Allen-Bradley 1738-IB8M8 ArmorPoint 8-Point Digital Input Module

Product Overview

The Allen-Bradley 1738-IB8M8 serves as a rugged 8-point digital input module designed specifically for the ArmorPoint distributed I/O system. Engineered to operate directly in harsh industrial environments, this module features a sealed IP67 housing and durable M8 (Pico) connectors, eliminating the need for protective control cabinets. It provides 8 non-isolated sinking inputs at 24V DC, allowing engineers to mount automation controls directly on machinery, conveyors, and processing equipment exposed to dust, moisture, and extreme temperatures. We supply this item as a 100% Brand New, factory-sealed unit.

Technical Specifications

Engineering Advantages

Rugged IP67 Sealed Housing for Harsh Environments
The 1738-IB8M8 is built to withstand the toughest factory floor conditions. Its fully sealed IP67-rated housing protects internal electronics from dust, dirt, oil, and water ingress. This allows you to mount the module directly on machinery or in washdown areas without requiring an expensive, space-consuming protective control cabinet.

Durable M8 (Pico) Connectivity
Equipped with standard M8 (Pico) connectors, this module ensures quick, secure, and vibration-resistant connections to field sensors and switches. The robust connector design simplifies installation and maintenance in high-vibration applications, significantly reducing wiring time and eliminating loose connection faults common with traditional terminal blocks.

Extreme Temperature Operational Range
Engineered for thermal resilience, the 1738-IB8M8 operates flawlessly in ambient temperatures ranging from -20°C to 60°C (-4°F to 140°F). It also withstands storage temperatures as low as -40°C (-40°F), making it an ideal choice for unheated warehouses, outdoor automation systems, and cold storage facilities.

FAQs

Q: What is the environmental protection rating of the 1738-IB8M8?
A: This module features a sealed IP67-rated housing, which provides complete protection against dust ingress and safeguards against temporary immersion in water, making it perfect for harsh industrial environments.

Q: What type of input configuration does this module use?
A: The 1738-IB8M8 provides 8 non-isolated sinking inputs. This means the module acts as the current sink, and your field devices (such as proximity sensors or limit switches) must source 24V DC to activate the inputs.

Q: What kind of connectors does the 1738-IB8M8 use for field wiring?
A: It uses M8 (Pico) connectors. These compact, threaded connectors provide a secure and vibration-resistant connection, which is standard for ArmorPoint I/O systems designed for direct machine mounting.

Q: What is the operating temperature range for this input module?
A: The 1738-IB8M8 is rated to operate continuously in temperatures ranging from -20 to 60 degrees Celsius (-4 to 140 degrees Fahrenheit), ensuring stable performance in both hot and cold industrial settings.
