I/O modules

The GE IS200ICBDH1A IS200ICBDH1ABB serves as a universal control platform for Mark VI applications. This board handles multiple control loops in a single compact module. Therefore, it reduces spare part inventory requirements for turbine operators.

Product Overview

We designed this innovation board for flexibility across different turbine types. Its reconfigurable I/O adapts to steam, gas, or hydro applications. Moreover, this unit includes onboard data logging for predictive maintenance.

Technical Specifications

Flexible Architecture

The GE IS200ICBDH1A IS200ICBDH1ABB uses an FPGA for I/O configuration. Its four aluminum capacitors filter power for the processor and FPGA. Additionally, field-programmable gates adapt to any signal type. You reconfigure the board through software without hardware changes.

Energy Storage Configuration

Four aluminum capacitors provide 18 ms of hold-up for the processor during dips. Twenty-four ceramic capacitors decouple noise from every IC power pin. A dedicated supercapacitor maintains the real-time clock for 7 days. This supercapacitor stores 0.5 F at 5V for timekeeping. Therefore, event logs retain accurate time stamps after power loss.

I/O Reconfiguration

Each of the 32 I/O points can become analog or digital individually. Analog channels support 0-10V, 0-20mA, or thermocouple inputs. Digital channels support 24V DC input or 0.5A sinking output. The board auto-detects external wiring and configures accordingly. You can change assignments dynamically while the turbine runs.

Installation Steps

Insert this control board into a Mark VI slot with dual backplane connectors. Align the GE IS200ICBDH1A IS200ICBDH1ABB with both card guide rails. Push the board evenly until both ejectors lock into position. Then tighten all four corner screws for vibration resistance. Connect external networks to the front Ethernet and USB ports.

Control Loop Features

Sixteen independent PID loops run at programmable rates from 10 ms to 1 second. Each loop includes setpoint ramping, output limiting, and feed-forward. Anti-windup logic prevents integral accumulation during output saturation. The board executes all loops sequentially without CPU overload. Loop parameters remain stored in FRAM for instant recovery after power-up.

Sequence Engine

The onboard sequence logic executes up to 512 steps in order. Each step can monitor conditions and perform actions simultaneously. Step resolution reaches 1 ms for time-critical applications. An example sequence starts auxiliary pumps before the turbine. Another sequence performs automatic synchronization to the grid. You program sequences using ladder logic or function block diagrams.

Data Logging Capabilities

The board logs up to 1000 event records in non-volatile memory. Each event includes a 32-bit time stamp with 1 ms resolution. Trigger conditions include alarm trips, setpoint changes, or operator actions. You can export logged data through the USB port to a flash drive. The GE IS200ICBDH1A IS200ICBDH1ABB also streams real-time data via Ethernet.

Application Scope

This innovation board suits turbine retrofits and new installations alike. Many power plants use the GE IS200ICBDH1A IS200ICBDH1ABB for standardizing control platforms. Its flexibility reduces the number of unique spare boards required.
