FUNCTIONAL DESCRIPTION:

IS200DTCIH1A is a Simplex Contact Input with a Group Isolation Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Turbine Control Systems. The Simplex Contact Input with Group Isolation (DTCI) terminal board is a compact terminal board designed for DIN-rail mounting. The DTCI board has 24 contact inputs with a nominal excitation of 24 V dc and connects to the VCCC (or VCRC) processor board with a single cable. Two DTCI boards can be connected to the VCCC or VCRC for a total of 48 contact inputs. The terminal boards can be stacked vertically on a DIN rail to conserve cabinet space. Only a simplex version of this board is available.

INSTALLATION:

Mount the plastic holder on the DIN rail and slide the DTCI board into place. Connect the wires for the contact inputs directly to the terminal block. The Euro- Block type terminal block has 60 terminals and is permanently mounted on the terminal board. Typically #18 AWG wires are used. Two screws, 55 and 56, are provided for the SCOM (ground) connection, which should be as short a distance as possible. Six screws are provided for the 24 V dc excitation power.

OPERATION:

DTCI has the same functionality and onboard signal conditioning as TBCI, except they are scaled for 24 V dc. The input excitation ranges from 18 to 32 V dc, and the threshold voltage is 50% of the excitation voltage. The AC voltage rejection is 12 V rms. Contact inputs take 2.5 mA nominal current on the first 21 circuits, and 10 mA on circuits 22 through 24. Filters reduce high-frequency noise and suppress surgeon input near the point of signal entry. The discrete input voltage signals are cabled to the VC board (or VCRC), which passes them through optical isolators and transfers the signals over the VME backplane to the VCMI. The VCMI then sends them to the controller.

FREQUENTLY ASKED QUESTIONS:

What is a simplex contact input?

A simplex contact input refers to a single contact point that either completes or interrupts an electrical circuit based on a specific condition or input signal.

What is a group isolation terminal board?

A group isolation terminal board is a device used to isolate and organize electrical connections for multiple circuits or inputs. It helps in managing and troubleshooting electrical systems by providing a clear separation between different groups of connections.

How does a simplex contact input work with a group isolation terminal board?

The simplex contact input is connected to the group isolation terminal board, which serves as a central point for organizing and isolating the input connections. Each simplex contact input is typically assigned to a specific terminal or group of terminals on the board, allowing for easy identification and troubleshooting.
