Allen-Bradley 1756-ENBT SER A Module
The Allen-Bradley 1756-ENBT SER A is a new EtherNet/IP communication module designed for ControlLogix chassis. It provides a network interface for industrial automation systems requiring Ethernet connectivity. This switch module integrates into existing control architectures to enable data exchange between processors and field devices.
Suits ControlLogix EtherNet/IP networks
Engineers expanding or maintaining a ControlLogix system with EtherNet/IP will use this module to add or replace a network port. It is not suitable for systems using different backplane architectures or communication protocols. Buyers needing fibre ports, managed switching features or higher port counts should look at other hardware.
Series A hardware revision
The critical detail is the Series A designation, which defines the hardware revision and firmware compatibility window for the 1756 platform. Confirm that the target chassis and controller firmware support this revision before purchase. The module was first listed by the manufacturer in 2022.

Questions about this item
How do I install the 1756-ENBT SER A module into a ControlLogix chassis?
Power down the chassis, align the module with an available slot, slide it in until the latch clicks securely, then restore power and configure the network settings through the programming software.
What maintenance or replacement will the 1756-ENBT SER A module need over time?
The module has no user-serviceable parts; maintenance is limited to keeping the chassis ventilation clear and checking cable connections, while replacement is only required if the unit fails.
What limit appears first on the 1756-ENBT SER A during sustained high-traffic operation?
The module’s EtherNet/IP connection capacity and bandwidth ceiling will be reached before any thermal or power threshold under continuous heavy load.
