1734-IB8 POINT I/O 8-Channel DC Input Module Allen-Bradley

Allen-Bradley 1734-IB8 Technical Overview

The Allen-Bradley 1734-IB8 is a compact digital DC input module belonging to the Allen-Bradley POINT I/O product family, manufactured by Rockwell Automation. Designed for distributed I/O architectures via communication adapters, this module features eight (8) discrete sinking input channels operating at a nominal voltage of 24VDC (10–28.8VDC input range). Weighing approximately 31.8 g (1.12 oz) with dimensions of 56 x 12 x 75.5 mm, it requires a 1734-TB or 1734-TBS terminal base assembly, draws 75 mA of POINTBus current at 5V DC, dissipates 1.6 Watts, and operates reliably across surrounding air temperatures from -21 °C to 55 °C.
