High/Low Selectable Input Trigger

This relay card takes up little space but includes all the essential jumpers for high or low input trigger selection. This will save you the headache of replacing the circuit and will cost you a bit more. Small screw terminals are something between brands. They are undersized for the wire size that will fit compared to the amperage rating of the relay.
