Product Details

The B&B Electronics CL217 is a passive RS-232 to 20mA current loop converter designed for connecting RS-232 serial devices to current loop interfaces. Current loop is a legacy serial communication standard commonly found in older industrial equipment, terminals, and printers, and the CL217 provides a reliable bridge between modern RS-232 ports and these systems.

Key Features:

  • Converts RS-232 signals to 20mA current loop (active or passive configurations)
  • Supports full-duplex serial communication
  • Compact, inline form factor for easy installation
  • No external power required — draws power from the RS-232 host port
  • Compatible with a wide range of legacy industrial terminals, printers, and instrumentation
  • Manufactured by B&B Electronics (Advantech B+B SmartWorx), a trusted name in serial communications

The CL217 is ideal for industrial automation, data acquisition, and legacy system integration applications where RS-232 to current loop signal conversion is required. Its passive, self-powered design simplifies installation with no additional power supply needed.

Great!

Haven't found the time to work on my SL.

Shipping took longer than expected as I paid for expedited shipping. I reached out to ask why it wasn't sent two day and got no reply. The customer service could really use improvement and this is reflected in multiple reviews. However, the products arrived safely and as described. I'm very satisfied with the pricing as well. At the end of the day, that's the most important thing.

The whole experience was so much fun

It was a good product my first one blew up so I needed another

Fast delivery. Astonishingly cheaper than other sources. A+++

Shipping too expensive!

Best price I found on this intake online. Easy check out process!
