Product Description

Avyanna AT-4xT Series Serial Device Servers

The Avyanna AT-4xT Series (models AT-41T, AT-42T, and AT-44T) are rugged and versatile serial device servers designed to connect RS-232/422/485 serial devices to Ethernet networks. Supporting 1, 2, or 4 serial ports respectively, these devices offer flexible serial communication with software-selectable port types, baud rates, and standard serial settings for seamless integration.

Built for industrial environments, the series features metal enclosures with DIN-rail mounting, IP54 protection, and robust electrical isolation (up to 2.5 kV galvanic or optical isolation), ensuring reliable operation even under harsh conditions. The servers support multiple operation modes including VCOM, TCP/UDP server-client, and Telnet, providing versatile connectivity options.

Each serial port can support up to 10 simultaneous TCP connections in server mode, making these units ideal for multi-client industrial automation setups. Comprehensive LED indicators provide clear status feedback for power, communication, and network activity.
