FIELD: testing.
SUBSTANCE: invention relates to systems intended for electrical tests and control of control systems or their elements. Device comprises a power supply unit connected to a PWM controller power supply circuit, first and second outputs of which are connected to gates of N-channel MOSFET transistors, sources of which are connected to zero contact of signalling unit, and drains are connected to primary winding of voltage transformer, wherein voltage converter secondary winding is connected via full-wave bridge rectifier to control unit power supply circuit. Signalling unit is made on the basis of light-emitting diodes powered by voltage stabilizer, with possibility of node switching with outputs of two-position actuators position signalling units, and the control unit is made on the basis of transistor amplifiers with possibility of its switching with inputs of control units of two-position actuators.
EFFECT: possibility of using the device for maintenance of two-position actuators of various types, used to control shutoff and control valves, directly at control object.
