IC timers are semiconductor circuits that generate or set timing for electronics circuits. Learn More about IC Timers
Inches, 2.30 Inches, and 2.50 inches. A circuit timing device is built with IC’s and some other components on a PCB. The timing modes and delay ranges are selected by on-board DIP switches. A few examples of other IC timers are the 555, 556, 558... Learn More about Specialty IC Timing Devices
Flip-flops are digital logic devices that synchronize changes in output state (1 or 0) according to a clocked input. Search by Specification | Learn More about Flip-flops
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. Learn More about Phase-locked Loops (PLLs)
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. Search by Specification | Learn More about Crystals
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. Search by Specification | Learn More about Monostable Multivibrators
Counter and timer boards are computer cards that perform digital counting and/or timing functions. Search by Specification | Learn More about Counter and Timer Boards
Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions. Search by Specification | Learn More about Electronic Counters and Electronic Timers
Time delay relays and solid state timers use solid state electronic devices to provide a time delay. Search by Specification | Learn More about Time Delay Relays and Solid State Timers
Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs. Search by Specification | Learn More about Oscillators
Electromechanical counters and electromechanical timers accept inputs to operate mechanical display, such as rotating wheels or knobs. Search by Specification | Learn More about Electromechanical Counters and Electromechanical Timers
Specialty timers are specialty or proprietary products related to timers and timing devices. Learn More about Specialty Timers
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. Search by Specification | Learn More about Mechanical Timers
Delay lines are devices used to slow down a signal by a time interval in an electrical network. There are two basic delay line technologies: passive and active. Search by Specification | Learn More about Delay Lines
Phase-locked loop (PLL) frequency synthesizers are electronic devices that produce frequencies coherent to a reference frequency. Search by Specification | Learn More about PLL Frequency Synthesizers

The TAC4 is a bypass timer that provides a closure across the low pressure switch during compressor startup.
Its time delay circuit is totally solid state including the normally closed output. The molded housing with
encapsulation, the single hole mounting, and 0.25 in. (6.35 mm) termination makes the TAC4 easy to use,
rugged, and reliable.
