ABSTRACT:
This invention relates to automatically or manually activated solid state control devices and, more in particular, to a diode, transistor, thyristor and logic function control apparatus. The device performs input signal translations, control functions, multiple step counting and features additional series, as well as in parallel connected input sensing and processing circuits. All accepted input data is available at corresponding power output terminals which are, furthermore, joined to direct or delayed acting control circuits of a multi-function controlled power output stage. The output functions comprise a constant control power output, a timed and alternating on-off controlled power output, an automatic or manually controllable device reset and a number of tone generators, including an AC power output stage. The device is designed to serve in industry and homes for control and security purposes, where its versatility, small size and extremely low power consumption on standby makes it especially attractive.
