Allen-Bradley 1734D-IA16 DeviceNet Input Module

Allen-Bradley 1734D-IA16 DeviceNet Input Module is a DIN-rail mounted POINT I/O input block with an integrated DeviceNet interface that plugs into a DeviceNet network as a slave. It provides 16 AC input channels, wired through removable terminal blocks, and is designed for 120 V AC sensor and switch signals in industrial automation. The module is part of the 1734 POINT I/O family and supports DeviceNet communications with a node address selectable up to 63, enabling deterministic polling of input status by a Rockwell Automation controller. It offers standard PointBus expansion compatibility for linking with other Point I/O modules in a common chassis, and its DIN-rail mounting simplifies panel installation. Common applications include reading 16 discrete AC sensors or switches in manufacturing lines, packaging equipment, or process control where 120 V AC sensing is required, feeding status data to a PLC over DeviceNet. The 1734D-IA16 uses screw terminal input wiring for secure field connections and employs the rugged Point I/O design to withstand industrial environments.
