Product Details

The B&B Electronics CL233 is a compact RS-232 to 20mA current loop converter designed to interface modern RS-232 serial equipment with legacy current loop devices. Current loop communication was widely used in industrial terminals, teletypewriters (TTY), and older serial peripherals, and the CL233 provides a reliable bridge between these two standards.

The CL233 draws its power directly from the RS-232 control lines, eliminating the need for an external power supply in most applications. Its compact, passive design makes it easy to install in-line between a host serial port and the current loop device.

Key Features:

  • Converts RS-232 signals to 20mA current loop (TTY) standard
  • Powered directly from RS-232 control lines — no external power required in most configurations
  • Compact, in-line form factor for easy installation
  • Compatible with standard DB-25 RS-232 serial interfaces
  • Suitable for connecting legacy industrial terminals, printers, and TTY devices
  • Passive design for high reliability in industrial environments

The B&B Electronics CL233 is an ideal solution for industrial facilities, data centers, and legacy system integrators who need a dependable, low-cost method to maintain RS-232 to current loop connectivity without replacing existing equipment.
