The Wheel Detector Amplifier

Datasheet | Buy Now!


The TX-60 is a self-contained wheel detector amplifier used for presence detection and axle pattern recognition with Tiefenbach wheel detectors. Digital output from the unit can be directly input into a number of AEI systems including the Thinkify TR-1000-AAR RFID reader.

The TX-60 features a very easy to use interface panel. LEDs on the display show the current state of the unit including status of the A and B wheel detection channels, indications for mis-wiring and line faults. In the event of a mis-wire, the unit shows not that a mis-wiring has occurred, but what needs to be changed to resolve the problem. The TX-60 interface panel will also display to the user that a line fault has occurred and what input channel it has occurred on.

Input voltage ranges from 10-36 volts (AC or DC) allow the user greater flexibility in installation.
