A programmable load is a type of test equipment or instrument which emulates DC or AC resistance loads normally required to perform functional tests of batteries, power supplies or solar cells.
A PLC is an industrial microprocessor-based controller with programmable memory used to store program instructions and various functions. [21] It consists of: A processor unit (CPU) which interprets inputs, executes the control program stored in memory and sends output signals, A power supply unit which converts AC voltage to DC,
Ladder logic is widely used to program PLCs, where sequential control of a process or manufacturing operation is required. Ladder logic is useful for simple but critical control systems or for reworking old hardwired relay circuits. As programmable logic controllers became more sophisticated it has also been used in very complex automation systems.
An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections.
A simplified PAL device. The programmable elements (shown as a fuse) connect both the true and complemented inputs to the AND gates. These AND gates, also known as product terms, are ORed together to form a sum-of-products logic array. A programmable logic device (PLD) is an electronic component used to build reconfigurable digital circuits.
Phase-fired control (PFC), also called phase cutting or phase-angle control, is a method for power limiting, applied to AC voltages. [1] It works by modulating a thyristor , SCR , triac , thyratron , or other such gated diode -like devices into and out of conduction at a predetermined phase angle of the applied waveform.
A complex programmable logic device (CPLD) is a programmable logic device with complexity between that of PALs and FPGAs, and architectural features of both. The main building block of the CPLD is a macrocell , which contains logic implementing disjunctive normal form expressions and more specialized logic operations.
In 1986, GE Fanuc Automation Corporation was jointly established in the US by FANUC and General Electric (GE). Under the joint venture company, three operating companies, GE Fanuc Automation North America, Inc., in the U.S., GE Fanuc Automation Europe S.A. in Luxembourg, and Fanuc GE Automation Asia Ltd. in Japan were established (the Asian company was established in 1987).
