TDEPS electronic pressure switches with relay output use redundant half-bridge circuitry for high-shock/high-vibration environments. Features include ±0.25% BFSL total error band (includes nonlinearity, hysteresis, and nonrepeatability); 9 to 28-Vdc power supply; 250-Vac/Vdc relay output (5-A maximum); compensated and operating temperature range of –40 to 194°F; and redundant sensing elements.If one element fails, the switch continues to operate on the remaining elements.
