Specifications Power supply module specifications
12 – 60
Power supplies are integrated into Q00JCPU and Q00UJCPU

When power is switched on again immediately (within 5 seconds) after power-off, an inrush current of more than
the specified value (2 ms or less) may flow.
Reapply power 5 or more seconds after power-off.
When selecting a fuse and breaker in the external circuit, take account of the blowout, detection characteristics
etc.

Overcurrent protection
The overcurrent protection device shuts off the 5 V, 24 VDC circuit and stops the system if the current flowing in
the circuit exceeds the specified value.
The LED of the power supply module turns off or turns on in dim green when voltage is lowered. If this device is
activated, switch the input power supply off and eliminate the cause such as insufficient current capacity or short.
Then, a few minutes later, switch it on to restart the system.

Overvoltage protection
The overvoltage protection device shuts off the 5 VDC circuit and stops the system if a voltage of 5.5 VDC is
applied to the circuit.
When this device is activated, the power supply module LED turns off.
If this happens, switch the input power off, then a few minutes later on. This causes the initial start for the system
to take place. The power supply module must be changed if the system is not booted and the LED remains off.

If the momentary power failure time is within 20 ms, the system detects an AC down and suspends the operation
processing. However, the system continues operations after the power comes back.
If the momentary power failure time exceeds 20 ms, the system either continues or initially starts operations
depending on the power supply load. In case that the operation processing is continued, the system operates the
same as when the momentary power failure time is within 20 ms.
Supplying the same amount of AC to both the power supply module and the input module (such as QX10) can
prevent the sensor connected to the input module from being switched to the OFF status when the power supply
turns off.
Note, however, that if only the input module (such as QX10) is connected on the AC line, which is connected to
the power supply, an AC down detection in the power supply module may be delayed due to the internal capacitor
of the input module. To avoid this, connect a load of approx. 30 mA per input module on the AC line.
