Definitions

  • the invention relates to an arrangement for exciting relays, in particular in signal fields in frames of digital signal and carrier frequency systems.
  • error signals are generated as messages from faulty devices and fault signals as messages about the unavailability of message connections. These lead to an urgent alarm (A alarm) or a non-urgent alarm (B alarm), which are displayed in signal fields. Acknowledged lamps are identified by a reminder lamp. Messages from signal fields are passed on to manifolds of rack rows.
  • Signal fields are known which operate with an operating voltage of -12V and those which operate with an operating voltage of -24V.
  • the object of the invention is to provide an arrangement for exciting relays, in particular for a signal field, which works with two different operating voltages.
  • a signal field with the arrangement according to the invention should, for example, be able to replace the two known signal fields.
  • a relay a parallel circuit comprising a first resistor and a first switch, and a second switch are arranged in a first series circuit connected to an operating voltage
  • Operating voltage connected comparator is provided, which outputs a logical zero when an upper value of the operating voltage is present and a logical one when a lower value is present
  • a monostable multivibrator is provided, at the input of which an excitation signal can be applied
  • a first OR gate is provided is, the first input of which is connected to the output of the comparator, the second input of which is connected to the output of the monostable multivibrator and the output of which is connected via a first switch control to a control input of the first switch
  • a second OR gate is provided, the first input of which is connected to the Exit g and its second input are connected to the input of the monostable multivibrator and its output is connected to a control input of the second switch via a second switch control and
  • the first switch at the upper value of the operating voltage is open due to a logic zero at the output of the comparator and is only closed when logic one occurs at the output of the monostable multivibrator, if the first switch is at a lower value of the operating voltage is closed due to the logic one at the output of the comparator and if the second switch is closed when logic one occurs at the input or output of the monostable multivibrator.
  • An arrangement for the individual excitation of several relays is characterized in that a decoupling diode is provided between the first switch and the relay, that n further relays are provided, that n further first series connections are provided without a first switch but with a decoupling diode that a connection of the relay-facing Connections of the decoupling diode are provided that n further monostable multivibrators with inputs are provided, that a first OR gate is provided with n further inputs, to each of which an output of the further n monostable multivibrators is connected, that n further second OR gates are provided are, whose inputs are connected to an input and an output of the assigned monostable multivibrator and whose outputs are each connected to the control inputs of the assigned further n second switches via one of n further second switch controls.
  • An advantageous embodiment of the invention is that the switches are implemented by transistors.
  • the comparator consists of a second series circuit connected to the operating voltage, a zener diode and a second resistor and an inverter connected to the center tap of this second series circuit, the output of which serves as a comparator output.
  • the arrangement according to the invention is advantageously used for operating DC voltages in the ranges of -12 V and -24 V or -24 V and -60 V.
  • Figure 1 shows an arrangement according to the invention. This contains a relay 1, a resistor 2, switches 3 and 5, a comparator 6, a monostable multivibrator 7, an input 8, OR gates 9 and 11, and switch controls 10 and 12.
  • the contact set of relay 1 is not for Invention not properly shown.
  • Relay 1 has a nominal voltage which corresponds to the lower value of the operating voltage U B.
  • the switch 3 is closed at the lower value of the operating voltage U B by the comparator 6 via the OR gate 9 and the switch control 10 and applies the relay 1 directly to the operating voltage U ⁇ .
  • the state at the other input of the OR gate 9 is now ineffective.
  • the switch 3 can only be closed by the output signal of the monostable multivibrator 7 for its pulse duration via the OR gate 9 and the switch control 10.
  • This pulse duration is dimensioned in such a way that relay 1 responds reliably.
  • the relay is connected to the operating voltage U e via resistor 2. This is dimensioned so that the minimum holding voltage is not undercut.
  • relay 1 takes place via switch 5.
  • switch 5 is closed via OR gate 11 and switch control 12, even if the excitation pulse at input 8 is shorter.
  • the switch 5 is closed bypassing the monostable multivibrator 7.
  • the OR gate 9 ' has a special position, since it combines three individual OR gates. In addition, decoupling diodes 4, 4 'and 4 "are introduced.
  • the switch 3 is only closed if at least one of the monostable multivibrator 7, 7 ' , 7 "is present at the output. Since only one switch 3 is present, all relays 1, 1 ', 1 "when a relay responds via switch 3 and the decoupling diodes 4, 4', 4" to the operating voltage U B. Relays that have already been addressed are thus briefly connected to the operating voltage U B again. This has no influence on the function of the relays already addressed The rest of the arrangement works as in the case of FIG.
  • FIG. 3 shows a comparator 6, which consists of a zener diode 13, a resistor 14 and a CMOS inverter 15.
  • the inverter 15 is operated at an auxiliary operating voltage U ' B of 10V.
  • the typical switching threshold is 5V. If the operating voltage U B is less than the sum of the voltage of the Zener diode 13 and the response threshold of the inverter 15, its output is at logic one. If the operating voltage U B is greater than this sum, the output of the inverter 15 assumes the logic level zero.
  • Figure 4 shows the arrangement of Figure 2 in more detail.
  • the arrangement contains a comparator 6 according to FIG. 3, in which the inverter 15 is implemented by a NOR gate 15 'with its first input.
  • the OR gate 9 ' consists of diodes 16, 17, 18 and the NOR gate 15' with regard to its second input on the connecting line 19.
  • the switch 3 and its switch control 10 consist of resistors 20 to 23 and transistors 24 and 25.
  • the switches 5, 5 ', 5 "with their switch controls 12, 12 ' , 12 " are realized by transistors 29 to 31 and resistors 32 to 34 .
  • the voltage of the Zener diode 13 is selected at 13 V in such a way that the corresponding input of the NOR gate 15 'lies in the range of the lower value below the switching threshold.
  • the output of the NOR gate 15 ' is thus in this region at minus potential, which causes the transistors 24 and 25 to be switched through via the diode 16.
  • the second input of the NOR gate 15 ' is therefore ineffective.
  • the relays 1, 1 ', 1 are thus connected to the operating voltage U B via the diodes 4, 4', 4".
  • the diodes 26 to 28 are quenching diodes.
