Black Box CL1090A-F RS-232 to Current Loop Converter for Industrial Signal Transmission

The Black Box CL1090A-F RS-232 to Current Loop Converter provides reliable bidirectional communication between RS-232 devices and 20-mA current loops in industrial environments. Designed for versatility, this converter supports both active and passive operation modes, allowing seamless integration with various systems. In active mode, it enables an asynchronous RS-232 device to communicate with a passive 20-mA current loop device, while in passive mode, it facilitates communication with an active current loop device, enhancing flexibility for different application requirements. Its compact size makes it suitable for space-constrained installations, and the optical isolation in both transmit and receive loops effectively prevents electrical interference and ground loop issues, ensuring signal integrity and device protection. This converter features separate transmit (T+ and T-) and receive (R+ and R-) loops, providing robust and noise-free data transfer. Configurable as RS-232 DCE, it can also be adapted for DTE use with an optional asynchronous modem eliminator, broadening its compatibility. Built in the United States by Black Box Corporation, the CL1090A-F is backed by a one-year limited warranty, offering peace of mind for critical industrial applications. Whether used in automation, instrumentation, or industrial control systems, this signal converter ensures stable and accurate data communication across different signal standards and environments.
