The Black Box CL1090A-F RS-232 to Current Loop Converter provides reliable bidirectional communication between RS-232 devices and 20-mA current loop systems. Designed for versatility, this compact converter supports both active and passive operation modes, allowing seamless integration with various industrial and automation systems. In active mode, it enables an asynchronous RS-232 device to communicate with a passive 20-mA current loop device, while passive mode facilitates communication with an active device, making it adaptable to diverse setups. Constructed with optical isolators in both transmit and receive loops, the unit effectively blocks electrical interference and ground loops, ensuring signal integrity even in electrically noisy environments. This feature is essential for maintaining reliable data transmission over long distances or in industrial conditions. The converter is configured as RS-232 (DCE) but can be easily modified for DTE applications with an asynchronous modem eliminator, expanding its flexibility for different connection types. Its compact size makes it suitable for installations where space is limited, without sacrificing performance. Each converter includes separate transmit (T+ and T-) and receive (R+ and R-) loops, providing clear and isolated pathways for data signals. The Black Box CL1090A-F is manufactured in the United States and backed by a one-year limited warranty, ensuring quality and peace of mind for industrial and communication professionals. Whether used in automation, instrumentation, or remote monitoring, this signal converter offers durable and dependable performance for converting RS-232 signals to 20-mA current loops efficiently.
