The Honeywell TK-FTEB01 (51309512-175) is a Fault Tolerant Ethernet (FTE) Bridge Module engineered for the Honeywell Experion PKS and Experion LS distributed control systems. This module serves as a critical communication interface, enabling high-speed, 100 Mbps Ethernet (IEEE 802.3) connectivity between Experion Servers, C200 controllers, and Fieldbus Interface Module (FIM) chassis. The 'TK-' prefix indicates that this unit features conformal coating, providing enhanced protection against corrosive industrial environments (G2/G3 rated per ANSI/ISA-S71.04-1985).
| Product Model | TK-FTEB01 |
| Part Number | 51309512-175 |
| Communication Speed | 100 Mbps (IEEE 802.3) |
| Input Voltage | 18-30 VDC |

The TK-FTEB01 acts as an FTE communications bridge, routing data between the Honeywell Experion controller network and Series-A I/O chassis modules to ensure redundant, high-availability process communication.
The module uses a device index system. By assigning an odd index to the primary and an even index to the secondary, the Honeywell server automatically manages IP addressing and path failover, eliminating the need for manual BOOTP or IP table configuration.
The module features a 4-character display. During normal operation, it shows 'OK'. If an FTE link fails, it will display specific error codes (e.g., '18 FAIL') to identify which network path (FTE A or FTE B) is experiencing a fault.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
