5V 8 Channel SSR Module
5V 8 Channel SSR Module

5V 8 Channel SSR Module The 5V 8-Channel Solid-State Relay is somewhat similar to that of a mechanical relay & the difference is that there is no moving contact in a Solid-State Relay. Here we make use of a Phototrriac coupler to turn it ON and OFF. It finds its application in AC circuits as a TRIAC has got only limited applications in DC. The 5V 8 Channel SSR relay allows you to control high-voltage AC loads from lower voltage DC control circuitry. Solid-state relays do have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there are no moving contacts, solid-state relays can be switched much faster and for much longer periods without wearing out. Input Parts : DC+: connected to VCC (Supply power according to relay voltage) DC-: connected to GND IN1: CH1 Signal triggering the end of 1-channel relay module (active at the high level) IN2: CH2 Signal triggering the end of 2-channel relay module (active at the high level) IN3: CH3 Signal triggering the end of 3-channel relay module (active at the high level) IN4: CH4 Signal triggering the end of 4-channel relay module (active at the high level) IN5: CH5 Signal triggering the end of 5-channel relay module (active at the high level) IN6: CH6 Signal triggering the end of 6-channel relay module (active at the high level) IN7: CH7 Signal triggering the end of 7-channel relay module (active at the high level) IN8: CH8 Signal triggering the end of 8-channel relay module (active at the high level)

5mm White Led (Pack of 10) A  white light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white LED and illuminates blue light. When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy bandgap of the semiconductor.
