For the output module (extension cable type), input/output module (extension cable type), powered input/output module and
high-speed pulse input/output module, the transistor output type is a 4-point or 8-point common output type.
■
External power supply
For driving the load, use a smoothing power supply of 5 to 30 V DC that can output a 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
The LED turns on and the output transistor turns on when photocouplers are actuated.
With CPU module, FX5-C32EYT/
 or FX5-C32ET/  , the LED target is switched with the DISP switch.
• CPU module, FX5-C32ET/  : Input (IN)/Output (OUT)
• FX5-C32EYT/  : Smaller number (F)/Larger number (L)
■
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 modules, refer to

Page 24 Output Specifications.
For output specifications of the I/O modules, refer to

Page 146 Output specifications.
For output specifications of the terminal modules, refer to

Page 162 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.
• Sink output • Source output
Connect each COM  (number) terminal to the minus side of
the load power supply.
The COM
 terminals are not connected internally.
CV  (number) terminal to the plus side of the load
power supply.
The +V
 terminals are not connected internally.
