ELHLS/EXRL-HLS eDAQ-lite Simultaneous High Level Layer

ELHLS/EXRL-HLS eDAQ-lite Simultaneous High Level Layer

The Somat eDAQlite Simultaneous High Level Layer (ELHLS) offers four simultaneously sampled high-level differential analog inputs through independent connectors. Up to eight ELHLS layers can be added to a single eDAQlite system, enabling up to 32 channels. Networking multiple eDAQs make synchronous ELHLS channel counts virtually limitless.

The ELHLS can inherently handle any analog input from +/- 80V, and together with the Somat SMART conditioning modules, is a real multipurpose layer. Practically any input—thermocouples, strain gauges, accelerometers, microphones, or amplified and unamplified transducers—can be utilized with this layer. Software-selectable sample rates, transducer power, and digital filtering simplify the set-up of any channel. There are also several calibration options, including defined value, external, and multipoint, as well as shunt calibrations with embedded software tools offered with the Strain SMART Module.
