FIELD: automatics.
SUBSTANCE: present invention refers to automation means and can be used in process control systems in chemical industry, heat engineering as well as for generating signals of various frequency and amplitude. The effect of the invention is achieved by the fact that the control contains a detection unit of input signal deviations from the specified value of dead zone, extreme points indicator, null element, setting devices of output signal levels, a switch, and switching elements. Peculiar feature of the control consists in the possibility of changing its static and dynamic characteristics by means of changing the settings. In particular, operation algorithm of the device allows implementation therein both of positive and negative variable hysteresis the value whereof is linear dependent on input signal amplitude.
EFFECT: enlarging functional capabilities of the control.
