Product Details
Product Description
The 1738-OB8EM8 is a high-durability distributed I/O module from the Allen-Bradley ArmorPoint family, specifically engineered for "on-machine" applications. This module facilitates decentralized control by allowing the mounting of I/O points directly on machinery, significantly reducing cabinet space requirements and complex wiring runs. It features eight non-isolated sourcing DC outputs, making it ideal for driving actuators, solenoids, and indicators in a 24V DC architecture.
Built to withstand rigorous industrial conditions, the 1738-OB8EM8 (Part Number: 1738-OB8EM8) is housed in a robust, IP67-rated sealed enclosure that provides superior protection against dust, water jets, and coolant immersion. Connection is achieved via industry-standard M8 (Pico) connectors, ensuring a secure, vibration-resistant interface that is critical for automotive, material handling, and food and beverage processing lines.

Operational Scenarios
The ArmorPoint 1738-OB8EM8 is the preferred choice for industrial environments where a traditional control cabinet is too far from the field devices or where the machine environment is too wet for standard IP20 modules. Its compact M8 footprint allows for high-density output clusters on robotic arms or modular conveyor segments.
Technical FAQ
What is the significance of the "EM8" suffix in this ArmorPoint module?The "E" denotes electronic fusing or enhanced diagnostics capabilities common in the ArmorPoint line, while "M8" specifies the physical connector standard. This allows for rapid replacement of cables without the risk of wire transposition.
Does this module require a separate mounting base?ArmorPoint modules like the 1738-OB8EM8 are designed to be part of a larger assembly. While they are "on-machine" rated, they must be correctly integrated into the ArmorPoint backplane structure and power bus to function within the network (such as EtherNet/IP or DeviceNet).

Tech & Buying Guide
Mastering Modern Industrial Joystick Controls in Heavy Automation
Industrial joysticks play a pivotal role in human-machine interaction across heavy material handling and mobile hydraulics. These tactile controllers translate complex operator movements into precise electrical signals for PLCs, motion controllers, and DCS networks. Consequently, selecting and installing the right joystick architecture ensures operator safety, reduces fatigue, and optimizes equipment performance.
Navigating Industrial Automation Failures: Types, Causes, and Mitigation Strategies
Modern manufacturing relies heavily on automated control systems to maximize throughput and maintain product quality. However, unplanned downtime in industrial automation can cost facility operators thousands of dollars per hour. Understanding how programmable logic controllers (PLCs), distributed control systems (DCS), and field instrumentation fail empowers engineering teams to implement robust preventive maintenance strategies.
Essential Motion Control Commands: A Practical Guide for Engineers
Automation engineers often rely on precise position and speed control to drive modern factory machinery. Modern industrial systems, such as Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS), depend heavily on standardized motion instructions. Mastering these commands ensures operational safety, protects mechanical components, and optimizes cycle times across production lines.
