The second function is the switch signal, which can pre-set the current limit value. When the actual current value is the pre-set current value, the switch signal change from low level to high level, and there be an LED indicator to indicate. Simple and easy to use. This module has two main functions. The first function is the analog signal followed by the op amp, which is suitable for A/D conversion. Application areas: AC and DC current detection; motor stall detection; leakage detection; multi-channel current detection. Application: Intelligent car motor overcurrent detection, stall protection current detection, short circuit protection testing, demonstration teaching experiments and other occasions to facilitate the secondary development., Weight: 0.02425084882 pounds, Manufacturer: Kueohse
