I/O Density Scaling
The DS200TBQCG1ABB supports configurable output ranges of 20 mA or 200 mA maximum current, selectable via hardware jumpers. This flexibility allows adaptation to varying sensor and actuator requirements. Analog signals are conditioned and routed to TCQA boards, ensuring deterministic conversion cycles across the Mark V LM backplane bus.
Frequently Asked Questions
Q: How are the output ranges configured? A: Hardware jumpers on the TBQC terminal board allow selection between 20 mA and 200 mA maximum current outputs.
Q: What types of signals can be connected? A: The board interfaces with 4-20 mA analog inputs and LVDT/R position inputs, routed to TCQA boards.
Q: Does the TBQC operate independently from the processor? A: Yes. Dynamic discharge circuits monitor DC link voltage and execute control actions independently of the control processor.
Field Installation Guidelines
Ensure proper seating in location nine of the Mark V LM rack with full connector engagement.
Maintain shielded cable grounding at a single point to suppress EMI.
Route analog signal wiring separately from high-voltage lines to minimize interference.
Verify jumper settings for correct output range before energizing.
Observe ambient temperature limits (-30 to 55 deg C) during installation.
