Functional Description

IS230TICIH1A is an Isolated Contact Input Assembly manufactured and designed by General Electric. It is a part of the Mark VIe Control System. Its flexible wiring and connectivity options ensure ease of installation and maintenance, while its point isolation and voltage detection circuits guarantee precise and reliable operation.

Point Isolation and Voltage Detection

• Features a Contact Input with Point Isolation (TICI) terminal board, which provides 24 isolated voltage detection circuits. These circuits are capable of sensing a wide range of voltages across relay contacts, fuses, and switches.
• This feature allows the module to isolate individual inputs, ensuring that each point can operate independently without electrical interference from other signals in the system.
• This isolation helps prevent unwanted signal cross-talk and improves the overall reliability and accuracy of the system.

Wiring Configuration

• Allows for straightforward wiring connections for the 24 isolated digital inputs. These wires are directly connected to two I/O terminal blocks on the terminal board. The blocks are secured with two screws for a solid and secure connection, and they can be easily unplugged for maintenance, ensuring minimal downtime during service. Each terminal block contains 24 individual terminals that can accept wire sizes up to #12 AWG.
• Additionally, the module includes a shield terminal strip that is attached to the chassis ground, providing a grounding point for the shielded wiring. This helps to reduce electrical noise and improve the stability of the signals, especially in environments with high electromagnetic interference. The shield terminal is located immediately to the left of each terminal block, ensuring easy access for proper grounding.

Cabling and Connectivity

• Offers flexible cabling options, supporting both simplex and TMR (Triple Modular Redundancy) system configurations. In a simplex system, the TICI module is connected to the I/O processor using connector JR1. This is suitable for applications where redundancy is not a high priority.
• For applications requiring higher reliability and fault tolerance, such as critical industrial systems, the TICI module can be connected in a TMR system using connectors JR1, JS1, and JT1.
• The TMR configuration ensures that the system can continue to operate even if one of the I/O processors fails, providing continuous monitoring and control. Depending on the specific type of Mark VI or Mark VIe control system being used, either cables or I/O packs are plugged in to complete the connection. The level of redundancy depends on the configuration and system requirements.
