1734 IB8 Digital Input Module Allen Bradley

Product Overview

The Allen Bradley 1734 IB8 is a high-performance 8-channel digital input module from the POINT I/O™ series, designed for seamless integration into distributed I/O systems. Engineered for industrial automation, it reliably collects 24V DC sinking input signals from sensors (e.g., proximity switches, limit switches) and devices, converting them into controller-readable logic levels. Ideal for applications requiring precise signal acquisition, such as equipment monitoring, process control, and safety circuits, the module delivers robust performance in harsh environments.

Key Features

• 8-Channel Sinking Input: Supports 8 independent 24V DC sinking input channels with a voltage range of 10–28.8V DC and current of 2–5mA.
• Flexible Filtering: Combines a 0.5ms fixed hardware filter with a user-configurable 0–63ms filter to suppress signal noise while maintaining fast response times (≤1ms).
• Diagnostic Capabilities: Detects input faults (e.g., overvoltage, short circuits) and feeds back status to the control system for proactive maintenance.
• Seamless Integration: Compatible with POINT I/O communication adapters (EtherNet/IP™, DeviceNet™, PROFIBUS) and works with CompactLogix™/ControlLogix® controllers.
• Compact Design: Width of just 12.7mm for space-saving installation in control cabinets; supports DIN rail mounting.
• Hot-Swap Support: Enables module replacement without system shutdown, minimizing production downtime.
• Visual Status Indicators: 8 green LEDs for channel status and 1 network LED for power/communication health.
