Two main functions - Analog signal output with an operational amplifier for A/D conversion. The analog signal is produced and conditioned by an op-amp to facilitate accurate A/D conversion. - Switching signal for preset current limit. When the actual current value exceeds the preset limit, the switching output changes from low to high, and the LED indicator signals this condition. Key benefits - Clear, reliable analog signal path for precise data acquisition and A/D processing. - Real-time overcurrent indication via a dedicated switching output. - Immediate visual feedback with an LED indicator during overlimit events. - Easy integration with data acquisition, microcontroller, and control systems for monitoring and automation. - Simple protection mechanism by signaling overcurrent without complex external circuitry. 2-3 practical use scenarios - Bench data acquisition: connect to a microcontroller or DAQ to monitor analog signals and receive a digital alert when current exceeds the set limit. - Power supply or electronic load monitoring: use the switching output to flag overcurrent conditions and trigger protective or logging actions. - Motor drive or inverter control: monitor current in real-time and obtain a clear indication when the current surpasses the preset threshold for safety and control purposes.
