Relay Board Maximum Load: AC 250V/10A; DC 30V/10A With Power and Relay Action Indicator;Trigger Current: 5mA
Jumper Design: The Relay Module has a Jumper That You Can Set Rather the Unit State Changes with High or Low Signal. Has Screw Terminals for Relay (NC,C,NO) and for Input; Coil +, Coil - and Trigger.
Optocoupler Isolation:1 Channel Relay Board use Optocoupler Isolation that has Strong Driving Ability and Stable Performance ,The Isolation Circuit Prevent Damages to I / O Port by Relay Switch Current
Fault Tolerant Design, Even if the Control Line is Broken, the Relay will not Operate;All Interfaces of Relay can be Wired Out Through the Terminals Directly,Normally Open and Normally Closed
Easy to Install:Equipped with a Terminal Block and Fixed Bolt Holes on Both Sides (Diameter: 3.1mm), the Interface can be connected through the terminal block directly Wide Application:Standard Interface can be Connected with Microcontrollers Directly ,The Relay Module Can be Used to Control Various Loads, such as Electromagnetic Relays, LED Lights,Drivers, Motors, Electric Motors, Straws, etc.
