Need some help please; I am new to the forum and possibly a little ignorant.
I need to use a relay to run a 12 DC actuator; the polarity needs to change to move it in and out of course.
My issue is the control for the actuator only provides a single input for the relay coils but reverses the polarity to drive a lower amp actuator directly using its built in relays.
So I need to energize the relays that drive the actuator based on the polarity applied to the coils.
12 vdc 15 amp load
Example using two relays
Relay 1 energizes when wire 1 is positive and wire 2 is negative. (Drives the actuater in)
Relay 2 energizes when wire 1 is negative and wire two is positive. Drive the actuator out
I was looking at latching relays but I need the actuator to stop when the coil is de-energized. My understanding is they do not.
Any ideas?
