A Programmable Logic Controller, PLC or Programmable Controller is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines or light fixtures. PLCs are used in many industries and machines.
PLCs are designed for multiple analogue and digital inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact.
Test and repair single and 3 phase motors.
ICSs are typically used in industries such as electrical, water, oil, gas and data. Based on data received from remote stations, automated or operator-driven supervisory commands can be pushed to remote station control devices, which are often referred to as field devices.
Field devices control local operations such as opening and closing valves and breakers, collecting data from sensor systems, and monitoring the local environment for alarm conditions.
Electrical equipment can become faulty and regular inspections and testing can reduce the chances of faulty equipment leading to a hazardous situation. Electrical equipment that is portable or frequently moved that is connected by a flexible cord to a power supply can often become faulty much quicker. Examples are kitchen
appliances, overhead projectors, lights/lamps, heaters, computers etc. Cord extension sets, electrical portable outlet devices (EPOD's/mulitboxes), flexible cords, portable isolation transformers and RCD's (portable type, socket outlet type) also require testing.
The main purposes of a Heating, Ventilation, and Air-Conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort.
The choice and design of the HVAC system can also affect many other high performance goals, including water consumption and acoustics.
