1. The meter can be used as a universal analog input display device. It is compatible with various sensors that have analog output to display real-time physical measurements, such as temperature transmitters, frequency converters, motor speed, pressure, liquid level, concentration, and more. 2. The instrument supports both current input and voltage input. 3. Default input ranges: 0–10V, 2–10V, 0–20mA, 4–20mA. By adjusting the bias and gain parameters, it can be configured for other inputs within the 0–10V or 0–20mA range. 4. The default display mode is percentage. Users can customize the display range using settings F0-2 to F0-4. 5. Models equipped with an RS485 interface support communication between meters, enabling easy multi-point monitoring and display. Model variants: - Standard version: HXDSBOXAH- - With RS485: HXDSBOXA-485 - With relay output: HXBOXAI-RL Power specifications: - Standard version and RS485 version: DC 6–25V, power consumption 24V/40mA - Relay output version: DC 8–25V, power consumption 24V/50mA Equipped with reverse polarity protection and surge protection.
