FUNCTIONAL DESCRIPTION:
DS200DSFBG1A is a Contactor Driver Board manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Control Systems. The existing Shunt Feedback Amplifier Circuit is alternatively labeled as series-derived shunt-fed feedback or current shunt inverse feedback. In this setup, the feedback network captures a portion of the output current, generating a feedback voltage that operates in parallel with the input signal voltage. As the feedback diverts the input, the input impedance is decreased due to the feedback. Conversely, the output impedance increases as a result of the feedback network being in series with the output.
Here feedback is from the emitter of the second stage to the base of the first stage through resistor Rf. In this input voltage (Vin2) to the second stage is much larger than the input voltage (Vin1) to the first stage, because of the amplifying action of transistor Q1, and is in phase opposition to it (i.e., phase difference of 180°). Voltage Ve2 is only slightly smaller than Vin2, because of emitter follower action. Also, voltages Ve2 and Vin2 are in phase. Thus Ve2 is larger in magnitude than Vin1 and has a phase difference of 180° with Vin1. When the input signal increases causing Is to increase, feedback current If also increases and so the input current Vin1 would be smaller than it would be without feedback as it is a difference between Is and If. Thus negative feedback is provided.

What is a Contactor Driver Board?
A Contactor Driver Board is an electronic circuit board designed to control and drive contactors. Contactors are electromechanical switches used for switching electrical power circuits.
How does a Contactor Driver Board work?
The Contractor Driver Board receives signals from a control system and uses them to energize or de-energize the contactor coil. This, in turn, opens or closes the contacts of the contactor, allowing or interrupting the flow of electrical current.
What are the key features of a Contactor Driver Board?
Features may vary, but common ones include input signal compatibility, protection mechanisms, status indicators, and often compatibility with different contactor types and sizes.
