FUNCTIONAL DESCRIPTION:

IS230TICIH3A is an Isolated Digital Input Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed 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 VIe system, the PDIA I/O packs plug into the TICI. One, two, or three PDIA packs plugins to support a variety of system configurations.

INSTALLATION:

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. 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 VIe system, and the level of redundancy. For a Mark VIe system, the I/O packs are plugged into TICI and attached to side-mounting brackets. One or two Ethernet cables are plugged into the pack, and firmware may need to be downloaded.

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. TICIH3 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

FREQUENTLY ASKED QUESTIONS:

What is an Isolated Digital Input Terminal Board?

An Isolated Digital Input Terminal Board is an electronic device used to interface digital input signals to a computer or microcontroller. The board provides electrical isolation between the input signals and the computer to protect against voltage spikes and ground loops.

Why is isolation important in a Digital Input Terminal Board?

Isolation is crucial to protect sensitive electronic components from high-voltage transients and electrical noise. It ensures that the computer or microcontroller does not receive harmful voltages that could cause damage or affect performance.

What types of signals can an Isolated Digital Input Terminal Board handle?

These boards are typically designed to handle various digital input signals, including TTL, CMOS, and voltage levels commonly used in industrial environments
