FUNCTIONAL DESCRIPTION:
IS230TICIH4A is an Isolated Digital Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic 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. 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

What is an Isolated Digital Input Terminal Board?
An Isolated Digital Input Terminal Board (TICI) is a circuit board used in distributed control systems (DCS) to sense voltage signals from switches, relays, and fuses. The isolated design ensures that each input is electrically separate, preventing interference and protecting the system’s electronics. This makes the board essential for reliable and safe automation operations.
What voltage ranges does it support?
The IS230TICIH4A supports multiple voltage thresholds: 70–145 V DC, 200–250 V DC, 90–132 V AC (47–63 Hz), and 190–264 V AC (47–63 Hz). Each input is configured to detect specific voltage ranges for precise signal monitoring in industrial automation applications.
How does the board connect to the VME rack?
The board uses molded plug cables to connect to the VME rack, with a JR1 connector for simplex and all three connectors for TMR systems. This ensures proper communication with I/O boards and the VCCC controller.
