Description
Product Name: 1738-IA2M12AC4 Allen Braley Input module
Product details:
The Allen-Bradley 1738-IA2M12AC4 is a member of the ArmorPoint I/O family. This series is designed for “on-machine” applications, meaning the hardware is rugged enough to be mounted directly on equipment without the need for a protective electrical cabinet.
Product Description
The 1738-IA2M12AC4 is a 2-channel, 120V AC Digital Input Module. It utilizes M12 micro-connectors for quick and reliable field device connectivity. As part of the ArmorPoint system, it communicates via a network interface (such as EtherNet/IP or DeviceNet) and is known for its high ingress protection and modularity.

Product Advantages
-
Cabinet-Free Installation: Because of its high IP ratings (up to IP69K), it can be mounted directly on the machine, drastically reducing the cost of enclosures and wiring runs.
-
Rugged Reliability: Built to withstand washdowns, dust, and vibration, making it ideal for food/beverage and heavy industrial environments.
-
Hot-Swapping: Supports “Removal and Insertion Under Power” (RIUP), allowing you to replace modules without shutting down the entire system.
-
Simplified Diagnostics: Features integrated status LEDs for network communication and individual I/O status to speed up troubleshooting.
Key Considerations & Precautions
-
Proper Grounding: Ensure the mounting surface or the DIN rail is properly grounded to prevent electrical noise issues.
-
Connector Torque: To maintain the IP67/IP69K seal, M12 connectors must be tightened to the manufacturer’s specified torque.
-
Voltage Separation: Keep high-voltage AC wiring separated from low-voltage DC communication lines to avoid electromagnetic interference (EMI).
-
Module Compatibility: Ensure the communication adapter (e.g., 1738-AENT) has sufficient backplane current to support the total number of modules in the stack.
Typical Applications
-
Food and Beverage: Packaging and bottling lines that require frequent high-pressure washdowns.
-
Automotive Assembly: Distributed I/O across large conveyor systems where local control is needed near sensors.
-
Material Handling: Sorting systems and warehouses where mounting I/O on the frame saves space.
-
General Manufacturing: Any environment where space in electrical rooms is limited and “On-Machine” distribution is more efficient.
