Description

The second closing contact of the third relay is connected to the zero potential potential bus. The delay BLOCK contains the first diode connected by the cathode to the input of the unit and to the first input of the first resistor, the second output of which is connected to the anode of the second diode. The anode of the first diode is connected to the anode of the third diode, in parallel with which a chain of a series-connected second resistor is connected and the capacitor of the second and third diodes are combined, and the anode of the first diode is a unit stroke. The essence of the invention consists in arranging the sequence of closure and opening of contacts in the circuit, through which signals are transmitted through the DAC and the de-energizer to the lock psh element, as well as the feedback circuit of the storage element and the differential force. On the phage. 1 is a structural device map; on fwg. 2 - phage stacking block, 3 - timing diagrams explaining the operation of the device ,, The device contains PAI 1, differential (| hrekretsialny amplifier 2, locking element 3, relay 4-6 with contacts respectively 4, 5j, 6 to 6, The control unit 7 is a decoding unit 8, a key 9, and a delay unit 10. The delay unit contains diodes ll-lS, resistors, 14D5, and a capacitor 16. The device operates as follows. Digital input signal is fed through pin 4j to the DAC 1. Conversion In the voltage signal from the output of the DAC 1 black amplifier 2 and pin 5 is sent to the storage element 3 one i-JS zapiotuvaty output channels (the contact of the 5 5 6. terminal; and 6, the possibility of building a multichannel output device is shown). The feedback circuit is closed via contact 6 controlled by the relay 6. At the same time, contacts 6 connect The zero buses of the DAC li amplifier 2 and the storage element 3. The interrogation of the output channels occurs in the time-multiplexing mode, therefore the signal transfer loop. C; the output of the amplifier 2 to one or another storage element 3 is assigned a small time interval. The transfer is made by briefly closing the contacts 5 j, 6 and 62 of one or another output channel. In order to avoid distortion of the analog value transmitted to the output, the following conditions should be broken (see Fig. 3) 1, Contacts 5, 6,, b should be closed only after reliable closure of contact 41. 2, Pins 5, 6 and 6 must be open before contact 4, 3, Contacts 5.j must be open before contacts 6 and 6-2 to avoid looking at amplifier 2. Conditions 1 and 2 are implemented using the control unit 7, and condition 3 using the delay unit 10, which ensures earlier opening of the contacts 5 in comparison with the contacts of the relay 6. The control unit 7 serves all channels of the device when the corresponding interrogation signals are applied to it. The delay unit 10 is single-channel, therefore, when building a multi-channel device, for each of the information selection channels, anaphogic block is required. The proposed device allows, without slowing down the readout of information, to avoid distortion of the transmitted signals, even if there is a natural variation in the triggering and releasing moments of the relay and thus .fbif, to increase the accuracy of the transmission. Claim 1, A device for storing and retrieving information containing a digital-to-analog converter connected to the first input of an differential amplifier, a storage element and a relay, and so on, in order to improve accuracy without slowing down the cycle readout, the device contains a control unit, the first output of which is connected to the winding of the first relay, through the closing contact of which of the device is connected to the input / .um of the digital-analog converter, the decoding unit connected to the second input control power supply voltage source connected via a key to the winding of the second relay and to the input of an additionally inserted delay unit, the key control input connected to the output of the decoding unit and the delay of the output of the delayer connected to the winding of the relay {differential amplifier output via a make contact The second relay is connected to the input of the storage element, the output of which is connected via the first closing contact of the third relay to the second input of the di (|) ferenchy force | the second closing contact of the third turnip is connected to the tire) of the goose sweat of the 1st cycle. 2, the apparatus according to claim 1, characterized in that the delay unit
