Technical Specifications

Installation & Application

1. Simplified Setup: The 1783-US5T requires no software configuration. Once mounted on a DIN rail and supplied with power, it automatically negotiates the fastest possible speed (up to 100 Mbps) and duplex mode for each connected device. The 512 kb packet buffer ensures efficient data handling even during high-traffic intervals.

2. Robust Powering: This switch is versatile enough to operate on both AC and DC power supplies (Nominal 24V). Its low power consumption of 3.4W reduces the thermal load within control cabinets, while its 15 g operating shock rating ensures stability in environments with moving machinery.

3. Compact Footprint: With its lightweight 300g housing, the 1783-US5T is designed for space-constrained enclosures. It provides a highly reliable mean time between failures (MTBF) of 1,000,000 hours, ensuring long-term service life in typical industrial temperature ranges of -10°C to +60°C.

Engineering Advantages

The Allen-Bradley 1783-US5T offers industrial-grade durability compared to standard commercial switches. By meeting UL/cUL safety ratings and featuring broadcast storm protection, it prevents network crashes that could otherwise disrupt manufacturing processes. Its unmanaged nature means it is immune to configuration errors and cybersecurity vulnerabilities associated with managed IP interfaces, providing a secure and straightforward hardware-based switching solution.

Technical FAQs

Q1: Can I use this switch for EtherNet/IP communication?
A1: Yes, the 1783-US5T is fully compatible with EtherNet/IP, though as an unmanaged switch, it does not support IGMP snooping for specialized multicast traffic management.

Q2: Does the module support Power over Ethernet (PoE)?
A2: No, the 1783-US5T is a standard data switch. It does not provide power to connected field devices via the RJ45 ports.

Q3: Is there a specific mounting orientation required?
A3: The switch is designed for vertical DIN rail mounting to allow for optimal convective cooling across the internal components.
