Allen-Bradley 1783-ETAP Stratix 2000 EtherNet/IP Tap

The 1783-ETAP is a three-port discrete physical layer networking component featuring Embedded Switch Technology to integrate non-switched industrial automation devices directly into linear or Device Level Ring (DLR) network topologies. It provides raw physical layer packet steering and conversion over three copper Ethernet ports, eliminating the need for dedicated multi-port managed switches in basic control zones. The device establishes direct deterministic node aggregation over EtherNet/IP infrastructures to interconnect remote logic chassis, motor control centers, or human-machine interfaces. Powered by a regulated 24 VDC circuit, it features solid-state basic electrical insulation from network-to-power and network-to-network pathways to preserve operational data integrity in high-interference automated manufacturing environments.

Features

• Device Level Ring Integration: Enables standard point-to-point hardware terminal nodes to participate directly within single-fault tolerant DLR automation rings.
• Three-Port Copper Grid: Equipped with three independent RJ45 copper ports to route concurrent field signals.
• Rigid Signal Isolation: Implements continuous basic type insulation to guard inner control logic against communication channel spikes.
• Low Thermal Footprint: Operates efficiently with a maximum power consumption rating of 3 W, reducing internal enclosure heat generation.
• Industrial Temperature Code: Rated with North American and IEC T5 temperature codes for stable execution under restricted environmental parameters.
• Compact Open Housing: Designed with a space-saving, open-style profile to optimize spatial footprints inside main bay control panels.

Applications

• Linear and ring-configured Device Level Ring (DLR) segments in manufacturing zones.
• Inter-chassis communication bridging for distributed industrial control networks.
• Dedicated field-level extraction of diagnostic telemetry over discrete copper lines.

Installation Guidelines

• Conductor Routing Strategy: Use the designated conductor category rankings (Category 1 for power ports, Category 2 for communication ports) to isolate and plan independent internal cable tray routing paths, minimizing electromagnetic crosstalk.
• Power Terminal Torque Bounds: Fasten terminal connection screws strictly within the 0.6 to 0.8 N m window to avoid fracturing copper wire strands or stripping terminal block threads.
• Enclosure Environmental Shielding: Because this unit features an open-style enclosure rating, it must be mounted inside a secondary industrial enclosure that provides appropriate environmental protection against dust, humidity, and atmospheric contaminants.
• Power Supply Restrictions: Power lines must derive exclusively from a certified 24 VDC Class 2 or Safety Extra-Low Voltage (SELV) rated power supply to prevent overvoltage breakdown.

FAQ

Q: What is the minimum cable specification required to establish network connections on this device?

A: Communication interfaces require a minimum of 2-pair or 4-pair Category 5e cabling conforming to TIA 568-B.1, or standard Category 5 cabling conforming to ISO/IEC 24702.

Q: Can two independent wires be landed into a single terminal point on the DC power block?

A: Yes, the power terminal block can accept two solid or stranded copper wires simultaneously, provided their individual cross-sectional sizes fall between 0.33 and 1.3 mm2 (22 to 16 AWG).

Q: What isolation metrics are verified between the internal communication channels?

A: The tap is factory type-tested at 1250V AC for 60 seconds, maintaining a continuous 30V basic insulation barrier between network channels and power, as well as between separate network channels.
