The invention relates to automation, telemechanics, and computer technology and can be used in the construction of systems for remote and automatic control of technological units. A trigger with non-destructive SI information is known, which includes a remote switch diodes connected in parallel to its windings for a release delay and a neutral electromagnetic relay 1. However, such a trigger is characterized by limited functionality. Also known is a trigger containing a remote switch, two optocouplers, two resistors and an RC circuit, the first terminals of the input elements of optocouplers are connected to the first terminals of the resistors, the first terminals of the remote switching windings are connected to the common bus through the output elements of their optoelectronic switches. A disadvantage of the known trigger is the limited functionality, it can only be used in the counting trigger mode, which prevents the unification of the equipment. The purpose of the invention is to expand the functionality of a known device. The goal is achieved by the fact that in a relay module containing a remote switch, two optoelectronic switches, two resistors and an RC circuit in which the first terminals of the input elements of optoelectronic switches are connected to the first terminals of the resistors, the first terminals of the remote switch windings are through the output elements of their optoelectronic the keys are connected to the common bus, the second terminals of the first resistor and the first winding of the remote switch are connected to the first input bus, the second terminals of the second resistor and V The rear winding of the remote switch is connected to the second input bus, the second terminals of the input elements of the optoelectronic switches are connected respectively to the opening and closing contacts of the remote switch, the switch contact of which is connected to the common bus through the RC circuit, and the power bus is connected to the switch contact of the newly entered control contact group, the closing and opening contacts of which are connected respectively to the first and second input buses, between which the closing contact is connected ntakt switch counting mode. Figure 1 shows the basic circuit diagram of a relay module; figure 2 is a table of transitions RS-trigger; in FIG. 3, a transition table of a countable trigger. The relay module contains resistors 1 and 2, a remote switch 3, two optoelectronic switches 4 and 5 and an RC circuit 6, a disconnecting contact 7, a closing contact 8, and a switching contact 9 of the remote switch 3, as well as a control contact group from the closing contact 10 , the disconnecting contact 11 and the switching contact 12 and the closing contact 13 of the counting mode switch. The external connections of the module are supplied by power and signals through the power bus 14, the first input bus 15 and the second input bus 16 and the common bus 17. The first terminals of the input elements of the optoelectronic switches 4 and 5 are connected to the first terminals of the resistors 1 and 2. The first windings terminals remote switch 3 through the output elements of their optoelectronic switches 4 and 5 are connected to the common bus 17. The second terminals of the first resistor 1 and the first winding of the remote switch 3 are connected to the first input bus 15, the second terminals of the second resistor 2 and the second winding of the remote switch 3 are connected to the second input bus 16. The second outputs of the input elements of the optoelectronic switches 4 and 5 are connected respectively to the disconnecting 7 and closing 8 contacts of the remote switch 3, the switching contact 9 of which is connected via RC 6 bus 17. A power bus 14 is connected to the switching contact 12 of the control contact group, for ("10 and disconnecting 11 contacts, which are connected respectively to the first 15 and second 16 & 4 buses, between which n closing contact 13 of the switch rezkima countable. Depending on the input bus usage and the state of the even mode switch, the relay module can perform the following functions: neutral relay, RS trigger, even trigger. When using the relay mode in the neutral relay mode, an Inu 14 is supplied to the + power source (bus 17 is always connected to the power supply), and buses 15 and 16 e are used. Contact 13 of the counting circuit breaker is open. The module operates in the neutral relay mode as follows. When the input signal is applied (switching the switching contact / 12 of the control contact group from the opening contact 11 to the closing contact 10), the supply voltage is removed from the second winding of the remote switch 3 and applied to its first winding. At the same time, bus 14 in the circuit — contacts 12–10 of the control contact group — resistor 1 — input element of the optoelectronic switch 4, contacts 7–9 of the remote switch 3 — RC circuit – bus 17, a current pulse is formed, resulting in switch 4 open state. In this case, the remote switch 3 is activated by switching its switching contact 9 from the opening contact 7 to the popping contact 8. The power supply circuit of the input element of the opto electronic shred 4 is broken. The circuit of the input element of the optoelectronic switch 5 is prepared for excitation. This state is modulo equivalent: {the on-state of a neutral electromagnetic relay ,. When the input signal is removed (switching the switching contact 12 of the closing contact 10 to the opening contact 11), voltage is applied to the second winding of the remote switch 3 and the input element of the optical key 5. The switch 5 goes to the open state. The latter triggers the remote switch 3 through the second winding and returns its switching contact 9 to the initial state, i.e. the state of its closure with the opening contact 7. The initial state of the relay module is equivalent to the disconnected state of the neutral electromagnetic transmission. When using the relay module in the R5-trigger mode, the bus 14 is not activated, on. Tires 15 and 16 are used as: 5 and I-inputs, respectively (tire identification is conditional). Pin 13 of the counting mode switch is open. The transition table in the RS trigger is given in FIG. The first combination of input signals (R0,) does not cause a change in the state of the trigger, since in this case the trigger is devoid of power. The second combination of input signals (R 0, 5 1) is similar to the case of supplying the input signal, and a third combination (,) the case of removing the input signal when using the module in the neutral relay mode. All switching processes are similar to those described above. The fourth combination (R 1,. S 1) is forbidden due to the indeterminate state of the trigger. When operating in the counting trigger mode, bus 14 is not used, contact 13 of the counting mode switch is closed, and any input of buses 15 and 16, for example, bus 15, is used as the input (t is the counting trigger trigger input). . The transition table of the counting trigger is given in FIG. Thus, by changing the connections between the elements, as well as introducing the counting mode switch and the two input buses, the functionality of the relay module is expanded compared to the prototype from one to three functions. The proposed relay module configuration and enhanced functionality facilitate unification. The module, by selecting the tires used and setting the counting mode switch to a certain position, is configured to perform one of the three functions in the same way as described above.
