Overview
The DL-PC/104 is a plug-and-play PC/104 interface card designed to bridge PCs and MMI (Man-Machine Interface) systems to Allen-Bradley DH+ and Remote I/O (RI/O) networks. This adapter leverages the PC/104 standard—a rugged, stackable embedded computing form factor—to provide reliable serial communication in industrial automation environments.
Key Features
- PC/104 plug-and-play connector for easy installation in embedded systems
- Uses existing Allen-Bradley DF1 COM port drivers—no new software investment required
- Support for DataHighway Plus (DH+) and Remote I/O (RI/O) protocols
- Lower total cost of ownership compared to dedicated AB interface cards
- Compact form factor suitable for space-constrained control cabinets and distributed I/O applications
- Proven compatibility with legacy and modern PC-based automation platforms
