Need help with this Ultrasonic Sensor Module

http://www.bakatronics.com/shop/item.aspx?itemid=453
This page is the only thing I can find when searching for information on it.

I just started using an Arduino, I found this sensor in my college lab and want to test it. Not sure how it works and what connects to where, my knowledge about electronics is limited and I would like some help with how to connect this thing to the Arduino and an example of code that could interface with this sensor.

Your unit appears from the description to be hardware which detects an object within a 5 meter range... Essentially like an intrusion detector. Most Arduino modules are Ultrasonic

but the thing is I don't think it works exactly the same way as the one you linked, the ultrasonic sensor I have has a relay on it, which confuses me as how it works.

Your sensor has two trim pots. I assume one sets the distance at which the relay activates. Wire up two of the three relay terminals (Common and your choice of Normally Open or Normally Closed) like a pushbutton and the Arduino can tell if the relay has been triggered or not.

A Google search for Maxx Tronic MX027 turns up over 200 pages. Perhaps one of them mentions which trim pot does what.
