12V/24V DC Motor Forward and Reverse Module Controller Isolated Type Non-contact Long Life | Инструменты

Model：LSD-24P30FID2

Scope of Application：12VDCOr24VDCDC motor（Operating voltage must be12-24VWithin the scope of。Have less12VOr have higher24VNone of the motors can use this product）The frequent commutation，MotorRated working current does not exceed6A。Motor jam and short circuit should be strictly prohibited，Or the motor locked current does not exceed6A。

If the motor current is relatively large，Please choose the DC motor forward and reverse module of our large current specification。

What are the characteristics of this product？

1.Due toInternal non-contact，It is possible for motorFrequentThe commutation of the applications，Non-sparking no sound，Extremely long life。However, the traditional forward and reverse controllers on the market are switched with relays.，Use the limitation on the number，Damaged after a while。

2.Due toThe control terminal is isolated from the motor，You can use the computer、Precision Instrument gauge control，The control signal will not cause misoperation due to motor interference，The performance is much higher than that of non-isolated type。

This product is the weakness of：Due to the use of the power chip，It is well known that the overcurrent performance of power tube is poor，Therefore, motor blocking and short circuit are not allowed，Otherwise, there is a chance to damage the power tube inside the product.。Customers should install fast fuse in motor circuit to protect this product。

What is the difference between this product and similar products on the market?？

Let's make a simple comparison here.，Easy for you to choose：

1.The main circuit of similar products uses relay reversing，Relay has Contact Life，The number of times of arrival should be changed。This product there is no contact，So there is no problem of life span，When switching non-sparking、No sound。

2.Similar products usually use ship switch to switch，Only suitable for customers with manual control。This product adopts DC signalling control，You can usePLC、Computer and other methods to realize automatic control，Manual control can also be realized through external switch。

3.Similar products are controlled manually，So we don't consider the issue of isolation at all。The control signal circuit and motor circuit of this product are electrically isolated。

4.Similar products can only be used for small motors of several amps。This product specification can be used for working Current（Or stall current）No more6AThe motor，But there are products of larger specifications，Can be used for motors with actual current up to 30 to 40 amps。

5.SimilarProducts are the bare board structure，No dust not moisture，Can not be used in harsh industrial environment。This product adopts full epoxy resin potting，Competent for various complex industrial occasions。

About the wiring method of motor：

Four copper terminal are used to connect direct current input and DC motor。Attention should be paid to the Positive pole and negative pole of input direct current。The output of the module is connected to a DC motor，Does not distinguish between Positive pole and negative pole。

The input direct current must be12-24VWithin the scope of，Cannot be lower than those of12V（For example6V,9VI can't），Also can not be higher24V（For example36V，48VNot even）。

On the control mode：

A A-、B B-Signal terminals to control motor reversing。The user can takeA-WithB-Connected to，ControlA WithB The break-make，The motor commutation，The two negative electrodes are connected by common negative connection。Otherwise, it is the common Yang connection method.。Common Yin and common Yang can be selected according to the user's application。

On the control signal：

The input signal range is12-24VDC。The signal should be continuous，Cannot be high or low level orPWMWaveform。

Because the control signal has been isolated from the DC motor inside this product，Therefore, different power supplies should be used for the input control signal and motor power supply.，Otherwise, the isolation feature of this product will lose its function。

FAQs example：

Q:What is the difference between this product and the general positive and negative switching device?？

A:This product is isolated，Ordinary products are not isolated。Isolation means that the signal of the control terminal is isolated from the motor，No Electrical Association。

There is no contact inside this product，Non-sparking no noise，SuitableFrequent Positive and negative start-up operation of DC motor，For example1Switch forward and reverse twice in seconds。

The input control signal of this product has interlocking function，At the same time an input signal，The motor will stop turning。

Q:Advantages of adopting isolation type？

A:Interference signal will be generated on the power supply when DC motor rotates(RFSignal、Mutation voltage，Can be observed with oscilloscope)，If the control signal is not fully isolated，The interference signal is fed back to the control terminal，It is likely to cause malfunction of the signal source of the control terminal（Such as running and flying dead halt, etc.）。

Q:What is the voltage drop on the module？

A:The pressure drop is in0.1VThe left and right。Due to the low pressure drop，Module does not substantially fever.

Q:What is the working principle of this product？

A:This productIs one of the actuators，Make the motor switch forward and reverse according to the signal you give it。It carries out a control signal（12V-24VThe signal）The command。What you need to do is to use your signal to control it.，Add the signal when you need the motor to rotate forwardA A-On，You need to add the signal when the motor reversesB B-On。How to apply this signal is decided by the customer，You can manually switch control，May be performed by the sensor control，Can also bePLCControl，And so on。
