This two-output circuit was found in General Electric documentation from the 1990s. The circuit uses an NTC as a sensor and the control element is an SCR.
In this oscillator a phase shift network formed by C1, C2, C3 and R1, R3, R4 determine the fase...
For inductive loads we have the configuration shown in the figure. Note that the optical coupler...
