Excellent PLC
Product Introduction
The Allen Bradley 1738-OB16EM12 ArmorPoint Digital Output Module is a high-density digital output module developed for the ArmorPoint I/O platform by Rockwell Automation. It provides 16 digital output channels and is designed for direct on-machine installation in demanding industrial environments.
Unlike traditional cabinet-mounted I/O, this module is built with a sealed housing that allows it to operate reliably in exposed conditions such as dust, moisture, and vibration. It eliminates the need for protective enclosures, significantly reducing installation complexity and system cost in distributed automation architectures.
The 1738-OB16EM12 is engineered to deliver stable 24 VDC output signals to field devices such as actuators, solenoids, and indicators. With its compact design and M12 connectivity, it enables efficient wiring, fast deployment, and reliable long-term operation in modern industrial systems.
