Counters and industrial timers are used in a variety of applications including process timing, process control, and unit counting.
Counter and timer boards are computer cards that perform digital counting and/or timing functions.
Digital counters are electronic devices that perform a variety of counting functions. They may count single actions, provide totalizing, or perform other calculations.
Digital timers keep track of timing, either to trigger an action or to start timing once triggered by an action, or both.
Elapsed time indicators (also known as ETIs, elapsed time meters, and hour meters) indicate, monitor, and record durations of time. The most common ETI is the hour meter, which records elapsed time in hours.
Electromechanical counters are used to detect, totalize, and indicate a sequence of events. They typically accept electric or electronic inputs to operate mechanical outputs such as rotating wheels or knobs. These devices may count UP and/or DOWN, support multiple functions, and provide reset capabilities.
Electromechanical timers are used to start or stop a machine or other device at preset or delayed intervals. They consist of both electrical and mechanical components, and often feature an electric motor that drives one or more gears. They typically accept electric or electronic inputs to operate a mechanical output such as rotating wheels or knobs.
Mechanical counters are used to detect, totalize and indicate a sequence of events in applications that do not use electrical power.
Mechanical timers are used to actuate devices at the end of a specified time period. They do not require electrical power and can be stored for long periods of time.
Time delay relays and solid state timers use solid state electronic devices to provide a time delay.
