Functional Overview
The DS200SDCIG1AHB 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.

Certifications and Safety

This module is UL certified and can be used in both hazardous and non-hazardous locations. The UL certification covers various classes and divisions, and relevant UL mark documents are available for reference.


XLB=XLA+KXXB

YLB=YLA+KYYB Formula 2-1

Among them, KX and KY are the factor coefficients of the touch screen in the X direction and Y direction respectively. This is like a spring (we know that the spring is also linear), and the pulling force is proportional to the spring elongation. KX and KY may be positive or negative, depending on the direction and characteristics of the specific touch screen installation. For each LCD touch screen, we should also calculate the K-factor of each touch screen separately.

If point A is not the origin of the coordinates, it is also any point. Equation 2-1 can be expressed as

XLB=XLA+KX(XB-XA)

YLB=YLA+KY(YB-YA) Formula 2-2

From equation 2-2 we can derive the formula for calculating the K system

KX=(XLB-XLA)/(XB-XA)

KY=(YLB-YLA)/(YB-YA) Formula 2-3

In fact, no matter in any design, humanization is a very important part. The development of information technology has brought the benefits of touch screens to people. Because touch screens can make operations simple and intuitive, more and more handheld products and public service equipment use touch screens. Touch screens include resistive touch screens” title=”Resistive touch screen”>Resistive touch screens, capacitive touch screens, surface acoustic wave touch screens, infrared touch screens, etc. Resistive touch screens are currently widely used, including 4-wire, 5-wire Line, 7 lines, etc.

2 How resistive touch screens work

2.1 Resistive touch screen structure

The working part of a typical touch screen generally consists of three parts. As shown in Figure 1, the cross section of this resistive touch screen is two transparent resistive conductor layers (glass) and an isolation layer (isolation glass beads) between the two conductors. ), and resistive coatings. The resistive conductor layer must be made of resistive material, such as indium tin oxide (ITO), which is coated on the substrate. The upper substrate is made of plastic and the lower substrate is made of glass.

The isolation layer is a viscous insulating liquid material such as Mylar. The electrode is made of materials with excellent conductivity (such as silver ink), and its conductivity is about 1,000 times that of ITO.

2.2 Principle of resistive touch screen

A resistive touch screen is a sensor that converts the physical location of a touch point (X,Y) in a rectangular area into a voltage representing the X and Y coordinates. When enough pressure is applied to the touch screen surface (such as by pressing with a pen tip or finger), contact is created between the top layer and the bottom layer. All resistive touch screens use the voltage divider principle to generate voltages representing the X and Y coordinates. As shown in Figure 2, a voltage divider is implemented by connecting two resistors in series. The upper resistor (R1) is connected to the positive reference voltage (VREF) and the lower resistor (R2) is connected to ground. The voltage measurement at the junction of two resistors is proportional to the resistance of the resistor below. In order to measure a coordinate in a specific direction on a resistive touch screen, a resistive layer needs to be biased: one side of it is connected to VREF and the other side is connected to ground. Also, connect the unbiased layer to the high-impedance input of an ADC. When the pressure on the touch screen is strong enough to make contact between the two layers, the resistive surface is separated into two resistors. Their resistance is proportional to the distance from the touch point to the offset edge. The resistance between the touch point and the ground side is equivalent to the lower resistance in the voltage divider. Therefore, the voltage measured on the unbiased layer is proportional to the distance from the touch point to the ground edge.
