Functional OverviewThe DS200LPPAG1AAA is a 24-channel discrete (digital) input module in the GE Mark VIe control system. Its primary function is to collect discrete signals (contact open/close signals) generated by field devices such as sensors,
switches, and relays, convert them into digital signals that can be recognized and processed by the PLC or control system CPU,
and transmit the processed data to the GE Speedtronic turbine control system or other control equipment, enabling automated control and monitoring. Key Technical Specifications

Therefore, self-capacitive screens cannot achieve true multi-touch; interactive capacitance is also called crossing capacitance, which is the capacitance generated through the coupling of adjacent electrodes. When the sensed object is close to the electric field line from one electrode to another electrode, the interaction The change in capacitance will be felt. When the horizontal electrodes send out excitation signals in sequence, all the vertical electrodes will receive the signal at the same time. In this way, the capacitance value of the intersection of all horizontal and vertical electrodes can be obtained, that is, the two-dimensional plane of the entire touch screen. Capacitor size. When human fingers approach, the local capacitance will decrease. Based on the two-dimensional capacitance change data of the touch screen, the coordinates of each touch point can be calculated. Therefore, even if there are multiple touch points on the screen, each touch point can be calculated. the real coordinates. In both types of projected capacitive sensors , the sensing capacitance can be designed in such a way that the touch of a finger is detected at any given time. The touch is not limited to one finger, but can also be Multiple fingers. Since 2007, with the great success of Apple’s iPhone and iPad series products, projected capacitive screens have begun to develop rapidly, quickly replacing resistive touch screens and becoming the mainstream touch technology in the current market.
3. Infrared touch screen
The infrared touch screen uses a dense infrared matrix in the X and Y directions to detect and locate the user’s touch. The infrared touch screen installs a circuit board frame in front of the display . The circuit board arranges infrared transmitting tubes and infrared receiving tubes on the four sides of the screen, corresponding to a horizontal and vertical infrared matrix. When a user touches the screen, his or her finger will block the horizontal and vertical infrared rays passing through that location, and based on this, the location of the touch point on the screen can be determined. Infrared touch screens have the advantages of high light transmittance, no interference from current , voltage and static electricity, and high touch stability. However, infrared touch screens will be affected by changes in ambient light, remote controls , high-temperature objects, incandescent lamps and other infrared sources. affect and reduce its accuracy. The early infrared touch screen appeared in 1992, with a resolution of only 32×32. It was susceptible to malfunction due to environmental interference, and required to be used in a certain light-shielding environment.
After 20 years of development, the current advanced infrared touch screen has a service life of more than 7 years under normal working conditions. When tracking finger movements, the accuracy, smoothness and tracking speed can meet the requirements, and the user’s writing can be converted very smoothly. into an image trajectory and fully supports handwriting recognition input. Infrared touch screens are mainly used in various public places, offices and industrial control places that do not require very precise requirements without infrared and strong light interference.
