  • Maximum Load: AC 250V/10A, DC 30V/10A

Description:

This is a High and Low Level (user configurable) 5V 1-channel relay interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliances and equipment with a large current. It is equipped with high-current relays that work under AC250V 10A or DC30V 10A. It has a standard interface that can be controlled directly by the microcontroller. This module is optically isolated from the high voltage side for safety requirement and also prevent ground loop when interfacing with the microcontroller.

Specifications:

  • Operating Voltage (power): 5V
  • Trigger Voltage: 3.3V to 5V
  • Trigger Current: 5mA
  • Maximum Load: AC 250V/10A, DC 30V/10A

Features:

  • Normally open and normally closed.
  • High-level trigger or low-level trigger selection by a jumper.
  • Optocoupler isolation.
  • Terminal blocks for both input and output.
  • Two LED indicators: power (green LED), the relay status (red LED).
  • Fault-tolerant design, even if the control line is broken, the relay will not operate.

Input Terminals:

  • DC+: Connect the positive pole of the 5V power supply.
  • DC-: Connected the negative pole of the 5V power supply.
  • IN: Signal trigger input (3.3V to 5V, high or low-level signal selected via a jumper).

Output Terminals:

  • NO: The normally open interface.
  • NC: The normally closed interface.
  • COM: The common interface for both normally open and normally closed.

High/low-level Trigger Jumper:

  • If the jumper is placed between COM and L, the relay uses a LOW-level trigger.
  • If the jumper is placed between COM and H, the relay uses a HIGH-level trigger.

How it Works:

  • High-Level Trigger:
    • When IN is a LOW-level signal, the NO does not connect with COM and the NC connects with COM.
    • When IN is a HIGH-level signal, the NO connects with COM and the NC does not connect with COM.
  • Low-Level Trigger:
    • When IN is a LOW-level signal, the NO connects with COM and the NC does not connect with COM.
    • When IN is a HIGH-level signal, the NO does not connect with COM and the NC connects with COM.
