Functional Description

IS230TNAIH4C is an analog I/O board developed by GE. It is a part of Mark VIe control system. The systems differ in several ways, the most obvious being that the Mark VI is a centralized control system based on a Central Control Module, whereas the Mark VIe is a distributed control system with nodal control modules under unified control. It is a DIN-rail-mountable Analog I/O card. The Mark VIe control was created to serve a wide range of control and protection applications, including steam and gas turbines, as well as power generation balance of plant (BoP) equipment. The control provides more redundancy options, improved maintainability, and increased capability for locating I/O closer to the controlled equipment. The control system is made up of three major components: controllers, I/O networks, and I/O modules.

Features

• This board has three PDIA packs connected to three 37 pin vertical connectors with latching fasteners (JR1/JS1/JT1). These discrete input packs serve as the electrical interface between up to two Ethernet networks and the input terminal board. A processor board with two independent 10/100 Ethernet ports and an internal temperature sensor is included in each pack.
• This board also includes a fast processor, RAM, and flash memory. Diagnostics are performed using the onboard LED indicator lights located at the top of each module.
• PDIA packs can be replaced without requiring manual reconfiguration; auto-reconfiguration should enable an automatic download from the controller to any new I/O pack.
• Two terminal strips screw mount to the board surface to populate the TNAIH4C. There are two 3-position plugs on the board. Several lines of capacitors, diodes, and resistors populate it. Twenty-five MOVs (metal oxide varistors) are used on the board to protect circuits from overvoltage conditions.
• The board is screw-mounted to a DIN-rail frame. These are created using pre-drilled holes and two oval cutouts in the board surface. The DIN rail extends beyond one edge and is equipped with a shield bar.

Product Attributes

• The analog inputs are designed to accept voltage or current signals from sensors, which can be used to measure physical parameters such as temperature, pressure, or flow. The inputs are configurable to accept different signal types and ranges, allowing them to be adapted to a wide variety of sensors.
• The analog outputs can be used to control actuators such as valves, motors, or heaters. The outputs are designed to provide a configurable voltage or current signal, allowing them to be adapted to the requirements of the specific actuator being controlled.
• The module also includes features such as overvoltage protection, isolation, and diagnostic capabilities, which help to ensure reliable and safe operation. The DIN-rail mounting design allows for easy installation and integration with other modules in a control system.

System Redundancy

• Dual redundant systems are available in single, dual, and triple sensor configurations. If a controller or power supply fails, their dual internal networks and controllers keep the process running. To protect against soft or partial failures of devices that continue to operate but with incorrect signals/data, triple redundant systems are available.
• With a 2-out-of-3 signal selection, these systems out vote a failed component.
• The application software in all three controllers is based on the signal's voted value, while diagnostics identify the failed device. These sophisticated diagnostics reduce mean-time-to-repair (MTTR), while on-line repair capability reduces mean-time-between-forced-outages (MTBO) (MTBFO). These systems can use single, dual, or triple field sensors. To separate the application software for different pieces of equipment, a second controller can be provided.
• A core engine control for an air-fuel governor, for example, can run in one controller, while auxiliary control can run in another.

System Features

• Mark VIe I/O modules share three components: a field wiring termination block, a terminal board, and an I/O pack (s). DIN rail mounting is used for the modules. Wide gauge wiring eliminates the need for marshalling and reduces costs.
• Each I/O pack includes two IONet ports as well as a local processor with a real-time clock synchronized for 1ms time-stamping in the sequence-of-events (SOE) function, which is available on all discrete inputs and outputs. Customers can use this feature to select SOE with the click of a button, eliminating the complexity and expense of dedicated SOE hardware. Pack-level I/O diagnostics and voting are carried out.
• TMR I/O modules have three I/O packs mounted to a common terminal board, whereas Simplex I/O modules have one I/O pack mounted on the terminal board. I/O redundancy is selected once during hardware configuration and is invisible to application code.

High-Speed Processor and Memory

• The board boasts a high-speed processor complemented by RAM and flash memory.
• This robust processing capability ensures rapid and efficient data handling within the control system.

Diagnostic LED Indicators

• Onboard LED indicator lights, positioned at the top of each module, facilitate diagnostics.
• These indicators provide visual feedback on the board's operational status, aiding in troubleshooting and maintenance.

Auto-Reconfiguration Capability

• The board supports auto-reconfiguration, allowing for the replacement of PDIA packs without manual reconfiguration.
• Auto-download functionality ensures a seamless transition and data transfer from the controller to any new I/O pack.
