■External power supply
For driving the load, use a smoothing power supply of 5 to 30 V DC that can output current two or more times the current
rating of the fuse connected to the load circuit.
■Insulation of circuit
The internal circuit of the PLC and the output transistor are insulated with a photocoupler.
The common blocks are separated from one another.
■Display of operation
Operation indicator LEDs are built into the CPU module and output modules, and turn ON when photocouplers are activated,
and the transistors are switched on.
With FX5-C32EYT/ or FX5-C32ET/, the LED target is switched with the DISP switch.
• FX5-C32EYT/: Smaller number (F)/Larger number (L)
• FX5-C32ET/: Input (IN)/Output (OUT)
■Response time
Time taken from when the photocoupler of the module is driven (or shut off) to when the transistor is turned on (or off) differs
depending on the output terminal used. For specifications of each module, refer to the following.
For output specifications of the CPU module, refer to Page 25 Output Specifications.
For output specifications of the I/O modules, refer to Page 173 Output specifications.
For output specifications of the terminal modules, refer to Page 188 Output specifications.
The transistor OFF time is longer under lighter loads. For example, under a load of 24 V DC 40 mA, the
response time is approx. 0.3 ms.
When response performance is required under light loads, provide a dummy resistor as shown below to
increase the load current.

■Output current
Maximum load differs for each module. For specifications of each module, refer to the following.
For output specifications of the CPU module, refer to Page 25 Output Specifications.
For output specifications of the I/O modules, refer to Page 173 Output specifications.
For output specifications of the terminal modules, refer to Page 188 Output specifications.
When driving a semiconductor device, carefully check the input voltage characteristics of the device.
