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.

FAQ
- What does sourcing output mean in this module?
Sourcing output means the module provides positive voltage to the load, typically used with devices that require a current source from the output. - What types of devices can be connected to the outputs?
It can control solenoid valves, relays, indicator lights, and other DC-powered industrial devices. - What is the advantage of using M8 connectors?
M8 connectors allow quick and reliable connections, reducing installation time and minimizing wiring errors. - Is the module suitable for washdown environments?
Yes, the IP69K rating ensures it can withstand high-pressure cleaning and harsh conditions. - Can it be mounted directly on equipment?
Yes, it is designed for on-machine mounting without requiring additional protective enclosures. - How many outputs can be controlled simultaneously?
All 8 outputs can be controlled independently and simultaneously, depending on system configuration. - Does it require a separate power supply?
Yes, a 24 VDC power supply is required to drive the outputs and connected loads. - How does it integrate with the control system?
It connects through an ArmorPoint network adapter, which communicates with the controller via EtherNet/IP. - What happens if an output is overloaded?
Overloading may lead to reduced performance or shutdown of the affected channel, depending on system protection mechanisms. - What is the benefit of using distributed output modules?
They reduce wiring distances, improve system flexibility, and allow control functions to be placed closer to field devices.
