Application Scenarios
In a packaging machinery line running WAGO 750 Series I/O nodes, engineers needed to capture high-speed registration mark signals from optical sensors at line speeds exceeding 200 packages per minute. Standard 3ms input modules were missing brief sensor pulses, causing misaligned labels and wasted material. Switching to WAGO 750-401 modules with their 0.2ms RC filter resolved the issue—the faster response time ensured every registration pulse reached the controller, cutting label waste by approximately 18% and eliminating the need for external signal conditioning hardware.
For machine builders integrating safety gate switches and position sensors into a distributed control architecture, the 750-401 provides direct connectivity for 2-, 3-, and 4-wire sensor configurations . The module’s high-side switching characteristic means a positive 24VDC signal at the input terminal registers as logic “high,” simplifying wiring for PNP sensors commonly found in European and Asian machine designs.
