Model 8112 from the SeaDAC Lite series enables robust USB I/O interfacing, combining input isolation and power switching in a compact form factor. The isolated inputs offer enhanced protection against surges, while the Form C relays allow flexible control of high-current loads in either normally open or normally closed configurations.

It uses 3.5mm removable terminal blocks for simplified field wiring and includes a USB Type B SeaLATCH locking connector that prevents accidental disconnection. The enclosure is durable enough for industrial environments, and installation is seamless with Sealevel’s SeaMAX software suite, which provides GUI and API-based control across platforms.

This unit is perfect for engineers needing reliable I/O control in automation, test benches, equipment triggering, and more.
