Industrial Computer - Overview
IPC (Industrial Personal Computer) is different than a regular PC because of its environmental characteristics. It’s shock absorption, moisture resistant, dust/water resistant, wide range working temperatures, anti-electromagnetic interferences, and its ease of access for expansion slots make it relatively robust. Designed for control platforms to operate in rigorous and harsh environments, IPC achieves industrial requirements for long term reliability and stability control platforms.
What is a Backplane?
A backplane (or "backplane system") is a circuit board (usually a printed circuit board) that connects several connectors in parallel to each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus. It is used as a backbone to connect several printed circuit boards together to make up a complete computer system. A backplane is generally differentiated from a motherboard by the lack of on-board processing power where the CPU is on a plug-in card. Backplanes are normally used in preference to cables because of their greater reliability. In a cabled system, the cables need to be flexed every time that a card is added to or removed from the system; and this flexing eventually causes mechanical failures. A backplane does not suffer from this problem, so its service life is limited only by the longevity of its connectors. Backplanes have grown in complexity from the simple ISA or S-100 style where all the connectors were connected to a common bus. Because of limitations inherent in the PCI specification for driving slots, backplanes are now offered as passive and active. Passive backplanes offer no active bus driving circuitry. Any desired arbitration logic is placed on the daughter cards. Active backplanes include chips which buffer the various signals to the slots.
Expansion Slots - Half and Full Size Slots
An Expansion Slot is an opening in a computer where a circuit board can be inserted to add new capabilities to the computer. Nearly all personal computers except portables contain expansion slots for adding more memory, graphics capabilities, and support for special devices. The boards inserted into the expansion slots are called expansion boards, expansion cards, cards, add-ins, and add-ons. Expansion slots for PCs come in two basic sizes: half- and full-size. Half-size slots are also called 8-bit slots because they can transfer 8 bits at a time. Full-size slots are sometimes called 16-bit slots. In addition, modern PCs include PCI slots for expansion boards that connect directly to the PCI bus.
Understanding the 80 PLUS® Certified Power Supplies
Power supplies absorb AC power (alternating currents) from a wall while transforming it into DC power (direct current). However, power can be lost during the transformation and drained as heat. This is where the 80 PLUS can become so beneficial. Overheating can become a major problem for computer system failure. Too much heat in power supplies demeans its reliability. But in order to reduce heat, 80 PLUS power supplies can increase a computer’s reliability up to 40% according to the Power Electronics Strategies. These power supplies decrease the demand for loud computer fans and lower electric bills in the long run. 80 PLUS certification is given to power supply models that meet an energy efficiency minimum. In order to have certification, these power supplies need to be at 80 percent efficiency, however, the power supply’s efficiency is different towards different loads. 80 PLUS provides Bronze, Silver, Gold, and Platinum levels.
