Siemens S7-200PLC programming cable with RS232 interface, isolated, the rate is 0-115.2Kbps automatic Adaptive.
The PC/PPI+ programming cable is the transformation electric cable from RS232 to the PPI connection (RS485), and it is suitable for Simens S7-200 series PLC and the TP170 touchscreen programming, the correspondence and the monitoring. It also supports the PPI agreement and the free mouth communication protocol, and can use MODEM (modem) through the telephone line to make a long-distance correspondence. Since the cable is isolated with the electro-optical and built-in anti-static, surge and other transient over-voltage protection circuit, it solves the problem that the communication I always burned easily well. And it is especially suitable for the long-term monitoring communications which are under the industrial site with a poor environment.
Main technical parameters
Isolation voltage: 1000VDCThe maximum to 3000 VDC, orders required statementAccording to a transient voltage suppression. The RS485 port can withstand the power of up to 500 W transient over-voltage and lightning impact,the RS232 port and power circuit are equipped with surge protection to protect the circuit. The whole product can be arbitrarily charged plug.Baud rate0115.2kbps Adaptiveproducts available for sale since January 2008 The longest communication distance2 kmBaud rate:9600bps per hour,1kmBaud rate:115.2Kbps per hourWith a power indicator light and the data received and sent indicator lightTemperature:-4085products available for sale since January 2008Dimension103×50×26,The total length of cable is 5m.Signals of PC-RS232 plugs and PPI-RS485 plugs are defined as follows.
