5V Dual Channel Relay Module with Optocoupler


EGP35.00

Specification:

  • Low Level Trigger Relay Module
  • Two separate LEDs for On/Off indication of the Relay
  • Triggering input voltage 3.3V – 5V
  • Back EMF protection
  • 2 LEDs to indicate when relays are ON.
  • Works with logic level signals from 3.3V or 5V devices
  • Opto isolation circuitry
  • Module with diode current protection, short response time
  • AC Control Voltage: 250V @max.10A (recommended 5A)
  • DC Control Voltage: 30V @max. 10A (recommended 5A)

Module interface:

  • GND – Connect 0V to this pin.
  • IN1 – Controls relay 1, active Low Relay will turn on when this input goes below about 2.0V
  • IN2 – Controls relay 2, active Low Relay will turn on when this input goes below about 2.0V
  • VCC – Connect 5V to this pin. Is used to power the optocouplers

Note: This 5V Dual Channel Relay Module is for low level trigger only.

About high level and low level-triggered mode:

  1. High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered away.
  2. Low-level trigger refers to the signal voltage between the input terminal and Earth 0V trigger, can be understood as the signal input terminal and the GND negative electrode short circuit triggered away 1-channel relay module connection
  3. Jumper Instruction = The relay can be turned on when we connect 5v to one end and the other to -5v / Gnd, while talking about the jumper, if we short the VCC and the middle pin, then our relay will act as high level-triggered relay means that when we will apply + 5V input on its input pin it will be turned on and when the jumper will be set to “middle and GND”, it will act as a low-level triggered relay, It means that relay will be triggered when we implement the 5V / GND on its input pin.

Very good to use it with motor switching control or pump starting applications with your microcontrollers , arduino boards or PC port.
