APPARATUS FOR INPUTTING DISCRETE SIGNALS INTO RESERVED CONTROL SYSTEM FOR STAND TESTS OF SPACE-ROCKET EQUIPMENT Russian patent published in 2013 - IPC G05B9/00 

FIELD: radio engineering, communication.

SUBSTANCE: apparatus has a unit of spark protection barriers through which discrete signals of a pressure relay and other contact-type sensors are connected to a first data input of a first multiplexer, the second data input of which is connected to outputs of an input imitation register, the code state of is set by a programmable logic controller of registration-imitation through a fourth transceiver and a control unit, which also transmits values of input discrete signals from the output of a second multiplexer to said controller and through a first, a second and a third transceiver to three control programmable logic controllers of the reserved control system.

EFFECT: simple equipment for inputting discrete signals into a reserved control system for stand tests of space-rocket equipment.
