Real-World Applications

Commonly deployed in packaging lines, conveyor systems, and material handling equipment, this module handles discrete control tasks while maintaining communication with higher-level systems. We’ve supplied these to automotive plants for robotic cell coordination, and to food processing facilities for valve actuation sequences.

Our inventory includes complementary components like Allen-Bradley 1794-IB16 modules, Siemens 6ES7 321-1BH02-0AA0 interfaces, and Schneider Modicon 140DDI35300 cards. For instance, a recent customer integrated this module with their existing Rockwell ControlLogix system to expand I/O capacity without protocol conversion.
