Black Box IC820A RS-232 to RS-422/485 Bidirectional Converter - External, TAA Compliant

Black Box Async RS232 to RS422/485 Interface Converter - DB9 to Terminal Block

The Black Box IC820A Universal RS-232 to RS-422/485 Bidirectional Converter offers versatile communication options for industrial and automation environments. Designed as an external transceiver, it supports both RS-485 and RS-422 protocols, enabling seamless integration in point-to-point or multipoint configurations. The device allows users to select between 2-wire half-duplex and 4-wire full-duplex operation, providing flexibility for various network topologies. Its automatic RS-485 driver control simplifies installation by eliminating the need for manual handshaking, ensuring reliable data transmission without complex programming. The converter can connect up to 32 RS-485 devices, making it ideal for large multi-drop networks with distances of up to 4,000 feet at transmission speeds up to 115 kbps. The built-in bridging switches allow quick switching between modes without external jumpers, and operating mode is easily configured with four switches on the device. It can be powered via port power or an external 120-volt AC or 12-volt DC power supply (sold separately), with no external power needed if the RS-232 handshake lines are available. The IC820A is TAA compliant, environmentally friendly, and backed by a five-year limited warranty, ensuring durability and reliable performance in demanding environments. Its compact form factor makes it suitable for various installation scenarios, providing a robust solution for extending serial communication over long distances or complex network architectures.
