Allen Bradley 1783-USP8T Stratix 2000 Unmanaged Ethernet Switches

Applications

The Allen Bradley 1783-USP8T is a compact Stratix 2000 unmanaged Ethernet switch designed to provide straightforward industrial network connectivity without the configuration requirements associated with managed switches. It is suitable for machine-level networks, small control systems, and applications where Ethernet devices need to be connected quickly and reliably.

The switch can be used to connect PLC controllers, remote I/O, HMIs, drives, industrial computers, sensors, and other Ethernet-enabled automation equipment. Its compact construction makes it particularly practical for installation inside machine control panels and smaller electrical enclosures.

Typical applications include:

• Machine-level Ethernet networks
• PLC and remote I/O connections
• HMI and controller communication
• Industrial drive networking
• Control cabinet Ethernet distribution
• Small automation cells
• Packaging and material-handling equipment
• Factory-floor device connectivity 

Advantages

Simple Unmanaged Operation

The 1783-USP8T operates without requiring complex network configuration. This makes it suitable for applications where basic Ethernet switching is required and advanced managed-switch functions are not necessary.

Compact Industrial Design

With dimensions of only 114 × 26 × 70 mm, the switch can be installed in space-constrained control cabinets, machine panels, and automation enclosures.

Fast Network Deployment

Because the switch does not require extensive configuration, installation can be straightforward. Connected Ethernet devices can communicate through the switch once the physical network is correctly wired.

Suitable for Machine-Level Networks

The Stratix 2000 family is well suited to smaller industrial networks where PLCs, HMIs, I/O devices, and other Ethernet-based components need a simple communication infrastructure.

Low Installation Weight

At 0.353 kg (0.78 lb), the 1783-USP8T places little additional mechanical load on a control cabinet or machine-mounted enclosure.

Technical FAQs

1. What is the Allen Bradley 1783-USP8T used for?

The 1783-USP8T is an unmanaged industrial Ethernet switch used to connect multiple Ethernet devices within automation and control networks.

2. What is the difference between an unmanaged and managed Ethernet switch?

An unmanaged switch provides basic Ethernet switching without requiring network configuration, while a managed switch normally provides additional functions such as VLAN configuration, diagnostics, traffic management, and network monitoring.

3. Is the 1783-USP8T suitable for PLC networks?

Yes. It can be used to provide Ethernet connectivity between compatible PLCs and other industrial Ethernet devices in machine-level or control-system networks.

4. Does the 1783-USP8T require software configuration?

As an unmanaged switch, it is designed for operation without the network configuration normally required for a managed switch. The connected devices themselves still need to be configured correctly for the overall automation system.

5. Where is the 1783-USP8T typically installed?

It can be installed in machine control panels, electrical cabinets, automation enclosures, and other locations where industrial Ethernet devices require local network connectivity.

6. Can the switch connect HMIs and PLCs on the same Ethernet network?

Yes. When the connected devices use compatible Ethernet communication, the switch can provide the physical network connection between PLCs, HMIs, and other Ethernet devices.

7. What could cause a connected device to lose Ethernet communication?

Possible causes include a damaged Ethernet cable, loose connector, incorrect device configuration, power loss, a faulty network port, or a problem with the connected automation equipment.

8. How should the 1783-USP8T be integrated into an automation network?

The switch should be positioned where it can provide the required Ethernet connections while keeping cable routing organized. Network architecture, power requirements, environmental conditions, and applicable installation requirements should also be considered.

9. Is an unmanaged switch appropriate for every industrial network?

Not necessarily. Unmanaged switching is appropriate for simpler networks where advanced network management is not required. Larger or more complex systems may require managed networking equipment for diagnostics, segmentation, redundancy, or traffic control.

10. What should be checked when troubleshooting the 1783-USP8T?

Check the switch power supply, Ethernet cables, connector seating, link indicators, connected device status, and network topology. If the physical connections are correct, test the affected Ethernet device and cable separately to isolate the source of the communication problem.
