The SeaLink™ 24 Digital Module delivers high performance signal digitization, designed for demanding offshore operations. Engineered to integrate seamlessly with the SeaLink Recording System, this module provides exceptional data quality, robustness, and reliability for modern marine seismic applications.

High Performance Seismic Digitization
Each 24 channel module is powered through a 750 mA DC constant current loop, offering a compact, efficient architecture for large-scale marine seismic spreads. The analog front end supports sample rates from 0.125 ms to 4.0 ms using 24-bit delta-sigma converters, ensuring high-resolution subsurface imaging.

Digitized data—along with information from other modules—is transmitted via Seamap’s proprietary telemetry protocol using standard twisted pair cabling. All power, control, acquisition functions, and diagnostics are centrally managed through the SeaLink workstation on the survey vessel or platform.

Built for Harsh Marine Environments
Housed in a rugged 2.375” (60.325 mm) OD titanium enclosure, the SeaLink module withstands a crush depth of 6,925 m. Double O rings and nitrogen filling ensure long-term mechanical integrity and environmental protection.

The SeaLink 56 pin connector, custom engineered for extreme reliability, maintains secure connectivity across repeated deployments.

Flexible, Scalable, and Application Ready
The SeaLink 24-bit Data Acquisition System provides a scalable architecture that adapts to a wide range of offshore seismic operations, from ultra-high-resolution shallow work to deep-water reservoir monitoring. Seamap also offers custom module configurations for specialized project needs.

All external in sea metals are titanium, guaranteeing maximum corrosion resistance and lifecycle value.
