Description:   The module uses genuine quality relay, normally open interfaces Using SMD optocoupler isolation, driving ability, stable performance The module can be high or low by a jumper setting trigger Fault-tolerant design, even if the control line is broken, the relay will not operate The power indicator (green), the relay status indicator (red) The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient   Specification:   Maximum load: AC 250V/10A, DC 30V/10A Trigger current: 5mA Working voltage: 12V Module size: 73 x 50 x 18.5mm (L x W x H) Four mounting bolts holes, diameter 3.1mm   Module Interface:   DC+: positive power supply (VCC) DC-: negative power supply (GND) IN: can be high or low level control relay   Relay Outputs:   NO: normally open relay interface COM: Common Interface Relays NC: normally closed relay interface   High and low level trigger options:   It is low level trigger when jumper connect to LOW pin It is high level trigger when jumper connect to HIGH pin   Package included:   5 x 4 Channel H/L Level Trigger Optocoupler Relay Module

Feature: The water-level sensor is used to indicate the level of water in an overhead tank, by using this we can avoid the overflow of water, and at any time we can know the level of water in a tank, it has a simple circuit. Package includes: 5 x Water-level sensor

5Pcs Speed Measuring Sensor Counter Motor Test Groove Coupler Module For Arduino Application: Widely used in motor speed detection, pulse count, the position limit, etc.   Feature:   Using imported groove optical coupling sensor, width 5mm. It have the output state light, if output high level, the lights are off. if output low level,it on. If it covered,it will output high level;otherwise it output low level. Good signal and waveform, with strong driving ability for more than 15mA. The working voltage of 3.3V to 5V. Output: digital switch output (0 and 1). Equipped with a fixed bolt hole, easily install. Small board PCB size: 3.2 cm x 1.4 cm. Use the LM393 wide voltage comparer.   Specification:   The DO output interface can be directly connected to a micro-controller IO port, if there is a block detection sensor, such as the speed of the motor encoder can detect. DO modules can be connected to the relay, limit switch, and other functions, it can also with the active buzzer module, compose alarm.   Wiring specification: VCC Connect the positive 3.3 5 v power supply GND Connect power negative DO TTL switch signal output AO This module does not work Package included: 5 x Speed Measuring Sensor Module

5Pcs A87 4 Channel Optocoupler Isolation Module High And Low Level Expansion Board For Arduino Description:1. Function: Use the low level to control the high level. Such as the use of single-chip 3V or 5V voltage control 9V or 12v voltage.2. HVCC should not exceed 24V. Output OUT1 / OUT2 / OUT3 / OUT4 output current equal to HVCC / 5.1K, absorption current 500ma.3. This module uses TLP281 chip (for Toshiba).4. Schematic:Input and output instructions: Input: IN1 / IN2 / IN3 / IN4, then the microcontroller or Arduino IO port, GND and the Arduino development board connected to the GND.IN1 / IN2 / IN3 / IN4 controls OUT1 / OUT2 / OUT3 / OUT4, respectively.Output: OUT1 / OUT2 / OUT3 / OUT4Output: HVCC: Connect the controlled high voltage positive, HGND connected to the controlled high voltage negativeUse: When IN1 is high, the corresponding OUT1 voltage is equal to HVCC, when IN1 is low, the OUT1 voltage is equal to HGNDUse examples The following example shows how to use the microcontroller's IO port to control the 24V motor rotation. Figure motor operating voltage of 24V,red ' ' that the motor power positive, black '-' that the motor power supply negative. When the microcontroller IO_0 output high, the motor rotate,when the IO_0 port output low, the motor stops rotating.Package included:5 x A87 4 Channel Optocoupler Isolation Module
