4 Channel 12V Relay Module Solid State High Level SSR DC Control 250V 2A with Resistive

This is 4 Channel 12V Solid State Relay Module. A solid-state relay (SSR) is just what it sounds like; an IC that acts like a mechanical relay. They allow you to control high-voltage AC loads from lower voltage DC control circuitry. They accomplish this by using infrared light as the contact, a solid-state relay is really just an IR LED and a photo Triac sealed up into a little box. Solid-state relays have several advantages over mechanical relays. A Solid State Relay is similar to a mechanic relay where it can be controlled through a digital signal. Solid State Relay generates no noise and has a much longer lifespan compared to the traditional mechanic relay. 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 relay scan 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) Features: 4-channel 2 AMP Solid State Relay board. Control 4 loads of up to 2 amps each at 240 V AC. Good for lighting, Holiday displays, etc. Has been assembled, and the electrical test passed. Led indicator for each relay. Use it to control various appliances and other equipment with a large current. It can be controlled directly by a Microcontroller Input control signal voltage. 0-0.5V low stage SSR is OFF 0.5V 2.5V (unknown state). 2.5-20V high stage SSR is ON Specifications: Part Number: G3MB-202P Power supply:5VDC/160mA Trigger Voltage (VDC):12 Switching Voltage (VAC):240@2A Isolation: Phototriac Zero Cross: Yes Length (mm):57 Width (mm):57 Height (mm):24 Weight (gm):35 Package Includes: 1 x 4 Channel 12V Relay Module Solid State High-Level SSR DC Control 250V 2A with Resistive Fuse
