Technical Specifications

Physical Construction and Component Layout

This DS200DSFBG1A DS200DSFBG1ACB printed control card measures 7.5 inches in length. Its width reaches 5.1 inches with a thickness of 1.3 inches. The total weight comes to approximately 1.08 pounds. Manufacturers placed 198 discrete components on this six-layer PCB. These components include analog converters, isolation amplifiers, control logic, and power regulation circuits. Both DS200DSFBG1A and DS200DSFBG1ACB share the same control card design.

Input Channels and Signal Conditioning

DS200DSFBG1A DS200DSFBG1ACB provides eight independent differential analog input channels. Each channel accepts ±10V voltage signals from field devices. Alternatively, each channel accepts 4-20 mA current loop signals. A 14-bit analog-to-digital converter ensures high measurement precision. Input accuracy stays within ±0.3% of the full scale range. The board conditions each signal before passing it to the controller. Consequently, this card captures critical process data with excellent fidelity.

Output Channels and Control Interface

DS200DSFBG1A DS200DSFBG1ACB delivers isolated analog outputs for actuator control. Each output provides either voltage or current signals as needed. A 12-bit digital-to-analog converter generates smooth control signals. Response time measures 5 milliseconds typical for dynamic applications. Isolation separates each output channel from the backplane. This isolation withstands 1500V AC for safe field wiring.

Energy Storage and Application Use

DS200DSFBG1A DS200DSFBG1ACB integrates four 470µF capacitors for bulk energy storage. Six additional 100µF capacitors filter high-frequency power noise. The board draws 200 milliamps at 5V and 50 milliamps at ±15V. You will find this control card in GE Mark V and Mark VI turbine systems. It provides analog interface between field sensors and the main controller. The board operates reliably from 0°C to 55°C ambient temperature. For example, it monitors temperature, pressure, and position signals. Therefore, this printed control card delivers precision analog control for industrial automation applications.
