DCSSR

DCSSR - DC Solid State Relay

DCSSR are used to switch medium/high current DC loads such as high power LEDS, Dumb RGB Strips, DC Floodlights, solenoids, etc. They allow the high current switching element to be electrically isolated from the input computer signal driving the channel for safety. They are generally driven by a computer or a controller hooked to a computer to provide the signaling to turn the DCSSR channels on and off. They are generally connected to to the controller using low power 5VDC signaling. Their outputs are connected to N-Channel MOSFETs that act as switches. The power for the DC load is connected directly to the DCSSR and is switched by the MOSFETs and the power is available on the output terminal strips.
