Either PNP or NPN sensors can be connected directly.5.Do not input a negative (-) signal to the analog inputs (I4, I5). Theinternal elements may be damaged if a negative signal is input.Wiring Output Circuits(1) Relay Output TypeAll 4 outputs in the relay output circuits have independent contacts.There are no particular restrictions on polarity.LoadLoadLoadLoadLoadExpansion I/O UnitLoadLoadLoadCPU Unit250 VAC, 8 A (cosø = 1)24 VDC, 5 A35WiringSection 2-2(2) Transistor Output TypeAll 4 outputs in the transistor output circuits have independent contacts.
Their terminals have polarity, but no problem will result fromreversing the connection positions of the power supply and load.24 VDC, 0.5 A36LoadLoadLoadLoadLoadExpansion I/O UnitLoadLoadLoadLoadCPU UnitSECTION 3Programming and Operating MethodsThis section explains how to create and edit ladder programs and how to use the timers, counters,comparators, display function and buttons switches.3-13-23-3Selecting Display Language . . . .
