Input Signal Processor for Tamper Response Circuits

Product Specifications

Technical details and manufacturing context for Input Signal Processor

Definition

An input signal processor is a specialized electronic component within a Tamper Response Circuit that receives raw sensor signals, filters noise, amplifies weak signals, converts analog inputs to digital formats when necessary, and prepares clean, standardized signals for the circuit's decision-making logic. It serves as the critical interface between detection sensors and the circuit's processing core. The component is designed for industrial applications, operating over a wide input voltage range of 9–36 V DC, with a current consumption of ≤20 mA at nominal voltage. It handles signal frequencies from 0 to 100 kHz, covering typical sensor outputs, and offers a high input impedance of ≥1 MΩ to minimize loading on the sensors. The output voltage swing is 0–5 V, compatible with logic inputs, and the rise time is ≤1 μs for fast response. The operating temperature range is -40 to 85 °C (IEC 60068-2-1), with storage from -55 to 125 °C (IEC 60068-2-2). Humidity tolerance is 5–95% RH non-condensing (IEC 60068-2-78), and ingress protection is rated IP54–IP65 (IEC 60529). The supply voltage rejection ratio is ≥60 dB at 100 Hz, and output noise is ≤5 mV RMS over the full bandwidth. The compact module measures 25×20×10 mm and weighs ≤15 g, suitable for PCB mounting. Materials include silicon semiconductor, copper traces, PCB substrate, and solder. These specifications serve as reference ranges; actual values must be confirmed with the legal manufacturer or supplier for specific models and applications.

Working Principle

The input signal processor operates by receiving electrical signals from tamper detection sensors (such as vibration, pressure, or contact sensors). It first filters out environmental noise and interference using passive or active filtering circuits. Signal amplification stages then boost weak signals to usable levels. For analog sensors, analog-to-digital converters (ADCs) digitize the signals. The processed signals are then formatted and transmitted to the main circuit controller for tamper assessment and response triggering.
