Excellent PLC
Product Introduction
The Allen Bradley 1738-OB8EM8 ArmorPoint Digital Output Module is a compact and rugged discrete output module designed for the ArmorPoint I/O platform from Rockwell Automation. It provides 8 sourcing digital output channels and is engineered for reliable operation in harsh industrial environments where traditional cabinet-based I/O solutions are not suitable.
This module features a fully sealed construction with a high ingress protection rating, allowing it to be mounted directly on machines, production lines, or outdoor equipment. By eliminating the need for control cabinets, it significantly reduces wiring complexity and installation costs while improving system flexibility.
Equipped with M8 output connectors, the 1738-OB8EM8 supports quick and efficient wiring for field devices. Its robust design ensures stable output performance for controlling actuators, indicators, and other industrial loads in distributed automation systems.
