Backplane Bus Communication & I/O Density Scaling
The DS200TCEBG1A expands system I/O density scaling by functioning as a high-density passive signal routing hub for the Mark V protective core. Built with four integrated signal transformers, three bayonet connectors, and a large complement of multi-pin ribbon headers (including 26-pin, 20-pin, and 10-pin arrays), the module manages galvanic signal isolation and high-density termination without adding firmware latency. Its multi-channel design routes flame detection, signal feedback, and protective field telemetry directly into the backplane communication network across dedicated connection paths labeled JKX/Y/Z and JWX/Y/Z.
Frequently Asked Questions
Q: Does the DS200TCEBG1A require software flashing or hardware jumper configuration prior to replacement?
A: No, the DS200TCEBG1A contains no software, firmware PROMs, or adjustable hardware jumpers. It functions strictly as a hardwired terminal and signal expansion interface.
Q: Why does the DS200TCEBG1A board feature eight chassis mounting screw holes?
A: The board is populated with four heavy signal transformers and multiple heavy connector bodies. The eight mounting points distribute physical load evenly across the cabinet chassis to prevent board flex under vibration.
Q: What functions do the onboard signal transformers perform on the TCEB board?
A: The four onboard signal transformers provide magnetic isolation and signal scaling for protective telemetry inputs entering the Mark V protective core assembly.
Field Installation Guidelines
- Fully de-energize the Mark V cabinet and verify that all remote field instrument power sources are isolated before servicing the card.
- Tag and record every ribbon and coaxial cable connection according to its factory-printed nomenclature (such as JKX/Y/Z, JWX/Y/Z) prior to disconnection.
- Wear a grounded ESD wrist strap bonded to the enclosure chassis during installation to prevent static damage to adjacent active modules.
- Support the heavy board with one hand while loosening or tightening the eight retaining screws; retrieve any dropped metal hardware immediately from the cabinet interior before restoring power to prevent short circuits.
What's clients say about us
Excellent Emergency Support!
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.
