DC MOTOR REVERSE POLARITY SWITCH DPDT RELAY MODULE 2A 12V

We also supply this unit in a 5v version

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 1A 125VAC/2A 30VDC, 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.

Control power supply 12v DC
Feed input 1-30v DC/1-125v AC
Output Voltage 1-30v DC 2A / 1-125V AC 1A (Depending on the feed input voltage)
DPDT Relay Module 30v DV 2A (up to a 60W motor)
125V AC 1A (up to 125W motor)
Board size 48mm x 30mm x 16mm
