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: 010V, 210V, 020mA, 420mA. By adjusting bias and gain parameters, it can be configured for other inputs within the 010V or 020mA range. 4. The default display mode shows percentage values. Users can customize the display range using settings F0-2 to F0-4. 5. Models equipped with RS485 interface support communication between meters, enabling easy multi-display setups. Model variants: - Standard version: HXDSBOXAH- - With RS485: HXDSBOXA-485 - With relay output: HXBOXAI-RL Power specifications: - Standard version and RS485 version: DC 625V, power consumption 24V/40mA - Relay output version: DC 825V, power consumption 24V/50mA Equipped with reverse polarity protection and surge protection.
