Standard TTL Level logic controlled (AVR, Arduino, 8051, PIC, ARM). Hello, I bought this 12V one 1 Channel Relay Module With optocoupler by mistake. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal. You can ask us (by Email Only ) to change the items on your order, update an address or payment method, or just cancel it. The circuit shown in figure 1 will drive the relay through optocoupler in same circuit with same power supply. The module is compliant with international safety standards, control and load areas isolation trenches. Each one needs 15mA - 20mA driver current and Equipped with high current relay: DC 5V / 10A, AC 250V / 10A. You may track the shipping status of your order on our website, by clicking at Track your Order section. The comparator output directly drives the relay to connect 220V AC or other equipment. This neat relay module features 4 x 5V relays rated at 10A/250V each. Use them in any sector of industry including process technology and power engineering, railway applications and machine engineering, as well as general control cabinet construction. Add to Wishlist. Each relay can individually switch on/off by an opto-isolated digital input, which that can connect directly to a microcontroller output pin. Mechanical Relay. Compare. We will estimate the damages then decide the best way to exchange or return the product. Sri Raghavendra Nagar Shop #1, PK Complex 4 way electromagnetic relay module low level trigger without optocoupler with light 3.3v/5v/12v/24v. Application code: Green indicates that the  relay is closed, the red disconnect, Can detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighters distance of 80cm, the larger the flame, the greater the distance test, The detection angle of 60 degrees, the flame spectrum particularly sensitive, The module can be set high level or low-level trigger by the jumper, One normally closed contact and one normally open contact, Pull-down circuit for avoidance of malfunction, Power supply indicator and Control indicator lamp. You agree to pay for the return shipping on exchanges and returns and we will reimburse this cost upon verification of a defect with the product. They'll do so without regard to the coil voltage. However, we will inform you before doing it. 126/128/129/2500 PCB Green Power Connectors. All returns must include a copy of the original packing list that came with your shipment. the transistor inside the optocoupler will destroy from relay side , so the main resean , is total separation of gnd , power lines. Its three terminals are NC, NO, COM. • Optocoupler Board 7112 • Relay Board 7121 1.1 Optocoupler Board 7112 The board 7112 has 24 optocoupler exits where potential free signals/pulses can be put out. Description ; Reviews (0) Description. Due to the nature of the products we are selling and our strict quality policy, we are unable to offer order cancellation and return without a valid reason. If you'd care to post links to the datasheets for the relay you have and the optocoupler you're considering, as well as a schematic or other reasonable description of your load (at a minimum: operating voltage, operating current, inrush current, inductive discharge at shutdown), I'd be happy to take a look.
