1sna631027r1600 – bom-16-bl

Why Choose the TE Connectivity BOM-16-BL PLC Connecting Interface?

The TE Connectivity BOM-16-BL, part number 1SNA631027R1600, is a 16-channel two-wire PLC connecting interface with integrated LED indication designed to simplify connections between programmable controllers and field devices. Part of the ENTRELEC Interfast MS system, it combines a 20-pole Omniconnect plug with screw-clamp field terminals to provide an organised and efficient interface for industrial automation wiring.

Unlike the non-illuminated BOM-16-B version, the BOM-16-BL incorporates LED status indication for its 16 channels. These indicators provide convenient visual feedback on signal status, assisting technicians during commissioning, operation and fault diagnosis. The interface is particularly suitable for connecting two-wire sensors or actuators to PLC systems while reducing conventional point-to-point panel wiring.

The LED-equipped BOM-16-BL is designed for a maximum voltage of 30 V DC, with a maximum current of 2 A per point and 5 A in the common conductors. Each LED draws approximately 5 mA, while the field terminals accommodate conductors up to 2.5 mm².

Key Advantages

• Compact 16-channel two-wire PLC connecting interface.
• Integrated LED indication provides clear visual channel-status monitoring.
• 20-pole Omniconnect plug simplifies the controller-side connection.
• Screw-clamp field terminals provide secure and serviceable conductor connections.
• Supports up to 2 A per point and 5 A through the common conductors.
• Reduces individual point-to-point wiring between PLCs and field devices.
• DIN rail mounting enables straightforward integration into industrial control cabinets.

Efficient PLC Wiring with Visual Status Indication

PLC interface modules provide an organised connection point between controller I/O and sensors, actuators or other field equipment. The BOM-16-BL groups 16 two-wire channels into one DIN rail-mounted module, replacing numerous individual controller-side connections with a single 20-pole Omniconnect interface.

Integrated LEDs add immediate visual signal monitoring, making it easier to identify active channels and diagnose wiring or equipment conditions during commissioning and maintenance. This combination of consolidated wiring, screw-clamp field connections and visual indication makes the BOM-16-BL particularly useful in densely populated industrial automation cabinets.

Typical Applications

• PLC input and output interface wiring.
• Two-wire sensor and actuator connections.
• Industrial control and automation cabinets.
• Factory automation systems.
• Machine control and production equipment.
• Process control installations.
• Applications requiring visual LED channel-status indication.
