ITEM NAME:Sw-520 Tilt Sensor Relay Module 12V Device Tilt Dump Protection Alarm Trigg H7K4 Sw-520 Tilt Sensor Relay Module 12V Device Tilt Dump Protection Alarm Trigg H7K4 Module Features:1, the sensor default The company's highly sensitive SW-520D angle sensor, with different angle sensors can achieve different functions, a 45 degree angle sensor, 90 degree angle sensor, optional any angle sensor 2, the comparator output direct drive relay, can be accessed 220V AC or other equipment; 3, with the potentiometer to adjust the sensitivity; 4, with 4 3mm fixed bolt holes, easy to install 5, the output with blue terminal block, easy wiring Theory: Voltage Relay Contact Load: Low Power Usage: General Purpose use:Various angle sensors, dumping sensor tilt sensor, output with relay, direct access to large current load, can be applied to a variety of equipment dumping protection, home appliances dumping protection. Module Instructions: 1. The initial state of the relay depends on the opening and closing of the tilt sensor. When the relay is switched on, the relay is connected and the common terminal is connected to the normally open end. When the tilt sensor is disconnected, the relay is disconnected, End connected 2. Tilt sensors are generally installed in the initial state of the normally open state, so that the tilt sensor and the relay is not in working.The default SW-520D sensor is used for 90 degree dump detection. The initial state of the relay depends on the opening and closing of the tilt sensor. When the tilt sensor is disconnected, the relay is disconnected, End connected.
