Allen-Bradley 1492-DN3TW DIN Rail Terminal Block

Allen-Bradley 1492-DN3TW is a DeviceNet open-style terminal block rail assembly that mounts on a 56 mm DIN rail to provide a five-block terminal strip in a single compact unit, enabling straightforward distribution of DeviceNet wiring and efficient field modifications. The kit includes five 1492-J3TW terminal blocks colored red, white, gray, blue, and black, a matching end barrier 1492-EBJ3, end anchors 1492-ERL35, and pre‑printed M5x12 markers for labeling (Red, White, Drain, Blue, Black), supporting clear, color-coded conductor organization and documentation on the panel. A Bill of Materials entry for this assembly lists a 199-DR1 1-meter DIN rail segment cut to 56 mm, indicating the exact rail length required for installation and confirming a 56 mm footprint on the DIN rail. This assembly is designed for DeviceNet networks, consolidating device terminations and open-style tapping in a standardized DIN-rail form factor that simplifies wiring, maintenance, and scalability in compact control cabinets.
