UNIT SSR

SKU:U122

Description

UNIT SSR Solid-state relays are different from traditional electromagnetic relays in that their switching life are much longer than that of electromagnetic relays. With integrated MOC3043M optocoupler isolation and zero-crossing detection,It supports input 3.3-5V DC control signal, and control output single-phase 220-250V AC power.

UNIT SSR are controlled by power semiconductor devices, with microsecond on/off speed and built-in overcurrent protection. Extensively used in lighting control, CNC machine tools, etc., where frequent on/off lines and fast response are required.

Note:
1. Please be careful when using high voltage AC loads, and do not operate with electricity.
2. This relay is for AC loads only.

Product Features

  • Over-zero type SSR
  • Built-in over-current protection
  • Built-in opto-coupler isolation, with over-zero detection
  • High speed, Low noise, Durable, high reliability, high sensitivity
  • More convenient to access with GROVE interface
  • Supports UIFlow graphic programming, realizing the relay remote control with M5 controller in just 3 mins!

Advantages over mechanical relays:
1.Faster on/off speed and no physical contact wear.
2.Completely silent operation.
3. No electrical sparks for use in complex environments.
4.Long lasting
5 .Compact size

Feature Introduction

Control the relay to switch on and off

The control signals of SSR UNIT and RELAY UNIT are the same, and RELAY Block can be used directly for control in UIFlow.

  • set COM connect ON Control relay closure

  • set COM connect OFF Control relay disconnect

Usage

Arduino

#include <M5Stack.h>

void setup() {
  M5.begin();
  M5.Power.begin();
  M5.Lcd.clear(BLACK);
  M5.Lcd.setTextFont(4);
  M5.Lcd.setTextColor(YELLOW, BLACK);
  M5.Lcd.setCursor(50, 0, 4);
  M5.Lcd.println(("SSR Example"));
  //disable the speak noise
  dacWrite(25, 0);
  pinMode(26, OUTPUT);
}

void loop(void) {
  digitalWrite(26, HIGH);
  delay(500);
  digitalWrite(26, LOW);
  delay(500);
}
