Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry

Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level

Temperature indicators and temperature instruments are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input

Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms

Programmable automation controller (PAC) modules are add-on devices that perform a specific control function in PAC systems

Programmable automation controller (PAC) systems consist of PAC modules, each of which performs a specific function. PAC systems are used in motion control, machine control, machine vision, and other industrial control applications

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control. PACs are functionally similar to programmable logic controllers (PLC), but provide the advanced software features of personal computers (PC

pH and ORP controllers monitor and can control the pH (acidity or alkalinity) and/or the ORP (oxidation reduction potential) of liquids involved in a testing or process application

Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values

Machine controllers and monitors use electronic numeric control and monitoring interfaces for programming and calibrating computerized machinery

HVAC controllers are used to monitor and control heating, ventilation and air conditioning (HVAC) systems in buildings. They monitor indoor environmental factors such as temperature and humidity, and control heating and cooling to maintain desired levels

Environmental controllers control environmental factors such as temperature, humidity, and air pressure. The environment to control can be an office or workspace, or inside a chamber for testing or process purposes

Boiler controllers monitor and maintain variables such as steam temperature and pressure in order to control a boiler’s burner or air mixture

Furnace controllers are used to control temperature, heat delivery, and other variables in industrial furnaces. They control the burner flame, air mixture and trim to maintain and optimize furnace performance

Laboratory controllers are designed specifically to monitor and/or control variables involved in laboratory or scientific experimentation, testing, or sample preparation. They are often used to control temperature, but may also control other variables
