The DS200TBCAG1A module routes signal lines from up to 30 individual 3-wire RTD sensors directly into the Mark V control architecture. Interface wiring is mapped through two 50-pin ribbon cable connections: connector JCC transmits RTD signals 1-15 to the TCCA board located in the R5 core, while connector JDD transmits RTD signals 16-30 to the corresponding TCCA board. The passive board traces maintain deterministic signal path integrity across the backplane bus, ensuring precise analog input data transmission to the primary data processor without adding transmission latency.
Q: Which processor core and interface board does the DS200TBCAG1A communicate with?
A: The DS200TBCAG1A provides analog signal termination for the common data processor, routing signals directly to the TCCA board within the R5 core via JCC and JDD connectors.
Q: How are RTD input channels physically distributed across the board connectors?
A: The module accepts 30 inputs for 3-wire RTDs; signals 1 through 15 route through the JCC 50-pin connector, while signals 16 through 30 route through the JDD 50-pin connector.
Q: What precautions are necessary when disconnecting the 50-pin ribbon cables from the board?
A: Technicians must pull directly on the connector housing rather than the ribbon wire itself while supporting the PCB chassis with the opposite hand to avoid flexing the board or damaging internal traces.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
