Introduction: Cp5512 is the isolated profibus/mpi/ppi/fwl communication card specially for laptop, use icoupler isolators eliminate optocoupler limitations instead of photoelectric isolation, with small dimension, wide temperature range, and have anti-lightning and surging protective circuit and overcurrent protection with restoration function on the rs485 interface, all use industrial ic in order to apply to wider temperature range, is used to achieve profibus/mpi/ppi/fwl communication connection between laptop and simatic. Cp5512 insert laptop pcmcia slot from outside. Its function and features is the same as siemens original cp5512(siemens part nr 6gk1551-2aa00 ), and have the following new characters. Technical specification: Transmission rate: 9.6kbps12mbps, the corresponding largest communication distance accord with profibus standard. Interface:connect profibus/mpi/ppi, isolated 9 pin sub-d connector. Isolated voltage:1000vdc Interface protection:have anti-lightning and surging protection(ipp=100a 10/700us, 4kv) on the rs485 interface.Itu-tk20/21, vde 0433 standard. 15kv esd protection. Overcurrent protection with restoration function£ºrs485 port can withstand up to 60v voltage caused by continuous over-current. Support hardware of cp5512: different from pc adapter and pc adapter usb, cp5512 supports much more hardwares, such as siemens s7-200/300/400plc, ppi/mpi/profibus interface of touch panel, em277, et20 and other hardwares with profibus/mpi/ppi/fwl interface. It need profibus cable or mpi cable(siemens part nr 6es7 901-0bf00-0aa0) when cp5512 communicates with fieldbus devices.
