Electronic Counters and Electronic Timers

Electronic counters and timers are completely electronic units with a variety of features and functions; they may be programmable via computer interface.  Electronic counters and electronic timers can be single or multi function units.  Electronic counting functions may include: mathematical operations, control functions, batch counting, totalizing, event counting, preset or predetermining counting, pulse counting, up/down/bi-directional counting, frequency counting, or position indication.  Electronic timer functions may include: time indication (such as in time meters and clocks), and rate indication (such as tachometers).

Counters are complete instruments for detecting, totalizing, and indicating a sequence of events.  They may be mechanical, electromechanical or electronic devices, which can keep track of the number of input signals or pulses.  Timers are used for automatically starting, or stopping, a machine or other devices.  Counter / timer combinations can perform both counting and timing functions.  Electronic counters and electronic timers can be either single function or multi function, or programmable for more than one function.  Electrical counters and electrical timers can be up direction, down direction, or bi-directional.  Up directional counters can advance forward (UP) in its counting sequence.  Down directional counters can advance backward (DOWN) in its counting sequence.  A bi-directional counter can advance forward or backward (UP or DOWN) in its counting sequence.

Electrical counters and electrical timers can have many different functions.  These include arithmetic functions, controller, batch counter, count totalizer, event counter, preset, pulse counter, delay cycle, delay on timer, delay off timer, one shot timers, interval delay timer, recycle timer or percentage timer, frequency counter, position indicator, ratemeters or tachometers, and time meters or indicators (clocks).  Resets can be none, manual, remote, or auto reset.

Number of time ranges on electrical counters and electrical timers are single or multiple.  Single time ranges may be fixed or programmable.  Timers with multiple time ranges can be programmed for multiple ranges.  A minimum and maximum time setting must also be specified.  Mounting types include stand-alone, DIN rail mount, panel or flange mount, PCB mount, portable, and rack mount.
