Key Functional Characteristics
Certified Safety Performance:TheDX581-Sis engineered for critical protection tasks. Both its inputs and outputs are designed with internal redundancy and self-diagnostic features to detect wiring faults, short circuits, or hardware failures, ensuring the machine enters a safe state if an anomaly occurs.
High-Density Safety I/O:Despite its small 76 mm wide frame, the module provides a total of 16 safety points. This high density allows for complex safety logic implementation—such as two-hand control, muting functions, and synchronized shutdown sequences—without occupying excessive DIN rail space.
Seamless AC500-S Integration:The module utilizes the PROFINET/PROFIsafe protocol when connected to the AC500-S safety CPU. This allows for rapid signal exchange and advanced diagnostics, enabling operators to identify exactly which safety device was triggered directly from the HMI or control system.
