For the output module (extension connector type) and input/output module (extension connector type), the transistor output
type is an 8-point common output type.
• Sink output
The COM (number) terminals that are connected each other inside
the PLC are prepared. For external wiring, connect the COM
(number) terminals outside the PLC to reduce the load per one
COM terminal.

■External power supply
For driving the load, use a smoothing power supply of 5-30 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/D(SS) or FX5-C32ET/D(SS), the LED target is switched with the DISP switch.
• FX5-C32EYT/D(SS): Smaller number (F)/Larger number (L)
• FX5-C32ET/D(SS): 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 31 Output Specifications.
For output specifications of the I/O modules, refer to Page 152 Output specifications.
For output specifications of the terminal modules, refer to Page 170 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.

The +V (number) terminals that are connected each other inside the
PLC are prepared. For external wiring, connect the +V (number)
terminals outside the PLC to reduce the load per one +V terminal.
