USB-CABLE is a programming cable that uses the USB interface to establish serial communication and convert peripheral port signals. The cable enables programming through the USB connector and a built-in serial-to-USB signal converter. Under computer control, it emulates a traditional COM port (RS-232), allowing compatibility with standard programming, communication, and monitoring software. Power is supplied from the USB port and the controller’s programming port. This USB-CABLE features optical isolation, making it suitable for use with controllers—especially in industrial environments with high electrical interference or risk of communication port damage. Comprehensive circuit protection ensures safe and reliable system operation. The cable replaces bulky first-generation adapters with a modern, compact design incorporating a high-speed communication micro-integrated chip and a 6-pin square connector on the PLC side. It offers improved portability, stability, and performance. Compatible with Siemens Series PLCs. Length: 3 meters.
