Description
Technical field
The utility model belongs to the electronic circuit technology field, especially relates to a kind of pick-up unit for PLC digital module short trouble.
Background technology
PLC is programmable logic controller (PLC), it adopts a class programmable memory, be used for its internally stored program, actuating logic computing, sequential control, regularly, the user oriented instructions such as counting and arithmetical operation, and by numeral or analog pattern input/output various types of machineries of control or production run.PLC essence is a kind of computing machine that is exclusively used in Industry Control, it is widely used aborning, but due to a variety of causes, the situation that PLC functional module, chip burn out can occur, wherein digital module is easier to burn out, and the situation that the polylith digital module burns out simultaneously can appear, sometimes the circuit of module is through maintenance, and when just resuming production, other digital module is burnt again, do not have rule to follow, have a strong impact on production.When producing short trouble, lack detection means effectively in prior art, usually can not judge very soon the guilty culprit position, cause that in PLC, in a single day digital module burns out, just slowly can't repair, had a strong impact on production efficiency.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of PLC digital module short trouble pick-up unit, use it can process fast PLC digital module short trouble, resume production rapidly.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of PLC digital module short trouble pick-up unit, comprise power supply, air switch, fuse, relay and connection terminal, described power supply is connected with air switch, air switch is connected with fuse, fuse is also connecting relay, connection terminal is two, and one of them is connected with relay, and another is connected with power supply.
As a kind of technical scheme of the present utility model, also comprise the guide rail of strip, described power supply, air switch, fuse, relay and connection terminal all are arranged on guide rail.
As a kind of technical scheme of the present utility model, also be in series with transformer between described power supply and relay.
Compared with prior art, by the technical scheme that adopts the utility model to provide, can detect rapidly the damaged condition of module, improve maintenance and production efficiency, save cost.The guide rail setting makes the wiring of this device neatly clear.The utility model is simple in structure, and is with low cost, simple to operate, is easy to be extended and applied.
Description of drawings
Fig. 1 is embodiment one PLC digital module short trouble structure of the detecting device schematic diagram.
Fig. 2 is the PLC digital module short trouble structure of the detecting device schematic diagram that is connected with transformer.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand following embodiment and only be used for explanation the utility model and be not used in restriction scope of the present utility model.Need to prove, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of particular elements geometric center.
Embodiment one:
PLC digital module short trouble pick-up unit as shown in Figure 1, comprise power supply, air switch, fuse, relay and connection terminal, described power supply is connected with air switch, air switch is connected with fuse, fuse is also connecting relay, connection terminal is two, and one of them is connected with relay, and another is connected with power supply.
Digital module in PLC is generally two kinds, and a kind of is the 24V digital module, and another kind is the 220V digital module.When detecting the failure condition of 24V digital module, in PLC digital module short trouble pick-up unit, power supply should be 24V, can be by conventional 220V out-put supply is obtained by the transformer transformation, as shown in Figure 2.Two terminals of this device are connected respectively to the two ends of 24V digital module, and close air switch, when if circuit is connected, the corresponding actuating of relay, and fuse is normal, illustrates that the 24V digital module is normal, is provided with light emitting diode on relay, this light emitting diode lights when the actuating of relay, and representation module is normal; When if circuit is connected, relay is failure to actuate or fuse damages and illustrates that this 24V digital module is in short circuit or the malfunction such as open circuit.
When detecting the failure condition of 220V digital module, in PLC digital module short trouble pick-up unit, power supply should be 220V, can directly use conventional 220V out-put supply.Two terminals of this device are connected respectively to the two ends of 220V digital module, and close air switch.Identical with the situation of test 24V digital module, if when circuit is connected, the corresponding actuating of relay, and fuse is normal, illustrates that the 220V digital module is normal; When if circuit is connected, relay is failure to actuate or fuse damages and illustrates that this 220V digital module is in short circuit or the malfunction such as open circuit.
As a kind of technical scheme of the present utility model, also comprise the guide rail of strip, described power supply, air switch, fuse, relay and connection terminal all are arranged on guide rail.The guide rail setting makes this device wiring neatly clear, easy operating and taking in.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-described embodiment, also comprises the technical scheme that is comprised of above technical characterictic combination in any.
