Allen-Bradley 1734-IB8 POINT I/O Input Module

Product Overview

The is a used in .

It is part of the , working with an adapter like:

• 1734-AENT / 1734-AENTR (EtherNet/IP)
• 1734-ADN (DeviceNet)

Key Specifications (confirmed)

• Allen-Bradley (Rockwell Automation)

• POINT I/O (Bulletin 1734)

• 1734-IB8

• 8 digital inputs

• 24V DC sinking (NPN style field devices)

• ~10–28.8 VDC

• ~2–5 mA per channel

• ~0.5 ms hardware + configurable filter

• DIN rail with terminal base (1734-TB / 1734-TBS)

• removable terminal base system

• 8 channel LEDs + module status LED

• −20°C to +55°C

What It Does (Simple Explanation)

This module is used to , such as:

• push buttons
• limit switches
• proximity sensors
• safety signals (non-safety version)

Workflow:

• Sensor turns ON (24V signal)
• 1734-IB8 reads input
• Data is sent via POINT I/O network adapter
• PLC (CompactLogix / ControlLogix) processes logic

Key Features

• Compact modular design (POINT I/O system)
• 8-channel high-density input
• Hot-swappable (can replace without full shutdown in many setups)
• LED diagnostics per channel
• Flexible wiring via terminal base
• Works with EtherNet/IP, DeviceNet, etc. (via adapter)

Advantages

• Saves cabinet space (distributed I/O)
• Reduces wiring from field to PLC
• Easy expansion (add modules one by one)
• Fast diagnostics (channel LEDs)
• Widely used in Rockwell automation systems

Applications

• Industrial machine control systems
• Packaging equipment
• Conveyor systems
• Assembly lines
• Factory automation I/O expansion
• Remote sensor monitoring
