Backplane Bus Communication Velocity & I/O Density Scaling

The DS200TBQAG1A scales thermocouple I/O density by multiplexing 180 direct field wire connections through terminal blocks TB1 and TB2 into three 20-pin ribbon headers (JAR, JAS, and JAT). Channelized signal paths (covering signal numbers 1 through 45) pass directly to the connected TCQA board, preserving rapid signal propagation without intermediate processing delays. This fixed hardware pathway maintains full firmware flash compatibility and sustained backplane bus communication velocity across triple-redundant Mark V turbine controller racks.

Frequently Asked Questions

Q: Are there hardware jumpers on the DS200TBQAG1A board to configure thermocouple input types?

A: No, the DS200TBQAG1A features a jumper-less design; all signal routing and configuration are handled via the connected TCQA board and system software.

Q: How are the 20-pin ribbon cable connectors assigned on the DS200TBQAG1A board?

A: Connectors JAR, JAS, and JAT interface directly with the TCQA board, each routing distinct subsets of thermocouple signal channels 1 through 45.

Field Installation Guidelines

De-energize all power sources to the Mark V rack and isolate field thermocouple circuits before opening the enclosure.
Label each connected field wire with its designated terminal number on TB1 or TB2 prior to removal.
Loosen screw terminals only enough to release field leads without fully backing out the terminal screws.
Grasp ribbon cable connectors exclusively by their plastic headers when unplugging from JAR, JAS, and JAT; pulling directly on ribbon cables can sever individual conductors.
Support the board securely with one hand while loosening the five rack-mounting screws, as the assembly carries added weight from the dual 90-pin terminal blocks.
