Internal Design and Signal Processing
This I/O board uses a 16-bit CPU for signal conditioning and communication. An ADC converts analog inputs to digital values for the main processor. The GE DS200SIOBG1A DS200SIOBG1AAA provides 16 digital inputs and 8 digital outputs for field devices. Four analog input channels accept 4-20 mA or 0-10 V signals. Two analog output channels drive actuators with 4-20 mA current loops. Consequently, this board serves as a complete I/O interface for turbine control applications.
Installation and Wiring Guide
First, mount this I/O control board onto standoffs inside your control cabinet. Next, connect a 24 V DC power supply to the designated terminals. Then, wire your digital sensors to the input terminals (channels 1-16). Connect your digital loads to the output terminals (channels 1-8). Wire analog sensors to the 4-20 mA input terminals with shielded cables. Use twisted-pair cables for analog outputs to reduce noise interference. The board provides LED indicators for power, run status, and fault conditions. This I/O board works with all Mark V turbine control systems and compatible field devices.
