Description
Technical Summary & Role
The DS200SLCCG3AGH (SLCC) is the primary LAN Communication Board for the GE Speedtronic Mark V turbine control system. Operating as a core node controller, it handles internal rack communication, data distribution across triple-modular redundant (TMR) cores (\langle A \rangle, \langle B \rangle, \langle C \rangle), and external interfacing with operator workstations (HMIs) via Arcnet or Ethernet communication links.
Companion Mark V Hardware Reference
If you are maintaining or rebuilding a Mark V control core that utilizes the SLCC communication card, it is frequently deployed alongside these related core and termination modules:
| Part Number | Description / Function |
| DS200TCCBG1BED | Common Extended Analog I/O Board (TCCB) |
| DS200TCEBG1BAA | Protective Termination Expander Board (TCEB) |
| DS200TBCBG1AAA | RTD Input Termination Board (TBCB) |
| DS200DTBAG1AAA | Drive Termination Board (DTBA) |
Quick Logistics & Procurement Note
- Availability: Stock levels for legacy Mark V communication boards like the DS200SLCCG3AGH fluctuate based on certified surplus and repair-pool turnaround times.
- Firmware / Revision Check: Ensure that any replacement SLCC board matches your system software version and jumper configurations precisely to avoid communication mismatches on the turbine network.
