Configured for unmanaged Ethernet switching tasks in EtherNet/IP networks, the Allen-Bradley 1783-US03T01F (1783-US03T01F Stratix Managed Switches) provides direct physical/electrical execution.

Configuration and Catalog Structure

The 1783-US03T01F belongs to the Stratix 2000 product line. The hardware architecture incorporates three 10/100 Mbps copper ports supporting full or half duplex transmission and one 100BASE-FX multimode fiber port utilizing an LC connector interface. Power input is designed for 20 VAC or 24 VDC systems.

Hardware Specifications

Industrial Automation Control Integration

Operating within Allen-Bradley control architectures, this unmanaged switch executes deterministic Ethernet/IP network transmission across distributed nodes. The unit maintains stable backplane bus communication velocity, supporting strict packet transfer intervals for connected I/O and controller hardware. The device requires no firmware configuration, ensuring transparent Layer 2 frame forwarding across plant-floor topologies without introducing software-induced latency or routing overhead.

Field Installation Guidelines

• DIN-Rail Mounting: Secure the switch housing directly onto standard industrial DIN rails, ensuring positive locking engagement of the rear mechanical latch.
• Power Cabling: Terminate the incoming 20 VAC or 24 VDC supply lines to the removable terminal block, maintaining correct polarity and torque specifications.
• Shielding and Grounding: Bond the functional ground terminal to the local control cabinet ground bus using low-impedance copper wire to mitigate electromagnetic interference.
• Fiber Optic Handling: Maintain minimum bend radius limits for the 62.5/125 multimode fiber cables and protect LC connectors from particulate contamination prior to insertion.

Frequently Asked Questions

• Does this switch require software configuration prior to network deployment?
• No configuration is required. The unit functions strictly as an unmanaged layer-2 device and operates immediately upon power application.
• What is the maximum data transmission rate supported by the copper ports?
• The copper ports support 10/100 Mbps data rates in both full and half duplex operational modes.
• Can the multimode fiber port communicate with single-mode fiber infrastructure?
• No. The fiber transceiver is designed exclusively for 62.5/125 multimode fiber optics utilizing an LC connector format.
• How is electrical isolation maintained within the unit?
• The internal circuitry maintains a rated isolation voltage threshold of 30 V to isolate power input from communication channels.
• What is the specified inrush current during initial power-up?
• The unit draws an inrush current of 2.2 A when power is initially applied to the terminal block.
• Is hot-swapping supported for the power supply terminals?
• Power connections should be de-energized before removing the terminal block to prevent electrical arcing and terminal degradation.
• What standard regulatory marks are stamped on the device housing?
• The hardware complies with C/Us, CE, UL, and C-Tick industrial regulatory standards.
• How should the switch be mounted inside an industrial enclosure?
• The unit is engineered for standard DIN-rail mounting within a properly rated industrial control cabinet.
