Source output
Two +V terminals (connected to each other inside the
PLC) are provided for sink outputs in the FX
transistor output type extension blocks (source type) for the
FX
2NC.
For external wiring, connect two +V
PLC so that the load applied on each +V
becomes smaller.
2. External power supply
For driving the load, use a smoothing power supply of 5 to 30V DC that can output current two or more times
the rated current of the fuse connected to the load circuit.
3. 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.
4. Display of operation
Operation indicator LEDs are built into the main unit and output extension blocks, and turn ON when
photocouplers are actuated. The FX
can be monitored with the display module.
5. Response time
The time from when the PLC drives (or shuts down) the photocoupler until the transistor is turned on (or off) is
shown in the following table.

*1. The transistor OFF time is longer under lighter loads. For example, under a load of 24V DC 40mA, the
response time is approx. 0.3ms. When response performance is required under light loads, provide a
dummy resistor as shown below to increase the load current.
