The device of start and stop motor.
The utility model adopts the following technical solution：A kind of device of binary channels output protection frequent start-stop motor, should
Device includes air switch, motor, digital output module, and the digital output module is exported with first, second respectively
Relay connects；Control system duplex breaker is connected with the first output relay, contactor；Alarm lamp duplex breaker and
First, the second output relay connects.
The first alarm lamp is accessed between first output relay and alarm lamp the duplex breaker.
The second alarm lamp is accessed between second output relay and alarm lamp the duplex breaker.
The utility model controls two output relays respectively by two passages of digital output module, when two it is defeated
Go out contactor coil when relay output condition meets at the same time to connect, the startup and stopping of control device are come with this.Recycle defeated
Go out the contact access alarm lamp of relay, for display relay output state directly perceived.Exported in a program with binary channels
Point is used as latching point, prevents equipment equipment malfunction caused by module channels or relay are influenced by induced electricity from making.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
With reference to attached drawing 1, the utility model discloses a kind of device of binary channels output protection frequent start-stop motor, the dress
Put including air switch 2, control system duplex breaker 3, control circuit fuse 8, contactor 9, electrothermal relay 10, motor
11, digital output module 18,18 output channel of digital output module respectively with first, second output relay 12,
13, control circuit fuse 8, contactor 9, electrothermal relay 10 connect；The control system duplex breaker 3 and first, second
Output relay 12,13, contactor 9 connects；Alarm lamp duplex breaker 4 is connected with first, second output relay 12,13.
The first alarm lamp is accessed between the contact of first output relay 12 and alarm lamp duplex breaker 4
14.The second alarm lamp 15 is accessed between the contact of second output relay 13 and alarm lamp duplex breaker 4.This reality
Alarm lamp is accessed using the contact of output relay with new, for display relay output state directly perceived.In a program
By the use of binary channels output point as latching point, prevent equipment equipment caused by module channels or relay are influenced by induced electricity from missing
Action.
The direct current 24V power supply duplexs breaker 5 is connected with direct current 24V power supplys 6, rack power supplies module 16.
The 1756-OA16 output modules power supply duplex breaker 7 is connected with digital output module 18.
The air switch 2 is connected with contactor 9, electrothermal relay 10, motor 11.
Digital output module 18 is 1756-OA16 digital output modules in the utility model.
Operating method：
First, all devices programming and distribution are installed in place according to wiring diagram, establish complete PLC system, and by PLC with
