## Description

desertcart.com: ANMBEST 2PCS 5V 4 Channel Relay with Optocoupler High/Low Level Trigger | Module for Arduino,Industrial use, stable performance, wide compatibility : Electronics

Review: Just works! - Great 4 channel relay module for Arduino & Raspberry Pi. Includes a 5V in and ground screw terminal pair (marked as DC+ and DC-, respectively), along with four inputs for each channel. The relays all have optocouplers, transistors, flyback diodes, and LED indicators, so you don’t need to worry about adding those yourself. The opposite side of the board has Normally Closed, Common, and Normally Open connectors (marked as NC, COM, and NO respectively) for each relay.
Review: Compact board that flips the relays reliably and cheaply! - Reliably switching 24v sprinkler solenoid valves for over a year. Good price! Got a backup... It's in an outdoor enclosure so I don't care about the noise (yes, it's a mechanical relay) or the LED (nice visual feedback). Easy to integrate with an Arduino and I think it'll do just fine. The system doesn’t stay out in the winter but it's there during the 100°+ heat. I have not experienced any negative issues with the Arduino and I assume it's optically isolated to the controller/signal.

## 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.

### ⭐⭐⭐⭐ Pretty alright
*by E***0 on July 1, 2026*

Good overall but not for constant higher loads. The relay breaks down internally and starts to get stuck. Each relay is rated for max 10A and the most I had on one was 8A. So I guess a constant load of 8A is still to much for this board. Overall good and simple design. Still recommend.
