GE DS200TCDAH1BJE
GE DS200TCDAH1BJE is a Digital Input/Output Board designed for GE Speedtronic Mark V series turbine control systems, managing the flow of digital (discrete) signals between the main control system and field equipment over IONET communication.
- Technical Specifications
- Series: Mark V (TCDA)
Detailed content
-
- Communication: IONET (Ethernet-based) via JX1 or JX2 shielded twisted pair
- Communication Redundancy: Dual ports (JX1 and JX2)
- Contact Inputs: Up to 32 per DTBA/DTBB terminal board configuration
- Contact Outputs: Up to 16 relays per TCRA configuration
- Input Conditioning: Debounce filtering, change-of-state detection, time-tagging
- Input Inversion: Software-configurable via I/O Configuration Editor
- Power Supply: +5 V DC, ±15 V DC (from TCPS board via JP connector)
- IONET ID: 3-bit binary setting via J4, J5, J6 jumpers
- Stall Timer: Enabled via J7 jumper to protect outputs on IONET communication failure
- Hardware Jumpers: 8 total (J1–J8) for termination, IONET ID, stall timer, and factory test
- Operating Temperature: 0°C to 50°C
- Storage Temperature: -40°C to +85°C
- Humidity: 5% to 95% non-condensing
- Agency Approvals: UL, CSA, CE (as part of Mark VI system)
- Functional Characteristics
- Acquires digital contact input signals from DTBA/DTBB terminal boards via JQ and JR 50-pin connectors
- Conditions and time-tags input signals before transmitting to main processor
- Manages contact output signals to TCRA boards for relay and solenoid actuation
- Communicates processed signals over IONET to the rest of the control system
- Typically installed in digital I/O cores (Q11 and Q51) of Mark V LM turbine control systems
- Structural Features
- Two 50-pin ribbon connectors (JQ, JR) for terminal board interface
- Two 3-pin connectors (JX1, JX2) for IONET communication
- One side-visible LED (CR9) — green when powered, flashing during processing
- Block of 10 LEDs for status and diagnostic feedback
- 8 hardware jumpers (JP1–JP8) for configuration
- Conformal coating for harsh industrial environment protection
- Application Scenarios
- Mark V Speedtronic turbine control systems
- Digital contact signal management for gas and steam turbines
- Industrial automation requiring discrete I/O over IONET
- Relay and solenoid actuation control
- Installation Requirements
- Install in Q11 and Q51 digital I/O cores of Mark V LM control system
- Route 50-pin ribbon cables carefully to minimize EMI exposure
- Configure JP1–JP8 jumpers to match the replaced board’s settings
- Set IONET ID via J4, J5, J6 to avoid address conflicts
- Power supplied by TCPS board via JP connector
- Usage Notes
- Jumper settings MUST be correctly matched to the original unit when replacing
- CR9 LED must be green and flashing to confirm proper power and processing
- Use ESD protection during handling
- Stall timer (J7) protects outputs if IONET communication fails — enable per system requirements
