Los relés son componentes electrónicos de control fundamentales que utilizan una corriente baja (mediante una bobina) para conmutar corrientes o tensiones altas (mediante contactos).
Funciones clave y elementos de prueba
Pruebas de bobina:
Coil Resistance Measurement: Checks for open/short circuits or abnormal resistance.Pick-up Voltage Test: Minimum voltage to reliably close contacts.Drop-out Voltage Test: Maximum voltage allowing contacts to fully open.Verificación de la tensión nominal: Confirma el funcionamiento a la tensión especificada.
Pruebas de temporización:
Operate Time: Coil energization to contact closure.Release Time: Coil de-energization to contact opening.Contact Bounce Time: Duration of unstable switching during closure/opening.Contact Synchronization (Multi-channel): Measures timing differences between contact groups.Funciones adicionales (según el modelo):
Automated test sequences with pass/fail judgmentData logging and storageFail alarms (visual/audible)PC interfaces for remote control/reportingSimulated loads (resistive/inductive)Endurance testing (thousands/millions of cycles).Probadores de relés
