Description This is a single channel 12V relay module. This has single 12V DC relay. The maximum current ratting for the contacts of this relay is 10 A. Thus, any load that withstands maximum current of 10 A can be connected to this relay module. This is an active low relay module as the relay works when an active low signal is applied on its signal input. The switching is done by the BC557 NPN transistor. The relay of the circuit uses the current supply for opening or closing switch contacts. The overall circuit works when an active low signal is applied on the SIG pin of the PCB. This PCB has three inputs which are VCC, GND and SIG. Input control signal can be applied through any controller boards like Arduino, Node MCU etc. This PCB has three outputs which are NC, Common and NO. These pins are output of the Relay. Any AC or DC load can be connected to these outputs. This PCB has two LEDs, one is red and another is green. If the board receives power, then red LED is on and if the relay is activated then the green LED is on. Application: – Used in over voltage/under voltage protection system Mains Switching Speed control of motors through start-delta converters Automatic control electrical appliances Electrical isolation in between high & low power sources AC voltage load switching using less voltage DC Delivery of Isolated power Switching with High Current Quantity-wise price list: Quantity price above>10 40 Note: Prices mentioned in the above list are without GST and only applicable for manual orders by phone or WhatsApp. Details of this product can be found in the following link Active Low Relay Module Circuit – Addauto Technology Private Limited Manual of 12V-10A ACTIVE LOW 1-CHANNEL RELAY BOARD MODULE Share this post: on Twitter on Facebook on LinkedIn Related
