intelligent vibration switch, programmable (via USB)
PCB 686C01 Vibration Switch - The PCB 686C series of electronic vibration switches offer the widest range of parameterization, yet configuration is simple thanks to USB connectivity and an intuitive configuration program. In the PCB 686C series of vibration switches, parameters such as warning and alarm levels, activation and alarm delay, alarm hysteresis, startup threshold level or blocking, and environmental vibration level can be adjusted. The solid-state relay output device can be easily interfaced by defining the relay mode, which can be normally open or closed, latched or unlatched. Moreover, the threshold of the PCB 686C series vibration switches can be easily set beyond computer-free operation with a single magnet by initiating the MAVTTM function.
