Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions

Counter and timer boards are computer cards that perform digital counting and/or timing functions

Time delay relays and solid state timers use solid state electronic devices to provide a time delay

Electromechanical counters and electromechanical timers accept inputs to operate mechanical display, such as rotating wheels or knobs

IC timers are semiconductor circuits that generate or set timing for electronics circuits

IC phase-locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator.

Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency. Quartz, a piezoelectric crystal that provides excellent mechanical and electrical stability, acquires a charge when compressed, twisted, or distorted.

Flip-flops are digital logic devices that synchronize changes in output state (1 or 0) according to a clocked input.

Monostable multivibrators, also known as one-shots, are digital devices similar to flip-flops, but with only one stable state where they remain until triggered by an input signal. Once triggered, the output is switched to the opposite state.

Test equipment and instrument repair services test and repair industrial equipment and instruments. They specialize in the test and repair of acoustic and vibration equipment, electrical and electronic test equipment, laboratory equipment and instruments, inspection instruments or non-destructive testing (NDT) equipment, or specialty testing equipment and instruments.

Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications.

Microcontrollers (MCU) are complete computer systems on a chip. They combine an arithmetic logic unit (ALU), memory, timer/counters, serial port, input/output (I/O) ports and a clock oscillator

Test equipment and instrument rental services rent or lease test equipment for electrical, electronic, vibration, acoustic, dimensional, NDT, analytical, environmental, process, EMI/RFI, and other specialty testing, measurement or inspection applications.

Data acquisition I/O modules or cards have both input and output functionality. Digital or discrete I/O modules include on-off signals used in communication, user interface, or control.

Digital counters are integrated circuits used for counting events in computers and other digital systems.
