Siemens 6GT28910UE50 SIMATIC RF200/RF300/RF600 PROFINET Communication Module, 4 Reader Ports, RS422, 24V DC, DIN Rail

Four RS422 reader ports on a single PROFINET IO device—this Siemens 6GT28910UE50 communication module connects up to four SIMATIC RF200, RF300, or RF600 RFID readers to a PROFINET network at 100 Mbit/s. The integrated 2-port switch simplifies line topologies without extra hardware.

Overview

The module operates on 24 V DC (20.4–28.8 V) and draws a maximum of 0.2 A without readers. It is designed for DIN rail mounting in control cabinets (IP20) and works in ambient temperatures from -25 °C to +70 °C. Configuration and diagnostics are handled via TIA Portal or STEP 7.

What stands out

• Four reader ports with M12, 8-pin connectors for RS422 communication
• Two RJ45 PROFINET ports with integrated switch for daisy-chaining
• Supports SIMATIC RF200, RF300, and RF600 RFID systems
• LED indicators for power, PROFINET status, and reader status
