Product Overview
The Allen-Bradley 1734-IB4 is a compact digital DC sinking input module from the popular POINT I/O product family by Rockwell Automation. Designed to support distributed I/O architectures, this module features 4 sinking input channels operating on a 12/24V DC voltage category. Drawing a maximum input current of 5 mA with a low power dissipation of 1W (3.4 BTU/hour), the 1734-IB4 integrates smoothly with any POINT I/O communication adapter and POINTBlock I/O modules via the 75 mA POINTBus backplane. Featuring physical dimensions of 56 x 12 x 75.5 mm and an ultralight net weight of 31.8 g (1.12 oz), this open-style DIN rail module optimizes panel space while providing reliable real-time status indication and robust field connection.
