Why didn't you use transistors instead of relays?
We looked into it, and to tell you the truth, transistors have some issues for high current loads. First off, you have to know if the load is coming "above" or "below" the transistor to select the correct one. Further, they dissipate a decent amount of power at higher current levels, and would require a heat sink (more complexity and more cost). When you look at the high-end driver transistors with overtemp protection and the like, they end up costing more than the relays that they would replace! Because of this, we chose to use state-of-the-art compact automotive relays to allow for the highest degree of application flexibility.
Can I use this module with things other than the TrackCoach ProShift I/O?
Sure! All it takes to use this module to drive high loads is a 12 VDC source (down to about 5 volts) and some method to switch the relay on and off. For more information on how to wire the module, see the schematic in the document section.
What is the FES return and warranty policy?
