Key features

  • It is 4 Channel Isolated 5V 10A Relay Module, each relay can individually switch on/off by an opto-isolated digital input, Standard interface can be directly connected with microcontrollers and be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, DSP, etc., very convenient.
  • Equipped with high-current relay, maximum load: AC250V 10A, 15A 125VAC, DC30V 10A; Trigger current of opto-isolator: 5mA.
  • RELIABLE: Fault-tolerant design, even if the control line breaks, the relay will not move; With optical coupling isolation, triggering more reliable, more stable.
  • EASY to INSTALL: Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation.
  • High/Low level trigger can be selected by jumper. Very versatile, you can reverse the input logic with the jumper.

Free shipping included. 30-day hassle-free returns.
