Frequently Asked Questions

What is IS200TBQAH1A?
It functions as DSP (Digital Signal Processor) Control board developed by GE

What is the purpose of the terminal board in the Mark VIe I/O modules?
The terminal board is a critical element that is mounted to the cabinet. It comes in two primary variations: S and T types. The terminal board serves as a foundational connection point for various I/O points and facilitates the communication between external signals and the control system.

What distinguishes the S-type terminal board from the T-type terminal board?
The S-type terminal board provides a unique feature - a single set of screws for each I/O point. This design allows for a single I/O pack to condition and digitize the incoming signal. On the other hand, the T-type terminal board is distinct in that it fans out inputs to three separate I/O packs for processing and conditioning.

In what scenarios is the S-type terminal board commonly used?
The S-type terminal board is employed in scenarios where a single set of screws for each I/O point is sufficient. It is suitable for simplex, dual, and dedicated triple modular redundant (TMR) inputs. By utilizing one, two, or three boards, this type of board supports these different operational configurations.
