OMRON Solid State Relay Board 1 Channel

Rajguru Electronics proudly offers the OMRON 5V 240V solid-state relay rated at 2A with an output featuring a resistance-type fuse at 240V 2A. This versatile relay module is designed to provide precise control in various applications.

For activating the relay, the input control signal voltage requirements are as follows:
  1. When the signal voltage between 0-2.5V is applied (referred to as a low-level trigger), the relay is in the OFF state.
  2. When the signal voltage is between 3-5V (referred to as a high-level trigger), the relay is in the ON state.
In practical terms, a low-level trigger means that the signal voltage between the relay's input terminal and the negative terminal of the power supply is 0V or lower than the positive power supply voltage. This voltage level is low enough to trigger the relay and activate it. Typically, this involves connecting the negative terminal of the power supply to the relay's triggering terminal to achieve the trigger mode, which results in the relay being energized.
Additionally, the relay module comes equipped with a blue KF301 terminal that facilitates easy and secure connection to the control circuit. This ensures a reliable and efficient operation of the relay in your specific application.

QUICK OVERVIEW ; OMRON 1 Channel Solid State Relay Board 

  • Trigger voltage: 5VDC
  • Trigger current: 2mA
  • Switching Voltage: 240VAC@2A
  • Triggering: Low-level


It is an OMRON 5V 240V solid state relay 2A, output with resistance type fuse 240V 2A. The input control signal voltage for the relay module is: (the state of the 0-2.5V low-level relay OFF; the state of the 3-5V high-level relay ON). Low-level trigger refers to the signal triggering voltage between the end and the negative electrode of the power supply is OV, or trigger terminal voltage lower voltage than the positive power supply voltage, low to can trigger, make the relay, is usually the cathode of the power supply and the triggering end of a trigger mode connection, so that the relay is attracted. It has the blue KF301 terminal is connected to the line of control

Rajguru Electronics presents a 1 Channel 5V Solid State Relay Module, a cutting-edge electronic device that functions similarly to a traditional mechanical relay. This Solid State Relay (SSR) allows you to effectively control high-voltage AC loads using lower voltage DC control circuitry. It achieves this by utilizing infrared (IR) light as the 'contact,' encapsulating an IR LED and a photo Triac within a compact enclosure. Solid-state relays offer multiple advantages over their mechanical counterparts.
Our 1 Channel 5V Relay Module Solid State High-Level SSR DC Control 250V 2A with Resistive capability operates much like a mechanical relay but offers substantial benefits. It can be conveniently controlled via a digital signal, eliminating noise generation and significantly extending its operational lifespan compared to traditional mechanical relays.
Here's how it works: When you apply the input logic voltage to the coil, the Normally Closed (NC) contact will disconnect from the Common (COM), interrupting the electrical connection between them. Simultaneously, the Normally Open (NO) contact will establish a connection with the Common (COM), allowing electrical conductivity between them. Depending on your specific wiring configuration, this action will either turn on or off the connected load, offering precise control and reliability.
