*1 OFF→ON return time is 125 ms.
*2 Note the derating illustrated in the graph to the right when using PNP output.
*3 This includes situations in which the SL-C Series is off and in which the power supply line is disconnected.
*4 The wiring resistance between the OSSD output and the connected equipment (excluding the wiring resistance of the optional dedicated cable) must be 2.5 Ω or less to ensure that the SL-C Series operate correctly. If using the NPN output
