Technical specifications for 1734-IB8
Allen-Bradley 1734-IB8 | POINT I/O Digital Input Module
The Allen-Bradley 1734-IB8 is a compact and high-performance 8-point DC sinking digital input module from the trusted POINT I/O series by Rockwell Automation. Designed for industrial automation systems, the 1734 IB8 offers 8 sinking inputs, supporting a voltage range of 10–28.8V DC, with a nominal input voltage of 24V DC and nominal input current of 4 mA @ 24V DC. This AB 1734 IB8 module ensures fast and reliable signal processing with an input filter time of 0.5 ms hardware plus 0–63 ms user-selectable, while drawing 75 mA from the POINTBus @ 5V DC. With a power dissipation of 1.6 W and thermal dissipation of 5.5 BTU/hour, it is engineered for efficiency.
The 1734IB8S includes intuitive status indicators: a green/red module status LED and 8 yellow input status LEDs, providing real-time diagnostic visibility. Reverse polarity protection safeguards the module from incorrect wiring. It mounts on 1734-TB or 1734-TBS terminal bases and fits securely in control cabinets with its open-style enclosure, measuring just 56 x 12 x 75.5 mm and weighing approximately 31.8 grams. Whether referred to as 1734ib8, AB 1734 IB8, or Allen Bradley 1734 IB8, this module stands out for its reliability and flexibility in distributed control applications.
