Product Details

The B&B Electronics CL41 is a passive current loop converter designed to interface current loop devices with standard RS-232 serial ports. It enables reliable communication between legacy current loop equipment and modern RS-232-compatible computers or serial interfaces without requiring an external power supply.

Key Features:

  • Converts 20mA current loop signals to RS-232 logic levels
  • Passive design — draws power directly from the RS-232 port, no external power needed
  • Compact, inline form factor for easy installation
  • Supports full-duplex current loop communication
  • Compatible with a wide range of serial devices including terminals, printers, and industrial controllers
  • Rugged construction suited for industrial environments

The CL41 is an ideal solution for connecting older current loop peripherals to PC serial ports, making it a practical tool for maintaining and extending the life of legacy industrial and commercial equipment.

The website was easy to navigate. I found the product easy peasy. Placed order and my order was delivered within days not weeks. I would order again from them if I ever need shocks again.

Quick and easy ordering, check out and fast shipping.

Exactly what I ordered.

Great! Friendly whe buying and fast shipping, coming back for more!!!

Ordering was easy

The only thing that didn't go very well was the time it took to receive the 2nd part of my order. I paid extra for 2 day shipping. It took closer to 6 days to receive my CDI switch box.

Easy no hassle purchasing fast shipping

Happy, just didn't get confirmation email after order was placed.

no thankyou,
