6.2.2 Transistor Output Specifications (Source output type)
The table below shows the output specifications of the FX3UC-MT/DSS Main unit, FX2NC/FX2N output
extension blocks (source output type).
Outputs in the main unit are restricted by the simultaneous ON ratio.
→ For the restriction in simultaneous ON ratio, refer to Subsection 6.2.3.
*1. When the two +V terminals are connected outside the PLC, resistance load is 1.6A or less.
