FUNCTIONAL DESCRIPTION:

IS200TICIH1A is an Isolated Digital Contact Input Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed 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 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:

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:

• 70-145 V dc, nominal 125 V dc, with a detection of 39 to 61 V dc
• 200-250 V dc, nominal 250 V dc, with a detection of 39 to 61 V dc
• 90-132 V rms, nominal 115 V rms, 47-63 Hz, with a detection of 35 to 76 V ac
• 190-264 V rms, nominal 230 V rms, 47-63 Hz, with a detection of 35 to 76 V ac

TICIH2 Input Voltage Range Is:

• 16-32 V dc, nominal 24 V dc, with a detection threshold of 9.5 to 15 V dc.
• For DC applications, the time delay is 15 ± 8 ms.
• For an ac application, the time delay is 15 ± 13 ms.

FREQUENTLY ASKED QUESTIONS:

What is an Isolated Digital Contact Input Terminal Board?

An Isolated Digital Contact Input Terminal Board is a hardware component used in industrial control systems and automation applications. It is designed to receive and process digital signals (usually ON/OFF states) from external devices such as switches, sensors, or relays.

What are the advantages of using an isolated digital input board?

The main advantage is the enhanced protection it provides to the main control system. Isolation prevents electrical faults or surges in the field wiring from damaging the control hardware. It also improves system stability by eliminating ground loop issues and reducing signal noise. Additionally, isolated inputs allow for safer maintenance and operation, as there’s a lower risk of electrical hazards spreading through interconnected systems.

How many channels does a typical board support?

The number of input channels varies depending on the design. Common configurations include 8, 16, 32, or even 64 channels per board. Each channel is capable of monitoring an individual contact or signal, allowing multiple input points to be managed through a single board.
