Technical Dossier

Product Details And Specifications

The Allen-Bradley 1756-DNB is a DeviceNet scanner module designed for the ControlLogix platform, enabling deterministic communication between PLCs and field-level DeviceNet devices — sensors, drives, and actuators — across discrete manufacturing and process automation environments. As Rockwell Automation progressively shifts its portfolio toward EtherNet/IP-centric architectures, the 1756-DNB occupies a critical position: it remains the backbone of legacy DeviceNet networks in industries where a full migration is cost-prohibitive or operationally disruptive.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Q: Is the 1756-DNB still in production?
A: The 1756-DNB is a mature product. Rockwell Automation continues to support it but has not announced an end-of-life date as of this writing. Procurement teams should monitor Rockwell's Product Lifecycle Status page and consider stocking strategic spares if their installed base is significant.
