Physical Construction and Component Layout
This DS200FCRRG1A DS200FCRRG1AKD firing circuit board measures 9.1 inches in length. Its width reaches 6.3 inches with a thickness of 1.6 inches. The total weight comes to approximately 1.35 pounds. Manufacturers placed 278 discrete components on this six-layer PCB. These components include pulse transformers, optocouplers, phase detectors, and timing circuits. Both DS200FCRRG1A and DS200FCRRG1AKD share the same firing control design.
Firing Channels and Output Specifications
DS200FCRRG1A DS200FCRRG1AKD provides 12 optically isolated firing channels. Each channel delivers adjustable pulse widths from 10 to 180 microseconds. Output current reaches 150 milliamps per channel for reliable triggering. Optical isolation withstands 2500V RMS between logic and power sections. The board accepts standard 5V TTL logic for input signals. Consequently, this board interfaces with most digital controllers directly.
Timing Control and Synchronization
DS200FCRRG1A DS200FCRRG1AKD uses a phase-locked loop for line synchronization. This PLL locks to the AC line frequency automatically. Firing angle adjusts continuously from 0° to 180° of the AC cycle. Shoot-through prevention circuitry blocks overlapping firing pulses. Twelve LED indicators show active firing status per channel. Green LEDs illuminate when each channel receives a firing command. Therefore, operators can verify output activity at a quick glance.
Energy Storage and Application Use
DS200FCRRG1A DS200FCRRG1AKD integrates six 220µF capacitors for bulk storage. Eight additional 47µF capacitors filter high-frequency power noise. The board draws 250 milliamps at 5V and 100 milliamps at 24V. You will find this board in GE SCR drive and power control systems. It generates firing pulses for thyristor stacks in AC and DC drives. The board operates reliably from 0°C to 55°C ambient. For example, it controls large motor starters or heating elements. Therefore, this firing circuit board provides precise phase control for industrial power applications.
