1-Channel Solid State Relay Module

Solid State Relay Module for Effortless AC Load Control

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 phototriac sealed up into a little box.

Solid state relays, 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’s no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.

Features:

• Size: 25*34*25 (L*W*H)

• Input voltage: 5VDC

• Maximum Output Current: 2A

• Maximum Output Voltage: 240VAC

• Input Voltage of Control Signal: 0-2.5V (low level state), the relay will be on; 3-5V (high level state), the relay will be off.

• Triggered at low level.
