The invention relates to automation and computer technology and can be used in control systems, and control, data processing and automatic control. A reversible counter on a relay is known, which contains on-off electromagnetic counting relays, semiconductor valves, a control relay and a reverse relay l. The disadvantage of such a device is its complexity, due to the use in each discharge of the counter two relays and four semiconductor valves. A reversible counter on a relay is known that contains self-holding two-winding electromagnetic relays, semiconductor diodes, a control relay, and a reverse relay 2.

The switching contact 51 of the reverse relay group 29 is connected to the common bus 52. An input pulse is fed to the input bus 53 of the device 6. The counter operates as follows. In the initial state, all windings of the relay are de-energized. The first counting pulse 4 through device 6 via bus 1 via contacts 2 and 50 of the reverse relay goes to the kQ bus for controlling odd relays, to the winding of relay 1 connected through diode 17, contacts 28 and 51 of the reverse relay to the common bus 52. Relay 1 operates and through pin 3, it connects the winding 8 of relay 2 to the bus 37. After the input pulse has stopped, device 6 triggers the bus 52 to the bus kk. When the second pulse arrives at the device 6, the pulse from the bus kk through the contacts 5 and kj of the reverse relay. enters the bus 37 and from it to the winding 8 of relay 2 connected via diode 18 and contacts 28 and 51 of the relay to bus 52. Relay 2 operates and prepares the operation circuit of relay 3 through contact 33, and device 6 switches bus 53 to the bus 41, i.e. switches pulses to odd-numbered relay bus 40. When subsequent pulses arrive at the device input bus 53, relays 4 and 5 are triggered. Thus, the input-pulses are summed up. If, after triggering, for example, relay 2, to switch the contacts of group 29.43 and 46 of the reverse relay, then when the next odd pulse arrives, relay 2 is triggered on the winding 13, while the odd input pulse from the bus 41 odd pulses of the device b is through closed contacts 42 and 48 the reverse relay goes to bus 37, to q MOTKy 13. relay 2, which is triggered through diode 23, contacts 31 and 51 of the rereverse and bus 52.
