(Throttle Position Switch / Adjustable-TPS)

 Can be use with any 0-5V sensor signal.

    The TPSr/ATPSr module is a non-contact electronic switch, no mechanical parts to ware out and no brackets to install or adjust. This module is intended to operate a relay or any electronic device by switching one side of the relay or device to ground. The relay or electronic device is switched on when the vehicle's own throttle position sensor is outputting a voltage equal to or greater then the voltage set point you have selected, in other words our module turns on at (and above) the throttle setting that you have selected.

In the standard TPSr (Non-Adjustable version), the turn-on voltage threshold can be chosen by you at the time of purchase.  If you don't tell us what you want you will get the standard 4.5V setting.

In the standard ATPSr (adjustable version): The module comes with three slide switches on the front of it that allow you to adjust the turn-on voltage threshold, in eight steps, from as low as 0.1V to as much as 4.9V with a 0.1V turn off hysteresis threshold to reduce relay cycling. If you don't tell us what you want at the time of purchase, you will get the standard settings of 4.0V to 4.9V.  If you don't want the standard voltage range settings, email us your desired voltage range at the time of purchase.

The TPSr/ATPSr modules are Factory Re-Programmable; If you ever need new settings programmed into your module, just email us for a reprogramming quote and Return instructions.
