Power Supply
This section describes how to connect a power supply to the FC6A Series MICROSmart.
CPU Module
There are three power supply specifications for the All-in-One CPU module: the AC power type, the 24V DC power type, and the
12V DC power supply type.
The power supply specification of the Plus CPU module is the 24V DC power type only.
■
Power Supply Voltage

The power supply voltages that can be used with the All-in-One CPU module are as follows.
AC power type: 85 to 264V AC
24V DC power type: 20.4 to 28.8V DC
12V DC power type: 10.2 to 18.0V DC

The power supply voltage that can be used with the Plus CPU module is as follows.
24V DC power type: 20.4 to 28.8V DC

The power failure detection voltage varies depending on the usage conditions of the inputs and outputs, but a power failure is
normally detected when the power supply voltage is the following values.
AC power type: Less than 85V AC
24V DC power type: Less than 20.4V DC
12V DC power type: Less than 10.2V DC

For all power supply types, a momentary power interruption of 10 ms or less is not recognized as a power failure when the
power voltage is at the rated voltage.

Use a power supply of the rated value. Use of the wrong power supply may cause fire or malfunction.

Ensure that the power voltage to the FC6A Series MICROSmart does not exceed the allowable power voltage range
described in the power supply specifications. The FC6A Series MICROSmart may run and stop repeatedly within this
voltage range, particularly if the power voltage turns on or off very slowly.

Use an IEC 60127-approved fuse on the power line outside the FC6A Series MICROSmart. This is required when
equipment containing the FC6A Series MICROSmart is destined for Europe.

Do not use the FC6A Series MICROSmart outside of the power supply voltages listed above.
When an external device that carries the risk of causing a serious accident is connected to the inputs and outputs of the
FC6A Series MICROSmart, implement measures in the external circuit (such as voltage monitoring) so that the device will
function safely when there is a failure.
