The wiring method is shown in the figure below:
This wiring method is used when the working voltage of the sensor is different from the input voltage of the PLC, take the transistor part of the encoder, and connect it to the power supply in series to connect to the PLC in a non-voltage form. But it should be noted that the voltage of the external power supply must be below DC30V, and the switching capacity is below 35mA per phase. If the working voltage exceeds this working voltage, the encoder may be damaged.
Wiring description: The brown wire of the encoder is connected to the positive electrode of the encoder working voltage, the blue wire is connected to the negative electrode of the encoder working voltage, the output wire is connected to the input point of the PLC in turn, the blue wire is connected to the negative electrode of the external power supply, and the positive electrode of the external power supply is connected to the input of the

How to choose a professional and stable wireless 4G aggregate encoder
The continuous development of new media is changing the lifestyles of more and more audiences. Whether it is corporate events or outdoor programs, weddings, parties, events, etc., we want to record this beautiful moment through live broadcast. At present, there are generally two live broadcast methods, one is mobile phone live broadcast, and the other is professional live broadcast equipment. Mobile phone live broadcast is suitable for small occasions, simple live broadcast with goods, mobile phone live broadcast is simple to operate, shooting angles, and presentation pictures do not need to be diversified. Camera live broadcast mainly realizes live broadcast through cameras, usually used for talk show live broadcast, event live broadcast, conference live broadcast, school teaching live broadcast, sports event live broadcast, etc.; for professional outdoor live broadcast, how to choose pro

How to judge the encoder
Encoder
An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a signal form that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code wheel and the latter is called a code ruler. Encoders can be divided into contact type and non-contact type according to the read-out mode; according to the working principle, encoders can be divided into two types: incremental and absolute. The incremental encoder converts the displacement into a periodic electric signal, and then converts this electric signal into a counting pulse, and the number of pulses represents the magnitude of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so its indication is only related to the start and end positions of the measurement, and has nothing to d

The working principle of encoder quadrature encoding
Quadrature encoder (also known as dual-channel incremental encoder), used to convert linear shifts into pulse signals. By monitoring the number of pulses and the relative phase of the two signals, the user can track the rotation position, rotation direction and speed. In addition, the third channel is called the index signal, which can be used to reset the position counter to determine the absolute position.
working principle:
The incremental encoder converts the encoder's steering into the timing and phase relationship of the A-phase and B-phase pulses through two internal photosensitive receiving tubes. The encoder also outputs a Z-phase pulse per revolution to represent the zero reference position.
As shown in Figure 3-1, points A and B correspond to two photosensitive receiving tubes, the distance between points A and B is S2, and the grating distance of the encoder is S0 a

Daily maintenance and maintenance methods of absolute encoder
Absolute encoder is a kind of rotary encoder. Its characteristic is: absolute encoder is determined by mechanical position. It does not need to remember, do not need to find reference point, and does not need to keep counting. When do you need to know the position and when Just go to read its location. In this way, the anti-interference characteristics of the encoder and the reliability of the data are greatly improved.

How to use Thousand Vision HD Encoder to stream to 16 live broadcast platforms
Video live streaming is currently the hottest industry. Manufacturers, anchors, and consumer groups are growing rapidly, and many live streaming platforms are also emerging. So is there a live broadcast device that can push the same live broadcast to multiple live broadcast platforms, thereby exponentially covering more user groups?

Sony released the XEVC format on August 21, and Sony cameras H.265 encoder, 50/60p, 10bit followed? On August 8 Sony BIRTV pre-show conference, announced August 21 Sony’s new 4K ultra-high-definition camera The world premiere of the carrying machine, the specifications are higher than the Z580 in the picture.

Experience] What signal output does the absolute value signal encoder have (1, 2) I have introduced many times before that there are two types of cable displacement sensor output, digital signal output and analog signal output, and digital signal output is also divided into incremental pulse signal output and absolute value signal output. Today, I will introduce the system. Which signals are also divided into absolute value signals.

Maintenance of rope encoderSome points of attention for maintenance Maintenance of rope encoder|Some points of attention for maintenance What kind of maintenance is needed for the rope encoder in use? What failures will occur in the use of the rope encoder? How to repair after failure? Today in the editor of okplazas.com, I will take everyone to understand the precautions in the maintenance and repair of the rope encoder.

Encoder wiring specification and 5-wire encoder wiring method Encoder wiring specification Encoder is a device that compiles and converts physical signals into signals that can be used for communication, transmission and storage. Used in speed control or position control system detection elements. The on-site transportation vehicles all use the CEV65 M type encoder of Dier TR manufacturer, where C means compact absolute, E means optical, V means real axis, M means multi-turn, and 65 means shell 65mm.
