FUNCTIONAL DESCRIPTION:
IS230TICIH1A is an Isolated Digital 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 isolated digital input terminal board (TICI) provides 24-point isolated voltage detection circuits to sense a range of voltages across relay contacts, fuses, and switches. In the Mark VI system, the TICI is controlled by the VCCC board. Cables with molded plugs connect the terminal board to the VME rack where the I/O boards are mounted. Simplex and TMR systems are supported.
INSTALLATION:
Wiring: The 24 isolated digital inputs are wired directly to two I/O terminal blocks mounted on the terminal board. These blocks are held down with two screws and can be unplugged from the board for maintenance. Each block has 24 terminals accepting up to #12 AWG wires. A shield terminal strip attached to the chassis ground is located immediately to the left of each terminal block.
Cabling Connections: For a simplex system connector JR1 is used; for a TMR system, all three connectors are used. Cables or I/O packs are plugged in depending on the type of Mark VI or Mark VIe system, and the level of redundancy.
OPERATION:
The TICI is similar to the TBCI, except for the following items: No contact excitation is provided on the terminal board. Each input is electrically isolated from all others and the active electronics. There are two groups of the TICI with different nominal voltage thresholds. TICIH1 input voltage ranges are:

How does an isolated digital input terminal board work?
It typically uses optocouplers or transformers to provide isolation between the input signal and the output. When a digital signal is received, the board translates this signal through the isolator to ensure the output is free from electrical interference.
What are the common applications of isolated digital contact input terminal boards?
These boards are commonly used in industrial automation, process control, data acquisition systems, and any application where digital signals need to be safely interfaced with control systems.
What types of signals can these boards handle?
They can handle various types of digital signals such as TTL (Transistor-Transistor Logic), CMOS (Complementary Metal-Oxide-Semiconductor), and other standard digital logic levels typically used in industrial sensors and switches.
