1734-IB8 24V DC Digital Input Module | Allen-Bradley

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

Technical Specifications and Electrical Data

• Allen-Bradley designs the 1734-IB8 as a digital DC sinking input module featuring eight input channels in one group.
• Input voltage category operates at 24V DC nominal with an acceptable range from 10V DC to 28.8V DC.
• Input current range spans 2 mA to 5 mA with nominal current of 4 mA at 24V DC.
• Maximum input current per channel measures 5 mA ensuring compatibility with standard industrial sensors.
• POINTBus current consumption draws 75 mA at 5V DC from the backplane for efficient power usage.
• Power dissipation reaches 1.6 Watts with thermal dissipation of 5.5 BTU/hour at maximum ratings.
• Input filter time combines 0.5 ms hardware delay with user-selectable software settings from 0 to 63 ms.
• Isolation voltage provides 50V continuous between field and system sides with reinforced insulation tested at 2500V DC for 60 seconds.
• Dimensions measure 56 x 12 x 75.5 mm (2.2 x 0.47 x 2.97 in.) with a compact form factor for space-saving panels.
• Weight approximates 31.8 g (1.12 oz) contributing to lightweight assembly on DIN rails.
• Enclosure carries an open-style rating requiring installation within a protected enclosure.
• Keyswitch position sets to 1 preventing mismating with other module types in the system.
• Terminal base screw torque requires 0.8 N-m (7 lb-in) for secure field wiring connections.
• Operating temperature range spans -21 to 55 degrees Celsius for reliable industrial performance.
• Mounting orientation supports both horizontal and vertical DIN rail installations for flexibility.

Terminal Base Requirements and Mechanical Mounting

• The 1734-IB8 requires either a 1734-TB or 1734-TBS wiring base assembly for proper installation.
• Mount the terminal base on a DIN rail using zinc plated yellow chromate steel for proper grounding.
• Secure the DIN rail to the mounting surface every 200 mm (7.8 inches) using appropriate anchors.
• All field wiring connects through the removable terminal block on the wiring base assembly.
• The module features a locking mechanism and side-in writable label for easy identification.
• Installation requires a compatible POINT I/O communication adapter to supply backplane power and network connectivity.
