FIELD: electricity.
SUBSTANCE: device to enter digital signals into a redundant control system for bench testing of rocket and space equipment comprises a unit of spark protection barriers, through which digital signals of pressure relays and other sensors of contact type connect to the first information input of the first multiplexer, to the second information input of which outputs of an input imitation register are connected, and its code status is set via a control unit with a duplicating programmable logical controller of the control system.
EFFECT: improved quality of preparation and reliability of redundant systems to control tests of rocket and space equipment items identified in an existing system of bench systems operation quality support by a number of failures within a control system life.
