A customer ordered a DC-Digital DC-40T-UP-TERM<\/a> large digital LED count-up timer configured for automatic operation with a diffused reflective sensor. The combination provides a simple way to measure and display the amount of time an object remains within a monitored area without requiring an operator to manually start and stop the timer.<\/p>\n\n\n\n

The DC-40T-UP-TERM<\/a> is designed to count elapsed time from hundredths of a second through 99 hours using Shift Digit Technology. With four-inch, super-bright red LED digits, the elapsed time can be viewed from distances of up to 200 feet, making the timer suitable for applications where the display needs to remain clearly visible from across a work area.<\/p>\n\n\n\n

For this application, the timer is controlled by a diffused reflective sensor. The sensor detects when an object is present and provides a PNP output to the timer. While the object remains detected, the PNP signal keeps the timer operating. When the object passes out of the sensor’s detection range, the PNP output is removed and the timer stops, leaving the accumulated elapsed time displayed.<\/p>\n\n\n\n

This automatic start-and-stop operation allows the DC-40T-UP-TERM<\/a> to track the duration of an event based directly on the presence of an object. Rather than requiring an operator to monitor the process and manually control the timer, the sensor provides the input that determines when timing begins and ends.<\/p>\n\n\n\n

The timer retains the accumulated time until a reset command is provided. Resetting can be performed locally or through an external control input, allowing the timer to be returned to zero before the next timing cycle. This makes the system useful for repetitive processes where elapsed time needs to be measured, displayed, recorded, and then reset for another cycle.<\/p>\n\n\n\n
