Düşündiriş

Product Overview

The Allen-Bradley 1783-US8T is a reliable Stratix 2000™ unmanaged Ethernet switch designed for simple, plug-and-play connectivity in industrial automation environments. Featuring eight (8) RJ45 Fast Ethernet ports, this switch provides an easy way to expand your network without the need for complex configuration. Its compact, open-style design is optimized for DIN rail mounting within control panels, offering a cost-effective solution for connecting controllers, HMIs, and other Ethernet-enabled field devices.

Technical Configuration

  • Manufacturer: Rockwell Automation / Allen-Bradley
  • Model Series: Stratix 2000
  • Catalog Number: 1783-US8T
  • Port Count: 8 RJ45 Copper Ports (10/100 Mbps)
  • Power Input: 24V Nominal (Supports 12-48V DC or 18-30V AC)
  • Switch Type: Unmanaged (Plug-and-Play)
  • Mounting: DIN Rail Mount (Open-style rating)

Technical Specifications

Net Weight 0.38 kg (0.84 lbs) Operating Temp 0 to 60°C (32 to 140°F)
Dimensions (HxWxD) 114.5 x 45.6 x 76.8 mm Inrush Current 1.31 A (Maximum)
Power Consumption 4.6 W; Wiring Category 1 (Power) & Category 2 (Communication)

Installation & Powering Features

1. Versatile Power Options: The 1783-US8T is highly flexible regarding power sources. It accepts a wide range of DC voltages (12-48V) and can also be powered by 24V AC, making it compatible with various machine power distribution standards. To ensure safety, the power input must be supplied by a SELV (Safety Extra Low Voltage) source.

2. Grounding Requirements: For reliable operation and noise immunity, the switch requires a functional earth connection. It is recommended to use 2.5 mm² (14 AWG) copper wire with a suitable ring terminal for the grounding lug, ensuring the wire is rated for at least 30°C above the surrounding ambient temperature.

3. Space-Saving Design: With a narrow width of approximately 45.6 mm, the 1783-US8T is designed to fit into crowded control cabinets. The "open-style" rating means the switch should be installed in an appropriate industrial enclosure (such as a NEMA or IP rated cabinet) to protect the internal components from environmental contaminants.

Engineering Advantages

The Stratix 2000 series removes the technical barrier to industrial networking. The 1783-US8T automatically negotiates speed and duplex settings for each connected device, eliminating the need for IT intervention or software management. With a maximum power consumption of only 4.6W and robust vibration/shock resistance, this switch is engineered for long-term stability in factory floor environments where reliability is paramount for non-stop production cycles.

Technical FAQs

Q1: Does this switch support Gigabit speeds?
A1: No, the 1783-US8T features Fast Ethernet ports with speeds up to 100 Mbps, which is sufficient for the majority of industrial I/O and PLC communication tasks.

Q2: Can I use fiber optic connections with this model?
A2: This specific model (1783-US8T) features 8 RJ45 copper ports only. For fiber optic capability, you would need a Stratix 2000 model that includes SFP ports.

Q3: Is any configuration software required for startup?
A3: No. As an unmanaged switch, the 1783-US8T works immediately upon power-up and connection to the network.
