Industrial Control & Backplane Performance Features
The DS200TBCBG1AAA provides signal condition processing and direct backplane bus communication velocity compatibility required by Mark V Speedtronic controllers. The terminal card processes raw field sensor feedback, isolating input channels via passive RC networks and inline diodes to protect the TCCB core processor interface. High I/O density scaling allows 22 analog channels (including RTD temperature loops) to multiplex into dedicated multi-pin ribbon cables (JHH and JII connectors), preventing cross-channel noise propagation and signal degradation across the internal control rack backplane.
Frequently Asked Questions
Q: What are the primary signal cable connections on the DS200TBCBG1AAA board?
A: The board utilizes multi-pin ribbon cable interfaces: the JHH connector routes processed 4-20 mA milliamp input signals directly to the TCCB core card, while the JII connector routes dedicated RTD temperature signals to the same core processor.
Q: How are the selectable input channels configured for different sensor loops?
A: The board contains onboard hardware jumper blocks. Eight specific input channels can be toggled between standard 4-20 mA current signals and 1 mA sensor excitation modes by altering the corresponding jumper positions prior to applying field power.
Q: Is field-reconfiguration required when replacing older revision boards?
A: The AAA revision is fully backward compatible with earlier G1 baseline revisions. However, hardware jumpers on the replacement module must be manually mapped to replicate the exact jumper configuration of the original board before powering up the system.
Field Installation Guidelines
De-energize all power sources connected to the Mark V control panel prior to servicing the DS200TBCBG1AAA module to prevent arc flash and damage to sensitive CMOS components.
Observe anti-static precautions by wearing a grounded ESD wrist strap connected to the frame earth terminal during board removal and handling.
Loosen the mounting screws along the edge of the board and verify correct wire terminal labels before disconnecting field wiring from the terminal blocks.
Set hardware jumpers on the replacement DS200TBCBG1AAA board to match the exact input modes (4-20 mA vs. 1 mA) configured on the unit being replaced.
Align the board into the mounting slots, secure it with the retainers, and connect the JHH and JII ribbon cables firmly to ensure full electrical contact. Ensure shield grounding wires are terminated at the designated earth ground terminal block with standard thread engagement.
