[Function] The output of this terminal block is actually an electronic switch, double-conducting, Therefore, the terminal block can also be used in the detecting device to control the on/off of a signal or a small load. [Convertible] The PNP signal can also be converted to an NPN signal or an NPN signal can be converted to a PNP signal. [High Performance] This terminal block is a signal conversion isolation terminal block that can be used for isolation of highly stable input points. The digital quantity is optically isolated. [Input voltage] The default input voltage of this terminal block is 10-28V., Manufacturer: Akfldms
