2746980

Overview

The Phoenix Contact 2746980 is an IBS SUPI 3 OPC slave protocol chip designed for INTERBUS fieldbus systems. It operates on a 5 V DC power supply with a typical current consumption of 40 mA without analog control. The component features a TQFP 64 package with a copper block and measures 14 mm in width, height, and depth. It supports internal data lengths of 4 bytes, expandable to 64 bytes externally. The module provides user interfaces including MFP, digital I/O (2-8 IN/OUT or 16 IN/16 OUT), SPI master interface, and serial microprocessor interface. Operating ambient temperature ranges from -40 °C to 85 °C.
