FUNCTIONAL DESCRIPTION:
IS200DTCIH1AAA is a Compact Contact Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The DTCI board is a compact contact input 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 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:
The DTCI board slides into a plastic holder, which mounts on the DIN rail. The contact inputs are wired 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. There are two screws for the SCOM (ground) connection, which should be as short a distance as possible and six screws for the 24 V dc excitation power.
OPERATION:
The function and on-board signal conditioning are the same as those on TBCI, except they are scaled for 24 V dc. High-density Euro-Block type terminal blocks are permanently mounted to the board with two screw connections for the ground connection (SCOM). The input excitation range is 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 surge on each input near the point of signal entry. The discrete input voltage signals are cabled to the VCCC 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.

How many input channels does a Compact Contact Input Terminal Board typically have?
The number of input channels can vary, but most boards offer anywhere from 8 to 32 channels, depending on the specific model and application needs.
What type of signals can the Compact Contact Input Terminal Board accept?
The board generally accepts digital signals, such as on/off states from switches, push buttons, or relay contacts. Some boards may also accept other types of signals like 24V DC inputs.
What are the power requirements for a Compact Contact Input Terminal Board?
Power requirements vary, but most boards require a low-voltage DC supply, commonly 24V DC, to operate.
