Description
The Allen-Bradley 1492-AIFM8-3 is an 8-channel feed-through Analog Interface Module (AIFM) designed to simplify field wiring for PLC analog I/O systems. This module serves as a bridge between field devices and the controller, providing a clean, organized termination point that reduces the need for external terminal blocks and jumper accessories. It features 3 terminals per input channel, allowing for efficient signal, common, and shield connections.
Features
- 8-channel feed-through design for streamlined analog signal management.
- 3 terminals per input channel to support signal, common, and shield wiring.
- Integrated power bus with eight extra terminals jumpered together for common or power supply distribution.
- Internal jumpering to the D-shell housing for effective shield grounding.
- Compatible with various PLC analog I/O cards, facilitating faster panel assembly and maintenance.
Applications
This interface module is widely used in industrial control panels where high-density analog I/O is required. It is commonly deployed with Allen-Bradley SLC 500 and ControlLogix systems to interface with sensors, transmitters, and actuators, ensuring reliable signal integrity and simplified troubleshooting.
