Key features
Multi-connection capability: supports a large number of I/O and message connections, suitable for multiple devices to communicate concurrently.
Advanced network diagnostics: provides real-time network health status, connection status, data packet loss rate and other information through Studio 5000.
High security: supports CIP security features, which can control access to communications.
Hot-swap support: can be plugged and unplugged during operation without powering off.


Typical cooperation cases
Chevron Refinery in the United States: Real-time communication between DCS and SIS systems is achieved through Allen-Bradley EN2T, improving data throughput and redundancy reliability.
Automation system upgrade of Singapore Pharmaceutical Group: Replace the original ENBT module with Allen-Bradley EN2T to improve production efficiency and support network security isolation strategy.
Urban sewage treatment project in the Middle East: Gigabit communication link is established between the control center and distributed pumping stations through Allen-Bradley EN2T to enhance control response.
Alternative models
Model | Feature Comparison |
1756-ENBT | Supports up to 100 Mbps, fewer connections (max 128), no DLR support; suitable for small to medium systems. |
1756-EN2T | Supports Gigabit Ethernet, more connections (up to 256), DLR support; significantly better performance, ideal for complex systems. |
1756-EN2TR | All EN2T features plus redundant communication ports (dual RJ-45); ideal for critical systems requiring network redundancy. |
1756-EN3TR | Higher data throughput support, suitable for large-scale systems; features triple-port design for enhanced scalability. |
summary:Allen-Bradley 1756-EN2T is an upgraded version of the ENBT and can seamlessly replace it in applications that require higher bandwidth and more complex control. However, if a system is already configured with an ENBT, caution should be taken regarding compatibility with existing IP settings and program downloads.
