Product Description:
Danaher produces the 0799808-312 LCD timer/counter with eight decades of display. It has an inbuilt lithium battery and can be reset remotely. Applications requiring precise counting or timing over long periods of time are well-suited to the device.
The 0799808-312 LCD timer can run normally for up to ten years on a ten-year lithium battery. An eight-digit display is shown by the 0.2-inch (5.1 mm) LCD. An isolated switch with a 50 ms minimum contact closure is required to enable remote reset via pin 3, which is connected to a slide-on terminal. The voltage range that the count input can handle for AC/DC models is 6 to 250 VAC/VDC. The maximum speed that the timer can support at 50 Hz is 3000 counts per minute. With AC, a minimum on-time of 10 ms is necessary, while with DC, it is 7 ms. Both AC and DC have a minimum off-time of 10 ms and 9 ms, respectively. Both the standard and the switch variants are limited to a maximum count speed of 3000 cpm. The open or closed state needs to be maintained for at least 10 milliseconds, and the contact burden is 3 VDC at 500 µA. The transparent polycarbonate crystal and black modified polyphenylene enclosure were both chosen for their structural stability in automation applications.
Installation in normal control situations is supported by the 0799808-312 timer 's operating temperature range of 32°F to 122°F (0°C to 50°C). Rear pins measuring 1.6 mm in diameter are used for the connectors to guarantee a constant contact. When AC/DC input compatibility and remote reset are critical in industrial automation processes, this timer is utilized. With its standardized integration, extended operational life, and remote capability, the timer is an efficient choice.
