WCS2702 Adjustable Current Sense Module 2A DC5V with Overcurrent Protection and LED Indicator

Two main functions Analog signal path for A/D conversion The module provides an analog signal followed by an opamp stage, making it suitable for A/D conversion. Switch signal with programmable current limit The switch signal is preset to a current limit value. When the actual current reaches the preset value, the switch output changes from low level to level, and an LED indicator signals the event. Simple and easy to use. Key benefits Dual output for both precise measurement and digital signaling Analog output enables accurate current monitoring via an A/D converter. Switch output provides a clear, programmable threshold alert. Programmable current limit Allows automatic protection and control actions when current reaches the preset threshold. Visual indication LED indicator provides immediate status without software. Easy integration with A/D based systems Designed to fit into existing measurement and control architectures that use ADC inputs. Applications AC and DC current detection Motor stall detection Leakage detection Multichannel current detection Use scenarios Realtime monitoring with an MCU Connect the analog output to an MCU ADC for continuous current measurement; use the switch output to trigger an alert or protective action when the limit is reached. Motor protection in drive systems Monitor motor current; when stall current is detected, the switch output goes and the LED lights, enabling safe shutdown or fault indication, while the analog output can be used for diagnostic control loops. Multichannel current monitoring Deploy multiple modules to monitor several current paths simultaneously; use analog outputs for detailed data and switch outputs for independent threshold signaling across channels.
