Description
About the 6GT2831-6CB00
About the 6GT2831-6CB00
The Siemens 6GT2831-6CB00 is a SIMATIC RF1000 RF1140R access control reader that connects via RJ45 with Power over Ethernet or a 24 V DC supply. It reads LF transponders (HiTag 1/2/S, EM41xx/45xx) at 125 kHz and HF transponders (ISO 14443 A/B, ISO 15693) at 13.56 MHz over TCP/IP (XML) or Modbus TCP, with an IP65 front rating after cabinet installation.
Selection Notes
The RF1140R pairs LF and HF reading with a network-native RJ45/PoE connection, so it fits a distributed door controller that polls the reader over TCP/IP or Modbus TCP without a local host PC. Choose the RF1170R instead where only HF badges are in use; choose the USB/RS232 RF1040R where the reader sits next to a PC or serial controller rather than on the network.
Applications
PoE power over RJ45 combined with LF/HF dual-band reading suits access points that still carry legacy LF badges but are being migrated to a networked door-controller architecture.
