FUNCTIONAL DESCRIPTION:

IS230TICIH2A is a Contact Input with a Point Isolation Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The Contact Input with Point Isolation (TICI) terminal board provides 24-point isolated voltage detection circuits to sense a range of voltages across relay contacts, fuses, and switches. In 240 V ac applications, do not inadvertently cross-connect the 240 V ac and the dc voltages. The peak voltage will exceed the MOV rating failing. Most ac supplies operate with a grounded neutral, and if an inadvertent connection between the 125 V dc and the ac voltage is created, the sum of the ac peak voltage and the 125 V dc is applied to MOVs connected between dc and ground. However, in 120 V ac applications, the MOV rating can withstand the peak voltage without causing a failure.

INSTALLATION:

Connect the wires for the 24 isolated digital inputs directly to two I/O terminal blocks 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. In a simplex system, connect TICI to the VCCC board using connector JR1. In a TMR system, connect TICI to the VCs using connectors JR1, JS1, and JT1.

OPERATION:

• No contact excitation is provided on the terminal board.
• Each input is electrically isolated from all others and the active electronics.
• 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
• 16-32 V dc, nominal 24 V dc, with a detection threshold of 9.5 to 15 V dc

FREQUENTLY ASKED QUESTIONS:

How many input channels does the terminal board support for isolated voltage sensing?

The terminal board provides support for 24 input channels for isolated voltage sensing. This allows the monitoring of 24 separate voltage signals from relay contacts, fuses, switches, or other electrical components.

What is the acceptable input voltage range for the terminal board?

The terminal board operates with an input voltage range of 16 to 32 V DC, with a nominal voltage of 24 V DC. This range ensures compatibility with various DC power supply configurations commonly used in electrical systems.

How is the terminal board configured for operation?

The terminal board does not require any physical jumpers or hardware settings for its configuration. The absence of jumpers or hardware settings simplifies the setup process and reduces the chances of misconfigurations.
