Engineering Advantages

• High-Current Relay Switching: Each of the 8 relay outputs handles up to 3A at 230V AC. This allows the PLC to drive solenoid valves, motor starters, and heavy-duty contactors directly without requiring intermediate interposing relays, saving significant cabinet space and wiring costs.

• Flexible Input Filtering: The software-configurable input delay (0.1 ms to 32 ms) effectively eliminates mechanical contact bounce and electrical noise. This ensures the CPU receives clean, stable signals even in environments with high electromagnetic interference.

• Streamlined 2/3-Wire Connection: The module natively supports both 2-wire and 3-wire sensor types. This flexibility simplifies the integration of various proximity switches and sensors without requiring additional terminal blocks or complex wiring schemes.

• Hot-Swappable Density: The DX522 docks onto a standard S500 terminal base. This design allows for rapid hardware replacement while keeping the field wiring intact, drastically reducing Mean Time to Repair (MTTR) during maintenance cycles.

• Visual Fault Isolation: Clear, front-facing LED status indicators provide immediate visual confirmation of I/O activity. Maintenance teams quickly identify failed field devices or wiring breaks without needing a laptop or diagnostic software.

FAQs

• Can the DX522 relay outputs control DC loads?

  Yes. While the module excels at 230V AC switching, the potential-free relay contacts also manage DC loads. You must ensure the current and voltage stay within the specified relay contact ratings to prevent arcing or premature wear.

• What is the benefit of the configurable input delay?

  It prevents "ghost" signals caused by electrical spikes or mechanical vibration. For high-speed applications, set a low delay; for noisy environments with mechanical limit switches, a higher delay provides superior signal stability.

• Does this module require a separate terminal base?

  Yes. The DX522 module requires a compatible S500 Terminal Base (such as the TU515 or TU516) for physical mounting and electrical connection. The terminal base handles all field wiring, allowing the electronic module to plug in securely.

• Is this module compatible with all AC500 CPUs?

  The DX522 integrates with the entire AC500 and AC500-eCo range. It communicates via the local I/O bus when mounted next to the CPU or via decentralized bus couplers for remote I/O configurations.
