DIGITAL MATTER Hawk Quad 4-20mA kaart met Vboost

Industrial automation engineers and IoT integrators rely on precise sensor data for process control and remote monitoring. The DIGITAL MATTER Hawk Quad 4-20mA Card with Vboost adds four isolated 4-20mA current loop inputs to compatible Hawk Series gateways, enabling direct connection of industrial transmitters, flow meters, pressure sensors, and level probes. With integrated Vboost technology, it supplies regulated excitation voltage to loop-powered sensors, eliminating the need for external power supplies in many installations. The card converts analog signals to digital values with 12-bit resolution, ensuring accurate data capture for SCADA, asset tracking, and condition monitoring systems.

Key specifications

• 4 independent 4-20mA current loop input channels
• Integrated Vboost sensor power supply (voltage boost)
• 12-bit ADC resolution for high measurement accuracy
• Galvanic isolation between channels and host gateway
• Operating temperature range: -30°C to +70°C
• Powered directly by the host Hawk gateway
• Internal slot mounting for seamless integration

Why choose it

This expansion module simplifies industrial sensor integration by providing a compact, reliable interface that leverages the Hawk gateway's processing and connectivity. The Vboost feature powers loop sensors directly, reducing wiring complexity and component count. Galvanic isolation protects the gateway from ground loops and transient voltages, enhancing system reliability in harsh environments. With wide temperature tolerance and low power draw from the host, it is suitable for remote and unattended installations.

Ideal use cases

• Remote monitoring of tank levels, pressure, and flow in utilities and oil & gas
• Industrial process control with legacy 4-20mA sensors
• Environmental monitoring stations requiring multiple analog inputs
• Condition monitoring of pumps, motors, and machinery
• SCADA and telemetry systems using Digital Matter Hawk gateways

Good to know

The card installs into an internal slot of compatible Hawk gateways; no external enclosure or additional power supply is needed. It is designed for use with loop-powered sensors that accept supply voltages up to the Vboost output. Always verify sensor compatibility and wiring polarity before commissioning.
