Allen-Bradley 1734-IB4 – 4-Point Digital Input Module for Industrial Automation

The Allen-Bradley 1734-IB4 is a compact digital input module designed for use in distributed I/O systems under the POINT I/O platform. It supports four sinking-type input channels at 24 V DC, making it suitable for reading signals from sensors, switches or other binary devices in industrial control environments. Its modular design and DIN-rail mounting allow seamless integration into control cabinets and scalable automation architectures.

Key features and benefits:
• 4-channel digital input (sinking) module for 24 V DC signals 
• Compact dimensions (approx. 56 × 12 × 75.5 mm) and DIN-rail mounting for easy installation 
• Low input current per channel — efficient for typical sensor/switch loads 
• Modular POINT I/O system compatibility — allows combining multiple I/O modules, easy expansion, and flexible wiring base options 
• Reliable performance with reinforced insulation, suitable for industrial environments

Typical applications:
• Reading digital signals from sensors, switches, push-buttons in automation systems
• Input channels for machine control panels, conveyor systems, safety interlocks
• Distributed I/O architectures for manufacturing lines and process automation
• Status monitoring of equipment — on/off states, limit switches, presence sensors
• Integration into modular PLC / I/O cabinets for flexible control setups
