FUNCTIONAL DESCRIPTION:

IS230TICIH4A 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 plug-in supporting a variety of system configurations.

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

• 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 Vrms, 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 a device used in electronic systems to connect digital signals from external sources to a central processing unit (CPU) or controller. It provides isolation between the external signals and the internal electronics to prevent damage from voltage spikes or electrical noise.

What are the benefits of using an Isolated Digital Input Terminal Board?

Isolation helps protect sensitive electronic components from damage caused by voltage spikes, ground loops, or electrical noise. It also enhances system reliability by ensuring accurate signal transmission and reducing the risk of signal interference.

How does isolation work in a Digital Input Terminal Board?

Isolation is typically achieved using optocouplers or galvanic isolation techniques. Optocouplers use light to transmit signals across a barrier, while galvanic isolation employs transformers or capacitors to block electrical currents.
