Connector Guide
JP Connector – Carries power from TCPS board to Q11, Q21, and Q51 cores – Routes power through R1, R2, and R5 cores
JQ Connector
Links DTBA board JQR socket to I/O boards
Transports contact input signals from DTBA
JR Connector
Connects DTBB board JRR socket to I/O boards
Transmits contact input signals from DTBB
JO1 and JO2 Connectors
Send contact output signals to TCRA board
JO1 goes to position four, JO2 to position five
JX1 and JX2 Connectors
Shielded twisted pair for IONET signals
Q11 writes to JX2 on TCEA board (position five, P1 core)
Q51 writes to JX connection on CTBA (R5 core)
Hardware Jumpers
– J1 and J8 – Factory testing only – J2 and J3 – Connect IONET termination resistors – J4, J5, and J6 – Set board’s IONET ID – J7 – Controls stall timer – See Appendix A in manual for jumper settings
Software Configuration
– SDCC contains main control circuits and software – I/O configuration editor on HMI sets contact input inversions – Use software for signal inversions, not hardware – General-purpose interface circuits connect to other boards
Contact Input Circuit Flow
– Signals come from DTBA and DTBB terminal boards – Travel through JR and JQ connectors to TCDA board – Board conditions the signals – Board timestamps any state changes – Sends processed signals to IONET via JX1 or JX2
Installation Guide
– Locate board in digital I/O cores Q11, Q51, or Q21 – Connect JP connector for power from TCPS board – Plug JQ and JR for DTBA and DTBB input signals – Use JO1 and JO2 for TCRA board output signals – Connect JX1 and JX2 for IONET communication – Set hardware jumpers before powering up
Debugging & Maintenance
– Check jumper settings against Appendix A – Use operator interface to verify IONET ID – Monitor timestamp changes for signal issues – Verify contact input inversions in HMI software – No special tools needed for jumper configuration
Compatibility
– Works with DTBA and DTBB terminal boards – Connects to TCRA boards in positions four and five – Communicates with TCQC board in R1, R2 – Interfaces with CTBA terminal board in R5 – Supports both AC and DC motor drives

FAQ – Frequently Asked Questions
Q1: What does the ZZ01A in the part number mean?
A: ZZ01A indicates optional firmware package included. This board comes with pre-installed firmware.
Q2: Can I use this board without setting the jumpers?
A: No. J4, J5, and J6 must set the correct IONET ID. Wrong settings stop communication.
Q3: From experience, what jumper causes the most problems?
A: J7 stall timer. Wrong setting makes the system think drives are stalled. Check J7 if you get false stall alarms.
Q4: Why do my contact input signals show wrong states?
A: Check the I/O Configuration Editor on your HMI. Signal inversions are set in software, not hardware.
Q5: Does this board work with newer GE control systems?
A: No. This DS215TCDAG1BZZ01A works only with Mark V systems. Newer Mark VI and Mark VIe use different boards.
Q6: Where can I find the jumper settings for my setup?
A: See Appendix A in manual GEH-6195. Also check the hardware jumper screen on operator interface.
Q7: What does the 12 month warranty cover exactly?
A: Warranty covers board failure from normal use. It does not cover damage from wrong jumper settings or wrong wiring.
Q8: Which shipping method is best for urgent repairs?
A: DHL Express for international. FedEx Priority for North America. UPS Next Day Air for Europe.
Selection Guide
– Step 1: Confirm your system is GE Mark V series – Step 2: Check which core you need (Q11, Q51, or Q21) – Step 3: Verify you need digital I/O (not analog) – Step 4: Decide if you need ZZ01A firmware option – Step 5: Review jumper requirements for your application – Pro tip: Buy a spare board. Mark V parts become harder to find each year. One spare prevents long turbine downtime.
