DS200DTBBG1 Turbine Control System

Functional Overview
The DS200DTBBG1 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.

Brushless DC does not have brushes; at the same time, in brushless DC motors, the stator is a permanent magnet and the rotor is a winding structure. In brushless DC motors, the stator is a winding and the rotor is a permanent magnet. If the winding is still on the rotor, you have to rely on physical contact to energize the winding, which does not solve the problem of brush aging. In the brushless DC motor, the winding exists in the stator and has three phase wires; when working, the input and output currents are successively supplied to the three phase wires to achieve the purpose of commutation. In brushless DC, the electromagnetic force generated by the rotor and stator is the same as that of brushed DC.

For brushless DC motors, it is not necessarily whether the stator is inside or outside. A motor with a rotor outside and a stator inside is generally called an external rotor motor. The hub motor is a very special external rotor motor.

Brushless DC motor, why is it classified as AC motor?

This is because when we supply power to the controller of brushless DC and permanent magnet synchronous motors, we supply DC power, so it is called brushless DC; however, after the DC power is inverted through the motor controller, it communicates with the motor. For the three connected phase lines, the power supply type changes to AC. Only the changing phase voltage of AC can cause the current on the three phase lines of the motor to continuously reverse direction, so the motor is classified as an AC motor.
