Features

• Direct 230V AC Control: Capable of switching mains-level voltages directly, reducing the need for interposing relays in the control cabinet.

• Per-Channel Isolation Architecture: Features independent galvanic isolation for every channel, providing superior protection against electromagnetic interference and ground loops.

• Non-Mechanical Switching: Utilizes robust solid-state technology for AC switching, offering a longer operational life compared to traditional relay contacts.

• S800 Hot-Swap Performance: Engineered for high-availability systems, the module can be safely replaced under power without interrupting the I/O station.

• Industrial Diagnostics: Integrated front-panel LED indicators provide real-time status updates for each channel's state and general hardware health.

• Enhanced System Safety: Built to rigorous industrial standards to protect the low-voltage control logic from high-voltage field-side transients.
