This adaptability ensures that the board can be seamlessly integrated into a variety of operational environments, enhancing its utility across various industries. The board plays a crucial role within control system architectures, contributing to the seamless functioning of simplex and triple redundant systems. When utilized within a simplex architecture, it often collaborates with a control module, collectively enabling the system to execute tasks with precision and efficiency. In this scenario, the board's capabilities enhance the overall performance of the control module, ensuring reliable and optimized operations. In TMR configurations, the board takes on a more extensive role, aligning with an IONet and a main processor card in addition to the control module. This expanded integration facilitates a robust and resilient control system capable of mitigating potential failures through redundancy.

Features

• On the board, there are a total of twenty-five metal oxide varistors. The board also includes two three-pin female plug connectors.
• This circuit board can be installed in a VME slot-type rack with thirteen or twenty-one slots. When used in a simplex architecture type system, it will typically be used with a control module, but if the chosen architecture is triple redundant, it will be used with an IONet, main processor card, and the control module.
  The TNCI model can be used with two types of communication: the Unit Data Highway, which is an Ethernet-based LAN type of communication, and the IONet communication. The UDH communication driver is usually associated with the main processor card.
• While the board contains a number of capacitors, resistors, and other small components, the main visual components of this model are the two terminal blocks, three sub-D pin connectors, two female plug-type connectors, and the twenty-five metal oxide varistors. The two terminal blocks, labeled TB1 and TB2, are located near the board's bottom edge, and the metal oxide varistors are located just above the two terminal blocks. Each of the three sub-D pin connectors, which are located near the top edge of the board, has 37 pins.

System Features

• A streamlined system architecture is needed for speed control systems for tiny turbines. The usage of simplex control helps to save money and space. The bigger T-type terminal boards used in TMR systems can be replaced by smaller DIN-rail mounted terminal boards. Since the D-type terminal boards directly connect to the control chassis to communicate with the I/O boards, IONet is not required.
• A VCMI board in the VME rack enables two-way communication between the I/O processor boards and the controller. Other system elements, like an operator interface or PLC, are communicated with using the controller's Ethernet port. The controller Genius port can be used to connect additional PLC I/O to the system.
• The system employs a low voltage variant of the common VME rack power supply and is powered by 24 V dc. The number of inputs and outputs, as well as the grounding facilities, are different, and the boards do not support TMR, but the signal conditioning on the DIN-type terminal boards is always the same as on the T-type boards, and the I/O standards stated above apply.
• Space is conserved by using high-density Euro-Block terminal blocks that are permanently mounted. The connectors on the blocks can accommodate up to two or one 12 gauge wires. The most common wire size is 18

Product Attributes

Communication Types

• UDH (Universal Data Highway) or IONet (Input/Output Network): These communication types facilitate seamless data transmission and exchange within the system. UDH offers a versatile data highway, while IONet provides an efficient input/output network, each serving specific functionalities and adaptability.

Characteristics

• Signal Integration: Turbine control systems often involve multiple sensors and switches that provide essential feedback and control inputs. These may include signals from temperature sensors, pressure sensors, flow meters, safety switches, or emergency stop buttons. The Contact Input DIN-Rail Module is used to collect these signals and bring them into the control system for monitoring and decision-making.
• Protection and Isolation: These modules typically offer electrical isolation and protection to prevent electrical interference and ensure the safety of the control system. Turbine environments can be electrically noisy, and isolation helps ensure that unwanted signals or electrical disturbances do not impact the control system's operation.
• Signal Processing: The module may also perform basic signal processing functions, such as debouncing switches, converting analog signals to digital formats, or scaling input values to the desired range for further processing. This processing is essential for ensuring that the signals are in a suitable format for control algorithms.
• Status Indication: Many Contact Input DIN-Rail Modules provide visual or remote status indications to inform operators or the central control system about the condition of the inputs. This is crucial for quickly identifying any issues or safety concerns.
• Communication and Integration: Some modules may have communication capabilities, allowing them to transmit the input data to the main turbine control system. This integration enables real-time monitoring and control, allowing operators to make informed decisions based on the inputs received.
• Fault Detection and Safety: The modules can be programmed to detect fault conditions or safety-critical events. For example, if a safety switch is triggered or if sensor values go beyond acceptable limits, the module can initiate emergency shutdown procedures or trigger alarms to ensure the safety of the turbine and the surrounding environment.
