8A Reverse Polarity Switch Module
This is a compact reverse polarity switch module and can be used to change the polarity of the output terminals 5 and 6. Most common uses are to change the direction of a DC Motor.
Once the control voltage (Terminals 1 and 2) have power supplied to them the relay is activated and the output terminals of 5 and 6 will then change polarity.
The terminals 3 and 4 are the input voltage for the module and can take a max 8A 240VAC, the output voltage is fed from this input voltage The output will always have an active state, if the relay is off this will be the same polarity as the input voltage and when the relay is on the polarity will be the reverse of the input voltage.
Please note that PCB Pillars / Standoffs will be required for the circuit board. These fit into the 4 pre drilled holes of the circuit board. We have varies types available in our store PCB Pillars / Standoffs
