Obviously I love the opto-isolation of the input section and the automatic inversion of trigger signals set by the jumper blocks, but the downside is that if I’m building something that relies upon the trigger line having the same resistance of the relay coil, that’s not going to happen. regardless of it being powered at 12V, the inputs tend to make the relays trigger around 1.4v and release around 1.2v, so creating an RC delay circuit to delay the opening or closing of the relays would be impossible. But, the use case for this are for microcontroller hackers to be able to drive the relays from their MCU GPIO pins, and the good news is that regardless of the voltage input to the board or the relay voltage value, you can still trigger the relays with any logic level from 3v3 up to the rated voltage of the board.
