Why Choose the TE Connectivity BFHE-10/20-16-TFL-S Interfast Interface?

The TE Connectivity BFHE-10/20-16-TFL-S, manufacturer part number 1SNA020873R2600, is an industrial 16-channel interruptible three-wire interface with fuse protection and blown-fuse LED indication. Part of the established Entrelec Interfast PCB range, it is designed to provide an organised connection between a 20-pole HE10 multipole connector and individual control circuits within industrial automation panels.

Each channel incorporates an interruptible connection with fuse protection, while a blown-fuse LED on each positive common provides convenient visual fault indication. This combination allows circuits to be protected, isolated and diagnosed from the interface, making the BFHE-10/20-16-TFL-S particularly useful in PLC and automation installations where rapid fault identification and straightforward maintenance are important.

The BFHE-10/20-16-TFL-S has an IEC rated voltage of 30 V and dimensions of approximately 104 × 64.5 mm. Its integrated HE10/20 connector consolidates multiple signals into a single multipole connection, helping reduce point-to-point wiring and providing a practical high-density interface for machinery, process control and industrial automation systems.

Fused Signal Interfacing with Clear Fault Indication

Fused interface modules provide a convenient way to combine signal distribution, circuit protection and diagnostics within one control-panel assembly. When a fault causes a fuse to operate, visual indication can help maintenance personnel identify the affected circuit without tracing numerous individual conductors throughout the cabinet.

The BFHE-10/20-16-TFL-S combines this functionality with an interruptible three-wire architecture and HE10/20 multipole connectivity. The result is a practical interface for installations requiring multiple protected control circuits, convenient isolation and straightforward troubleshooting while reducing the amount of conventional point-to-point wiring required.

Typical Applications

• PLC input and output interface wiring.
• Fused industrial control and signal circuits.
• Industrial control panels and electrical cabinets.
• Machine control and factory automation systems.
• Process control and production equipment.
• Signal isolation, testing and fault-diagnostic applications.
