Features: 1. Made of high quality material, durable and long service life. 2. The maximum drive current is 8A and the standby current is less than 0.11-1mA 3. Low standby power consumption and high output power 4. This is trigger switch board which once triggered, the output terminal outputs the power supply voltage and triggers the output terminal without voltage output again. 5. Generally used in self-locking electronic switches, development boards, motors, relays, solenoid valves, etc. Specification: Condition: 100% Brand New Power Supply Voltage: DC 9-24V (H9-24V version) Standby current: less than 0.11-1mA The driver IC is an N-channel MOSFET AOD4184 with a maximum drive current of 8A. Allow continuous output current: H9-24V version: 8A (9V-15V); 6A (15V-24V) Size: Approx. 36 * 17.5 * 14mm / 1.4 * 0.7 * 0.6in Weight: Approx. 7g / 0.2oz Package List: 1 * Trigger Switch Board Pin Description: Vi +: power input + Vi-: power input - Vo +: power output + Vo-: Power Output - G: trigger signal input ground T: trigger signal input terminal (0.2-2 second low pulse trigger) Note: Inductive load, load in parallel with appropriate freewheeling diodes to avoid damaging the switching elements of the circuit
