Product Details

The B&B Electronics CL234 is a compact RS-232 to 20mA current loop signal converter designed for connecting modern RS-232 serial devices to legacy current loop equipment. Current loop interfaces were widely used in industrial and teletype applications before RS-232 became standard, and the CL234 bridges that gap — allowing older equipment to communicate with contemporary serial hardware without protocol modification.

Key Features:

  • Converts RS-232 signals to 20mA current loop and vice versa
  • Supports full-duplex serial communication
  • Compact, DIN-rail or panel-mountable form factor suitable for industrial environments
  • Passive and active current loop modes supported
  • No external power required in passive mode (loop-powered operation)
  • Wide operating temperature range for industrial deployments
  • LED indicators for transmit/receive activity

The CL234 is ideal for manufacturing facilities, process control environments, and any application requiring reliable integration between RS-232 serial ports and 20mA current loop peripherals such as printers, PLCs, and legacy terminals.

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.
