USB-CABLE is a programming cable that uses the USB interface to achieve serial connection and peripheral port signal conversion. Cable programming is provided through the USB interface connector and serial peripherals signal converter programming, under the control of computer operation, simulating the computer's USB interface to traditional serial (commonly known as COM port), thus using the current programming software, communication software, and monitoring software. The working power of the cable comes from USB port and programming port of LOGO controller. USB-LOGO CABLE is photoelectric isolated and can be applied to LOGO Controller, especially the industrial fields with greater interference and easily damaged communication ports. Various protection measures in the circuit allow for the safe operation of the system. USB-LOGO cable removes the 1st generation heavy adapter appearance and applies a new design with a high-speed communication micro-integrated chip built-in 6-pin square shape port side. It is more portable and functions more stable and powerful. Purpose: Suitable for LOGO Series PLC programming cable Length: 3 meters Please check the interface before placing your order: PC-CABLE: PC side is 9-pin female plug RS232 port, PLC side 6-pin square shape USB-CABLE: USB port connects PC, PLC side 6-pin square shape Color: black Material: PVC + copper wire Package Contents: 1 x PLC programming cable Only the above package content, other products are not included.
