Description: WCS2720 DC 30A current detection sensor overcurrent / short circuit protection detection module. Has a signal output indicator. Wide current detection range DC: 0-30A Output overcurrent relays normally open and normally closed output. Over-current signal is set to a full range of adjustable. With mounting holes for easy installation of firmware. Converting analog signals sampled current output, which can be accessed ADC, TTL-level signal output can be connected to the microcontroller IO port control. In addition to the module above the threshold adjustment potentiometer outside the other two potentiometers prohibit transfers. Applications: Smart car motor overcurrent detection, stall protection current detection, short circuit protection testing, demonstration teaching experiments and so on, to facilitate the secondary development. Specification: Working voltage: DC 12V Output: relay output; Analog output (0-5V linear output corresponding to 0-30A); Size: approx. 72 x 45 x 18mm Package Includes:(2 Pack) 1 Piece DC Current Sensor Detection Module
