Features:100% brand new and high qualityTheoutput of this terminal block is actually an electronic switch, double-conducting, Therefore, the terminal block can also be used in thedetecting device to control the on/off of a signal or a small load.Thisterminal block is a signal conversion isolation terminal block that canbe used for isolation of highly stable input points. The digital quantity is optically isolated.The PNP signal can also be converted to an NPN signal or an NPN signal can be converted to a PNP signal.The default input voltage of this terminal block is 10-28V. Specification:Model:DG04Input voltage: 10-28v dcOutput on-voltage: 1vMaximum output frequency :10 KHZOutput rated load current :50mA (AC/DC)Maximum output load voltage: 10-28vOutput isolation voltage :3750Vrms (min)Operating temperature :-40 ~ 85Weight: Approx.65g/2.3ozInstructions:When the input is NPN, the input common terminal COM is connected to a high level, and when the input signal is at a low level, the corresponding input indication is red lightWhen the input is PNP, the input common terminal COM is connected to the low level, and when the input signal high level is effective, the corresponding input indication is blue lightApplication examples:When PNP signal turns into NPN signal, the input common point COM and the output common point C are connected with low level 0VWhen the NPN signal turns into PNP signal, the input common point COM and the output common point C are all connected with high level 24VPackage list:1 x 4 channel level converter
