1734-IB2 Allen-Bradley POINT I/O 24V DC Sinking Input Module

Allen-Bradley 1734-IB2 POINT I/O 24V DC 2-Channel Sinking Input Module

Key Technical Specifications

• The 1734-IB2 provides 2 sinking input channels configured as 1 or 2 groups of 2. It accepts 24 V DC nominal input voltage with a 10-28.8 V DC operating range.
• Maximum input current measures 5 mA per channel for reliable signal detection. POINTBus current draws 75 mA at 5 V DC from the backplane.
• Power dissipation reaches 0.7 W maximum at 28.8 V DC. Thermal dissipation measures 2.4 BTU/hour at 28.8 V DC for efficient heat management.
• Dimensions are 56 mm x 12 mm x 75.5 mm (2.2" x 0.47" x 2.97"). It weighs approximately 30.9 g (1.09 oz).
• Terminal base screw torque specification is 0.8 N·m or 7 lb-in for secure wiring connections.

Environmental & Mechanical Specifications

• The 1734-IB2 features an open-style enclosure rating. Operating temperature range is -20 °C to 55 °C (-4 °F to 131 °F).
• Non-condensing relative humidity tolerance spans 5% to 95%. The module withstands industrial vibration and shock standards for reliable operation.
• Its compact 12 mm width saves valuable panel space. The lightweight design makes installation quick and straightforward.
