Product Details:

A relay is an electrically operated device. It has a control system and (also called input circuit or input contactor) and controlled system (also called output circuit or output cont actor). It is frequently used in automatic control circuit. To put it simply, it is an automatic switch to controlling a high-current circuit with a low-current signal.

Features:

The features of 1-Channel Relay module are as follow:

• Good in safety. In power system and high voltage system, the lower current can control the higher one.
• 1-channel high voltage system output, meeting the needs of single channel control
• Wide range of controllable voltage.
• Being able to control high load current, which can reach 240V, 10A
• With a normally-open (NO) contact and a normally-closed (NC) contacts

INTRODUCTION This is a small and easy to use 4 channel opto-isolated relay board that operates on 12V. Use it to control one 240V power appliance directly from microcontrollers or low voltage circuits. The board uses a high quality relay, which can handle a maximum of 7A/240 V AC or 7A/24V DC. Each relay has all three connections - Common, Normally Open, Normally Closed brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication and a relay status LED to ease debugging. The board can accept inputs within a wide range of voltages from 4V to 12V. Power input and relay control signals are brought to header pins on the board. Hence, the board can be easily interfaced with our development boards using our female to female jumper wiresA relay is an electrical switch that opens and closes under the control of another electrical circuit. In the original form, the switch is operated by an electromagnet to open or close one or many sets of contacts. Because a relay is able to control an output circuit of higher power than the input circuit, it can be considered to be, in a broad sense, form of an electrical amplifier.1. Normally - open (NO) contacts connect the circuit when the relay is activate; the circuit is disconnected when the relay is inactive. It is also called a FORM A contact or “make” contact.2. Normally - closed (NC) contacts disconnect the circuit when the relay is activated; the circuit is connected when relay is inactive. It is also called FORM B contact or” break” contact.3. Change-over or double-throw contacts control two circuits; one normally open contact and one normally –closed contact with a common terminal. It is also called a Form C “transfer “contact.

FEATURES
• 4 Relay Output Operation Voltage: 12V DC• Optically isolated Output• Very less current consumption.• In-built surge protection circuit for AC peripherals.• Relay ON and Power On indication LEDs• Onboard 4 mounting holes for easy mounting• Header pins are provided for inputs, which enable easy connections to• Microcontroller boards, external circuits, etc.

A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits, repeating the signal coming in from one circuit and re-transmitting it to another. Relays were used extensively in telephone exchanges and early computers to perform logical operations.
