Precision Analog Interface for EX2000 Drives
The GE DS200TCCAG1BAA serves as a multifunctional analog input/output board for the EX2000 series drive systems. This board processes critical analog signals for speed, voltage, and current regulation loops. It conditions signals from transducers like LEMs (current sensors) and LVDTs (linear position sensors) for the main regulator. The DS200TCCAG1BAA also transmits processed analog data to the digital signal processor board for closed-loop control. Its application-specific design makes it ideal for demanding paper mill, metal processing, and crane drive applications.
Input Channels and Sensor Interfaces
The board features 13 single-ended analog inputs and 2 high-speed differential inputs for precise measurements. Signal conditioners handle inputs from a 0-1000 Hz magnetic pickup, an AC voltage input (0-5000 Hz), and a speed sensor. The DS200TCCAG1BAA also provides a local DC input for the master speed reference and a +/-2 mA input for load sharing applications. Furthermore, the board generates a +10 VDC and -10 VDC reference for analog circuits. It includes a 5 VDC reference specifically for LEM current sensors.

Configuration and Maintenance
The DS200TCCAG1BAA includes several jumpers for configuration: JP1 selects line or tachometer feedback, JP2 sets current feedback scaling, and JP3 configures the master speed reference . Green LEDs for +5V and +24V power provide visual indication of board health . Over time, components such as capacitors and optocouplers may degrade, affecting measurement accuracy . GE recommends periodic calibration and inspection of the analog I/O board in critical drive applications .
