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
The Shift to Flexible IO Modules in Modern Industrial Automation
Traditional control systems rely on dedicated Input Output (IO) cards for industrial automation. Each conventional module processes a single signal type, such as Digital Input (DI), Digital Output (DO), Analog Input (AI), or Analog Output (AO). A standard 16-channel card accepts only one specific channel type across all ports. This inflexible hardware design often creates severe engineering bottlenecks during project execution. Engineers frequently must install entirely new cards to accommodate a single extra sensor. Consequently, late design changes increase control cabinet space requirements and drive up project costs.
DCS Commissioning Steps in Industrial Automation Projects
Commissioning a Distributed Control System (DCS) represents a crucial milestone when deploying modern process automation infrastructure. Field engineers must execute systematic verification steps to transition complex control hardware from static installation to dynamic plant control. Proper commissioning ensures that controllers, I/O modules, network switches, and HMI software operate in strict compliance with engineering design specifications before introducing live process fluids.
PLC and DCS Control System Spares Strategy: Engineering Guidelines
Modern factory automation relies on high-speed fiber optic backbones to link distributed control systems across noise-intensive industrial environments. Unlike copper wiring, optical fibers transmit data via light pulses, making them completely immune to electromagnetic interference (EMI). Field engineers must master optical cable joining and fusion splicing techniques to guarantee low-loss data transmission across critical Programmable Logic Controller (PLC) and Distributed Control System (DCS) nodes.
