Особенности
- Time and pulse counters help to plan maintenance intervals and ensure high plant availability
- Versions without zero position and with electric or manual zero position for all applications
- Flexible application of the digital counters for power supplies of 12 to 150 V DC and 24 to 240 V AC in a single device.
Функции
Счетчики времени считают время в часах с точностью до двух знаков после запятой (сотая часть часа). Счетчики импульсов
суммируют количество импульсов, например, переключений устройств.
Электронные счетчики сохраняют результат измерений при исчезновении напряжения в течение неограниченного периода
времени (EEPROM). После возврата напряжения счет продолжается, начиная с сохраненного значения.
Схема подключения
Дальнейшая информация
Time counters count the time in hours with an accuracy of two decimal places (hundredths of hours). The pulse counter adds the number of pulses, e.g. the making operations of devices.
A power supply is required at terminals 1 and 3 of the electronic counters so that the device can constantly display the measured values. Once terminal 3 is supplied with voltage (for DC "+"), the counting procedure starts. If terminal 4 is supplied short-time with voltage (for DC "+"), the counter is reset.
In the case of electronic counters, the counting result is saved indefinitely in the event of a power failure (EEPROM). On recovery of the power, the counting is continued from the saved value. As well as a modern design, the electronic counter has a 7-digit LCD, which can be reset electrically or manually.
