The sensor output wouldnt have the power to drive anything substantial so I added the relays to allow uprating the switching ability of the sensor. The driven beacon has 2 lights and a buzzer. This relay could drive upto 230v 10AMPs so could be used to stop and start a hoover with a current sensor etc to get automatic stop start of a hoover with 230v power tools etc. The ideas are endless. I use the 2 relays to seperate the light control and buzzer control for my little project. Review: Good product - A good little relay that easy fits in a single gang surface box. ## Features - 2 Channel Relay Module Voltage : 24V; Normally Open Interfaces Maximum Load : AC 250V/10A, DC 30V/10A - 2 Channel Relay Module 24V Comes with High-Current Relay,Trigger Current : 5mA - 24V Relay Module is 2 Channel Isolated, Each Relay Can Individually Switch On/Off by An Opto-Isolated Digital Input - Relay Module Designed With Fault-Tolerant , Even If The Control Line Breaks, The Relay Will Not Move; With Optical Coupling Isolation,Triggering More Reliable and Stable - 2 Channel Module Equipped With Screwed Terminal Plate and Fixed Bolt Holes,Standard Interface Can Connect With Microcontrollers and be Controlled by a Wide Range of Microcontrollers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B99YFF9Z | | Best Sellers Rank | 10,997 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 6 in Electromechanical Relays | | Brand | AEDIKO | | Coil Voltage | 24 Volts (DC) | | Connector Type | Screw | | Connector type | Screw | | Contact Current Rating | 10 Amps | | Contact Material | Silver | | Contact Type | Normally Open | | Contact material | Silver | | Contact type | Normally Open | | Country Of Origin | China | | Current Rating | 10 Amps | | Current rating | 10 Amps | | Customer Reviews | 4.8 out of 5 stars 9 Reviews | | Manufacturer | AEDIKO | | Manufacturer Part Number | 19534EU | | Minimum Switching Voltage | 24 Volts (DC) | | Mounting Type | Bolt Mount | | Mounting type | Bolt Mount | | Operation Mode | Off | | UPC | 701715539495 | ## Product Details - **Connector type:** Screw - **Contact material:** Silver - **Contact type:** Normally Open - **Current rating:** 10 Amps - **Mounting type:** Bolt Mount ## Images ![2pcs DC 24V Relay Module 2 Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger - Image 1](https://m.media-amazon.com/images/I/71RvyLQkeML.jpg) ![2pcs DC 24V Relay Module 2 Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger - Image 2](https://m.media-amazon.com/images/I/71-Znl0El+L.jpg) ![2pcs DC 24V Relay Module 2 Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger - Image 3](https://m.media-amazon.com/images/I/71tugUsixEL.jpg) ![2pcs DC 24V Relay Module 2 Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger - Image 4](https://m.media-amazon.com/images/I/71ygAMCdrwL.jpg) ![2pcs DC 24V Relay Module 2 Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger - Image 5](https://m.media-amazon.com/images/I/71LuCkdkm5L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 2 channel relay for Dust Collector alarm. *by L***B on 28 August 2024* I used this product as an interface between a photoelectric sensor and an indicating beacon.
