Allen-Bradley 1738-IB8M8 24V DC Sink 8-Input M8 Module

Allen-Bradley 1738-IB8M8 ArmorPoint 8-Point 24V DC Sink Input Module

Product Description

The Allen-Bradley 1738-IB8M8 (Catalog Number: 1738-IB8M8) is a high-durability digital input module designed for the ArmorPoint I/O system. Engineered for decentralized automation, this module provides 8 points of 24V DC sinking inputs. Its defining feature is the integration of eight M8 quick-disconnect connectors, which allow for a highly compact footprint compared to standard M12 versions. This makes the 1738-IB8M8 an ideal choice for space-constrained on-machine applications where high-density sensor feedback is required.

As a core component of the ArmorPoint family, the 1738-IB8M8 is built to withstand the rigors of the factory floor without an electrical cabinet. The module is fully encapsulated with an IP67/IP69K rating, offering complete protection against dust, high-pressure water jets, and steam cleaning. It connects to the control system via a communication adapter (such as EtherNet/IP), supporting real-time data acquisition and diagnostics for individual input points through the Studio 5000 Logix Designer environment.

Technical Specifications

Hardware parameters and environmental ratings for the 1738-IB8M8:

Key Features

• Ultra-Compact M8 Interface: Utilizes smaller M8 connectors to provide 8-point density in a slim, machine-mountable form factor.

• On-Machine Durability: Eliminates the need for enclosures with IP69K sealing, suitable for wash-down zones in food and beverage or automotive plants.

• Reduced Latency: High-speed signal processing ensures rapid response for proximity sensors and operator pushbuttons.

• Plug-and-Play Installation: Quick-disconnect ports reduce wiring errors and significantly decrease time-to-commission for OEMs.

• Diagnostic Visibility: Integrated LEDs provide status feedback for individual input channels and overall module health.

Industrial Application Scenarios

• Robotic Tooling: Mounting directly on robot arms where space is limited and sensors require localized I/O.

• Food & Beverage: Reliable operation on conveyors and packaging lines subject to daily high-pressure chemical cleaning.

• Small Machine Skids: Ideal for modular equipment where a traditional control cabinet is not feasible or necessary.

• Material Handling: Providing high-density sensing for sorters and automated storage systems.
