Abstract
A tamper detection system for a controller includes a housing, a circuit board mounted in the housing, a voltage input line on the circuit board receiving an operating voltage, a light detection circuit mounted on the circuit board receiving the operating voltage from the voltage input line and a signal conditioning device conditioning the operating voltage and connected to the light detection circuit. The light detection circuit interrupts the operating voltage at the signal conditioning device in response to detecting a source of light having a light value greater than a threshold.
