HAWK 4×4-20 mA 1 I/O Card

The Hawk 4 × 4–20 mA I/O Card is a dedicated expansion card for the Hawk platform, providing four independent 4–20 mA inputs for connecting industrial sensors that use current-loop signalling. This makes it particularly useful for integrating sensors that measure parameters such as pressure, temperature, moisture, vibration, tank levels, and other industrial variables.

Each channel provides dedicated positive and negative connections, while the card also includes a switched 5 V or 12 V power output for compatible sensors. With 12-bit measurement resolution, a 0–22 mA full-scale range, and typical accuracy of around 2%, the card provides a straightforward way to bring multiple 4–20 mA sensors into a single Hawk data-logging system.
