Technical field

The utility model relates to a kind of PCB control panel, relates in particular to a kind of host PC B control panel with standby host control function.

Background technology

The PCB control panel is important electronic unit, is the supporter of electronic devices and components, is the supplier that electronic devices and components electrical equipment connects.

Design according to the PCB circuit board is different, and the PCB control panel is by the material of PCB, the number of plies of PCB, the size of PCB, each quantity of producing, the technique of production, minimum live width line-spacing, the aperture of minimum and the quantity in hole, and the requirements such as special process decide.

The utility model content

The technical problems to be solved in the utility model has been to provide a kind of host PC B control panel with standby host control function.

For solving the problems of the technologies described above, the utility model is realized by following scheme: with the host PC B control panel of standby host control function, it is characterized in that: described host PC B control panel comprises the PCB body and is installed in components and parts on the PCB body circuit, on the described PCB body circuit several terminals are set, No. 103 terminals and No. 104 terminals, No. 105 terminals and No. 106 terminals are electrically connected with the civil power working power, No. 324 terminals and No. 325 terminals are electrically connected with the field control self-holding contact, No. 325 terminals and No. 326 terminals are electrically connected with the field control self-holding contact, No. 327 terminals and No. 328 terminals are electrically connected with DCS control self-holding contact, and No. 328 terminals and No. 329 terminals are electrically connected with DCS control self-holding contact.

Described civil power working power can substitute with UPS uninterrupted power source or dc supply.

Described host PC B control panel is connected with circuit breaker electric.

The utility model has the advantages that: adopt the unit PCB control panel with standby host control function, easy to use, strengthened the efficient of producing, automatically control the security that the self-holding contact function has improved machine.

Description of drawings

Below in conjunction with accompanying drawing the utility model is elaborated.

Embodiment

Host PC B control panel with standby host control function, it is characterized in that: described host PC B control panel a comprises the PCB body and is installed in components and parts on the PCB body circuit, on the described PCB body circuit several terminals are set, No. 103 terminals and No. 104 terminal f, No. 105 terminals and No. 106 terminal g are electrically connected with civil power working power b, No. 324 terminals and No. 325 terminal h are electrically connected with the field control self-holding contact, No. 325 terminals and No. 326 terminal i are electrically connected with the field control self-holding contact, No. 327 terminals and No. 328 terminal j are electrically connected with DCS control self-holding contact, No. 328 terminals and No. 329 terminal k are electrically connected with DCS control self-holding contact, described civil power working power b can substitute with UPS uninterrupted power source d or dc supply c, and described host PC B control panel a is electrically connected with isolating switch e.

The host PC B control panel a of the utility model band standby host control function can adopt civil power working power b or UPS uninterrupted power source d (rated operational voltage Un≤AC230V/50hz), also can adopt dc supply c (Un≤220V), require to select arbitrarily working power by the user according to on-the-spot electricity consumption.

Having city electricity condition input function for monitoring and time-delay disconnects UPS uninterrupted power source d and maybe can keep UPS uninterrupted power source d with the external switch signal, when system adopts UPS uninterrupted power source d, can monitor the state of mains supply by No. 103 terminals and No. 104 terminal f, in case the time relay KT during the civil power abnormal on the control panel gets electronic work (delay time can be selected arbitrarily and adjust according to demand), the primary power power supply still can disconnect the working power of all control loops unusually after arriving predefined time value. also can select whether to keep UPS uninterrupted power source d by No. 105 terminals and No. 106 terminal g access external switch signals.

The utility model can provide the output of 5 tunnel working powers.

The utility model system start-stop control loop can be accepted starting and the stop signal of multichannel outside, and outside interlocking signal (signals such as pressure interlocking or excess Temperature), operation control selector switch (scene is set in starting control, stop, DCS), and have from interlock circuit, selective system Operation Mode Selection (selecting host work or standby host work) and switch mode (manual switchover or automatic switchover) are provided, when selecting host work, when system breaks down and switch mode be in automatic switchover mode, system can realize automaticallying switch by cooperating with outside PLC switch board, simultaneously all run signal (as: converting operation. the frequency conversion fault, and status indicator lamp etc.) and real-time running state (as: the given frequency of system. actual output frequency and output current, and output voltage, output torque etc., this signal is set by frequency converter correlation function parameter); When selecting host work, when system breaks down and switch mode be in the manual switchover pattern, will quit work immediately state and fault-signal exported by terminal of system.Can accept the duty input (isolating switch e closes a floodgate and the tripping alarm contact) of the isolating switch of outside strong air-cooler; and participate in control to operation and the shutdown of the strong air-cooler of main motor radiating; when isolating switch e trips; output fault-signal (dry contact signal) feeds back to host computer, and the working power of output state pilot lamp is as the state indication simultaneously.

The above only is preferred implementation of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
