Product Details

The B&B Electronics CL09 is a compact RS-232 to RS-485 serial interface converter designed to extend serial communications over longer distances and in electrically noisy industrial environments. It enables seamless integration between RS-232 host systems and RS-485 networks without the need for an external power supply.

Key Features:

  • Converts RS-232 signals to RS-485 for extended cable run capability
  • Bus-powered operation — draws power directly from the RS-232 port (no external power required)
  • Supports half-duplex RS-485 two-wire communication
  • Automatic transmit/receive direction control (no handshaking required)
  • Compact, inline DB9 form factor for easy installation
  • Wide compatibility with standard serial ports and serial-enabled devices
  • Suitable for industrial automation, PLC communication, and data acquisition applications

The CL09 is ideal for connecting RS-232-equipped computers or controllers to RS-485 multi-drop networks, making it a practical solution for factory automation, building controls, and instrumentation systems where longer cable runs or multi-device networks are required.

Ok

I mistakingly ordered two of the product. someone from customer service contacted me to verify it I actually wanted two. So we cancelled the extra order. Most companies would not go that step in customer service, much appreciated. The product arrived really fast and was exactly what I ordered and worked perfectly.

Everything was great. Shipping was fast and the price was lower than everywhere else.

Excellent and fast

Parts were easy to find and available

Thank you

Great price!

Product was easy to find and what I wanted. The whole process was seamless. I love the free shipping but also the option to pay a little and get it out faster which this time I needed.
