6.2 Transistor Output
6.2.3 Output Derating Curve
The derating curve below shows the simultaneous ON ratio of available PLC inputs with respect to the
ambient temperature. Use the PLC within the simultaneous input ON ratio range shown in the figure.
1. In case of the FX3UC-MT/D, DSS
2. In case of the FX
3UC-32MT-LT
6.2.4 Handling of transistor output
1. Output terminals
4, 8 or 16 transistor output points are covered by one common terminal.
Sink output
Two COM terminals connected each other inside the PLC
are provided for sink outputs in the FX
3UC main unit,
transistor output type extension blocks for FX
2NC and
FX
2N-16EYT-C.
For external wiring, connect two COM terminals outside
the PLC so that the load applied on each COM terminal
becomes smaller.
