module is out of 

order.
(5VDC error, overload, internal circuit failure, fuse blown)

• AC power supply is not ON.
• Power failure (including an instantaneous power failure of 20ms or 

more)

2)

ERR. terminal

• Turned ON when the whole system operates normally.
• 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.

3)

FG terminal

Ground terminal connected to the shielding pattern of the printed-circuit board.

4)

LG terminal

Grounding for the power filter. The potential of the QS061P-A1 and QS061P-A2 ter-
minals are one-half of the input voltage.

5)

Terminal screw

M3.5 screw

6)

Terminal cover

Protective cover of the terminal block

7)

Module fixing screw

Used to fix the module to the base unit. 
M3 screw (Tightening torque range : 0.36 to 0.48N•m)

8)

Module loading lever

Used to load the module to the base unit.

9)

Power input terminal

Power input terminal for the QS061P-A1 and connected to a 100VAC power supply.

10)

Power input terminal

Power input terminal for the QS061P-A2 and connected to a 200VAC power supply.

QS061P-A1

Operates normally.

Power supply module causes 

trouble.

QS061P-A2

Power supply module does not 
cause trouble.
CPU module cannot be 
operated.

Operates normally.
