“Single Channel Large current relay board with dual DC-DC converter board is mainly designed for Hobby CNC, Routers, and Plasma cutters. Hobby CNC controller requires multiple DC outputs to drive various things. This board provides 5V DC and 12V DC 1Amp each. The dual supply helps driving LPT breakout board, Sensors, Limit switches and few other things that require 5V and 12V. The Relay has large current handle capacity and can be used to drive spindles, solenoids, and other things that require switching. The relay requires TTL High signal to trigger or it has the capability to even trigger with GND signal.”
