Panel meters are devices that measure electrical values, such as voltage, current, power, frequency, and resistance. Counters, hour meters, and totalizers are all specialized panel meters with unique applications and working principles.

One type of specialized panel meter is the 84093-01 counter. This counter is used for counter frequency and has two input circuits to provide pulse outputs. It\'s digital display enables user to read frequency easily and accurately. The 84093-01 operates on a 5-24VDC power supply and displays up to eight digits in a wide viewing angle.

The 84093-01 can measure frequency for signals between 20-6000Hz. Its input impedance is 20k ohms and the output impedance is 50 ohms. It features overload protection that will disconnect the input when overload occurs. The counter also includes a reset switch to restart the counting from zero.

The 84093-01 is highly effective for various applications, such as water measurement for chemical plant, condensate measurement for steam systems, power plants, or fire-fighting systems. This counter can also be used for flow counting and totalizing in industrial settings or monitoring of cycle times in production lines.

The working principle of the 84093-01 is quite simple. A digital input is connected to the input terminals and when a signal is applied to the terminal, the 84093-01 starts counting the signals. With each pulse, the counter increments or decrements the digital display. The 84093-01 stops counting at the maximum or minimum count points depending on its counting direction. It can operate in either up counter or down counter mode.

The reset switch is used to reset the counter to zero, while the power supply is used to power the unit. The overload protection feature will disconnect the power to the input when an overload is detected, thus preventing damage to the device.

The 84093-01 is an versatile and reliable device for use in frequency counting applications. It is easy to install, use, and program, and is well suited for applications in both industrial and commercial settings. Its digital display and adjustable counting direction make it a perfect choice for a variety of needs.
