Functional Description

IS230TURSH2C is an I/O Module designed and developed by GE. It is a part of GE Mark VIe series. It supports DIN-rail mounting, enabling secure, space-efficient, and modular installation within control panels or enclosures. This standard mounting method simplifies installation and maintenance while ensuring compatibility with the system.

Modular Architecture

• Each Mark VIe I/O module is composed of three primary components: the terminal board, the terminal block, and the I/O pack. These elements work together to facilitate reliable signal acquisition, conditioning, and data communication between field devices and the control system.
• The terminal board is physically mounted to the control cabinet and is responsible for interfacing directly with field wiring. Mark VIe systems offer two types of terminal boards: S-type and T-type. The S-type terminal board provides a single set of screw terminals for each I/O point and supports the connection of a single I/O pack, which handles the conditioning and digitization of signals. This configuration is suitable for simplex, dual, or dedicated triple modular redundant (TMR) systems. In redundant configurations, one, two, or three S-type boards are used respectively to support multiple I/O packs.
• In contrast, the T-type terminal board is specifically designed for TMR architectures. It distributes, or “fans out,” the incoming signals to three independent I/O packs, enhancing system redundancy and fault tolerance. The T-type configuration also incorporates hardware-level voting mechanisms for output signals, allowing the system to determine the most reliable output based on inputs from all three I/O packs. This approach significantly increases reliability and is critical for safety-related or mission-critical control processes.

FREQUENTLY ASKED QUESTIONS

What is IS230TURSH2C?
It is an I/O Module developed by GE.

What is the difference between S-type and T-type terminal boards?
S-type boards connect a single I/O pack and are suitable for simplex, dual, or triple modular redundant (TMR) configurations using 1, 2, or 3 boards. T-type boards are used in TMR systems and fan inputs to three I/O packs. They typically perform hardware-level output voting for added reliability.

What type of mounting does it use?
It uses DIN-rail mounting, a standard method in control panels that supports secure and organized installation while allowing for easy maintenance.
