4 Channel 5V Relay Module

4-fach 5V Relais Modul mit Optokopplern, Original Songle Relais. Masse Versorgungsspannung (GND) und Masse der Optokoppler (COM) lässt sich per Jumper aufttrennen (völlige galvanische Trennung vom Eingang)   Schaltzustand wird per LED angezeigt, 

Description

This Relay employs high quality relay with four channels input and four channels output. It can be connected to 250V/10A AC element or 24V/10A DC element to the maximum, therefore, it can be used to control lights, motors and etc.

The modularized design makes it easy to connect to Arduino expansion board. The output state of the relay is shown by a luminous diode for the convenience of application.
