FIELD: peripheral devices of controlled station of information-control complexes for automatic control systems of distributed power objects of railway roads, oil- and gas pipelines, oil production plant and other important objects whose operation is related with safety of people and equipment. ^ SUBSTANCE: authenticity of control instructions in above mentioned systems is very important that is why apparatuses for reception, processing ad execution of such instructions must be developed and constructed at adequate great care. Apparatus includes additional units and links between its members including relays forming signals for controlling actuating mechanisms. Diagnostics units allow to identify distortions of received instruction and to fix rejection of execution of non-distorted instruction. New functional possibilities allow to control important objects with use of such apparatus. ^ EFFECT: enhanced reliability of receiving control instructions. ^ 3 cl, 4 dwg |
