2746391

Overview

The Phoenix Contact 2746391 is a master protocol chip designed for INTERBUS fieldbus systems, housed in an SOP 16 package. It operates on a 5 V DC supply with typical current consumption of 10 mA and supports an ambient temperature range from -40 °C to 85 °C. The component facilitates communication via a V.24 user interface configured with one start bit, two stop bits, eight data bits, and even parity. It manages up to 4096 bytes of process data and supports connections to 512 devices within the network.

Feature Summary

• Integrated INTERBUS master protocol functionality
• Supports extensive device networking capabilities
• Compatible with standard UART serial communication interfaces

Applications

• INTERBUS master controller implementation
• Industrial automation system integration
