This module provides two core capabilities designed to support precise measurement and protected operation in compact form. Two core functions Analog signal path for A/D conversion: The input signal is conditioned through an opamp stage, making it suitable for reliable A/D conversion. This helps improve signal integrity, buffering, and impedance matching for accurate microcontroller or data acquisition input. Presettable currentlimit switch with status indication: The second function allows you to preset a current limit value. When the actual current reaches the preset value, the switch output transitions from low to and the LED indicator turns on to show the event. This enables proactive protection and clear visual feedback. Key benefits Accurate ADCready signal conditioning: The analog path with an opamp supports cleaner, more stable ADC measurements. Builtin current protection: A programmable current limit helps protect downstream circuits and loads, reducing the risk of damage from overcurrent. Clear status indication: The LED provides immediate, easytointerpret visual feedback of the overcurrent event. Simple integration: Two useful functions are provided in a single module, reducing parts count and saving board space. Robust status signaling: The defined switch transition from low to provides a straightforward digital signal for control logic or monitoring. Key attributes Function: combines an ADCready analog conditioning path with a presettable currentlimit switch and LED indicator. Compatibility: suitable for A/D conversion systems and microcontrollerbased control/monitoring applications. Size and form factor: compact form factor designed for easy integration on standard PCBs. Construction: designed for reliable operation in typical electronic assemblies and test environments. Performance: provides a stable analog conditioning path for accurate ADC input and a clear, fast switch response when the preset current is reached, with visual indication via the LED. Use scenarios Data acquisition systems: condition sensor signals for accurate ADC readings while monitoring current to protect the supply and sensors. Embedded control and protection: integrate into a microcontrollerbased board to provide a presettable overcurrent limit with a digital signal and LED status for quick diagnostics. Lab instrumentation and prototyping: use as a compact, dualfunction module to simplify test benches that require both analog conditioning for ADC inputs and currentlimiting protection with visible status. Notes The switch output remains low until the actual current equals the preset limit, at which point it transitions to and the LED indicates the event. This behavior supports straightforward integration with control logic and monitoring systems.
