RM-4-12V, 4 Channel 12V Relay Module
This 4 Channel Relay Module (with light coupling) 12V module meets the safety standard, as control areas and load area have the isolation groove. Also, it allows for optical coupling isolation module.
The 4 Channel Relay Module is reliable & more stable when it is triggered. This product consists of double FR-4 circuit board design and high end SMT process. It possesses power operation and relay operation instructions. Relay terminals (C (Closed), NC (Normally-closed), NO (Normally-open)) are accessible through screw terminals which makes wiring to the board very simple.
The inputs of 4 Channel 12V Relay Module are isolated to protect any control circuitry.
A wide range of microcontrollers such as Arduino, AVR, PIC and ARM can control it.
The use of such high-voltage relay eliminates the risk of heating up the relay as electromechanical relay limit the current consumption in accordance with voltage rating.
