Programmable Logic
Controller Solutions
The Programmable Logic Controller (PLC) is the workhorse of Industrial Control systems. It uses digital and analog I/O modules to interface to sensors, actuators and other equipment. These I/O modules must meet stringent electrical specifications and designers face challenges in conditioning and converting these signals.
Industrial Automation Solutions Sensors and Field Transmitters
Monitoring and maintaining process variables at the appropriate levels is extremely critical in industrial automation and process control. A sensor in the industrial environment is either continuously or periodically measuring vital parameters such as temperature, pressure, flow, etc. The primary challenge of sensing in industrial environments is conditioning low signal levels in the presence of high noise and high surge voltage.
Industrial Automation Solutions Human Machine Interface
Human Machine Interface (HMI), also referred to as User Interface, Operator Panel or Terminal, provides a means of controlling, monitoring, managing and/or visualizing device processes. Ranging from simple segmented displays to high-resolution LCD panels, HMIs can be located on the machine, in battery-operated, portable handheld devices, and also in
centralized control rooms.
Industrial Automation Solutions Industrial Communication
In today's industrial automation market new technology brings many opportunities for industrial system developers to successfully address ever-evolving challenges. With applications ranging from programmable logic controllers and industrial computers to human machine interface, industrial peripherals and factory communication, automation systems require cutting-edge technologies to meet stringent customer requirements for high reliability and harsh environment in mission-critical environments.
