Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Automatic controllers > pneumatic only > with auxiliary power > in which the output signal represents a discontinuous function of the deviation from the desired value, i.e. discontinuous controllers

CPC:

Automatic controllers (G05B13/00 takes precedence) > pneumatic only > with auxiliary power > in which the output signal represents a discontinuous function of the deviation from the desired value, i.e. discontinuous controllers

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
