4-Channel Relay Board (KIT62S)

This 4-channel relay board can be controlled by feeding 2 to 5 V TTL from Micro-controller Development Boards, Remote Receivers, or any other circuit which required isolated high current and high voltage switching by applying TTL voltage. LED indication for Relay On/Off, Relay Output normally open and normally close via screw terminal for easy connection. Clamp diodes for current limiting for self protections. Input via berg connector. Board can control AC or DC load.
