2746977

Overview

Phoenix Contact part number 2746977 is an IBS SUPI 3 LS slave protocol chip designed for INTERBUS communication. The component measures 12 mm in width, depth, and length, with a weight of 3.66 g excluding packaging. It operates on a 5 V DC power supply (±10%) and typically consumes 40 mA of current. The device features a TQFP 44 package type and supports a 32-bit internal data length with external expansion capabilities. Operating ambient temperature ranges from -40 °C to 85 °C at up to 75% humidity, while storage and transport conditions require temperatures between 5 °C and 30 °C.

Feature Summary

• Designed specifically as a slave protocol chip for INTERBUS networks
• Supports 32-bit internal data processing with provisions for external expansion
• Utilizes a compact TQFP 44 package format

Applications

• INTERBUS network slave nodes
• Industrial automation control systems
