DS200RTBAG3AGC Turbine Control System

Functional Overview
The DS200RTBAG3AGC 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.

1.1 Four-wire resistive screen

The two transparent metal layers of the four-wire resistance analog technology work with a constant voltage of 5V added to each layer: one vertically and one horizontally. A total of four cables are required. Features: High resolution, high-speed transmission response. Surface hardness treatment to reduce abrasions, scratches and chemical protection. Available in glossy and matte finishes. Once calibrated, it has high stability and will never drift.

1.2 Five-wire resistive screen

The base layer of the five-wire resistance technology touch screen adds voltage fields in both directions to the conductive working surface of the glass through a precision resistor network. We can simply understand that the voltage fields in both directions are applied to the same working surface in a time-sharing manner. The outer nickel-gold conductive layer is only used as a pure conductor. There is a method of detecting the X-axis and Y-axis voltage values ​​​​of the inner ITO contact point time-sharing after touching to measure the position of the touch point. The five-wire resistive touch screen requires four leads in the inner layer of ITO, and only one conductor in the outer layer. The touch screen has a total of 5 leads. Features: High resolution, high-speed transmission response. High surface hardness reduces abrasions, scratches and resists chemical treatments. It can still be used after 30 million contacts with the same point. Conductive glass is the base material. Once calibrated, it has high stability and will never drift. The five-wire resistive touch screen has the disadvantages of high price and high environmental requirements.

1. 3 Limitations of resistive screens

Whether it is a four-wire resistive touch screen or a five-wire resistive touch screen, they are a working environment that is completely isolated from the outside world. They are not afraid of dust and water vapor. They can be touched by any object and can be used to write and draw. They are more suitable for the field of industrial control. and limited-person use within the office. A common disadvantage of resistive touch screens is that because the outer layer of the composite film is made of plastic material, uninformed people may scratch the entire touch screen if they touch it too hard or use a sharp object, causing it to be scrapped. However, within limits, scratches will only damage the outer conductive layer. Scratches on the outer conductive layer do not matter for five-wire resistive touch screens, but are fatal for four-wire resistive touch screens.
