The product was ordered for applications where a speaker, presenter, or other participant needs an easy-to-see countdown display that automatically communicates when the scheduled time has been exceeded.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The timer counts down from a programmed value of up to 99 hours, 59 minutes and continues measuring time down to hundredths of a second. When the countdown reaches 00:00, the display changes to show a negative sign and continues counting upward. This provides a silent indication that the allotted time has expired without requiring an audible warning or verbal interruption. The flashing display further emphasizes that the speaker has moved into overtime.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/dc-digital.com\/store\/product683.html\" data-type=\"link\" data-id=\"https:\/\/dc-digital.com\/store\/product683.html\">DC-40T-DN-W-NEG<\/a> uses five super-bright red 7-segment LED digits with an actual digit height of 4 inches. The display can be viewed from distances of up to 200 feet, making it suitable for auditoriums, meeting rooms, classrooms, presentation areas, conference facilities, and other locations where the timer needs to remain visible while the speaker is facing the audience.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The included handheld wired remote provides direct control of the timer through a membrane switch pad connected by 25 feet of cable. The RJ-45 quick-connect design allows the remote to be connected conveniently to the display while keeping the operator&#8217;s controls separate from the main timer enclosure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Key operating functions include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Start and stop control for managing the countdown<\/li>\n\n\n\n<li>Reset to the previously programmed time value<\/li>\n\n\n\n<li>Reset to zero<\/li>\n\n\n\n<li>Hour, minute, and second adjustment<\/li>\n\n\n\n<li>Automatic negative-time display after reaching 00:00<\/li>\n\n\n\n<li>Continued count-up operation during overtime<\/li>\n\n\n\n<li>Retention of the last programmed value after power is removed<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The timer retains its last set value when power is disconnected, helping simplify repeated use when the same presentation or speaking duration is used regularly. The control functions also allow the operator to adjust the hours, minutes, and seconds as needed for different events or time limits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/dc-digital.com\/store\/product683.html\" data-type=\"link\" data-id=\"https:\/\/dc-digital.com\/store\/product683.html\">DC-40T-DN-W-NEG<\/a> is housed in a durable 14-gauge aluminum enclosure with a fingerprint-resistant black powder-coated finish. The standard enclosure measures 24-1\/2 inches wide by 7-3\/4 inches tall and 2-3\/8 inches deep, with slotted tear-drop mounting tabs for installation. NEMA 4X and aluminum IP66 enclosure options are also available for applications requiring additional environmental protection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The display operates from a 120\u2013240 VAC power source through the included PS-12-700 wall adapter with a 6-foot power cord. Its combination of large red LED digits, long viewing distance, dedicated handheld controls, and automatic overtime indication makes it particularly useful for situations where speakers need a simple and highly visible way to manage presentation time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/dc-digital.com\/store\/product683.html\" data-type=\"link\" data-id=\"https:\/\/dc-digital.com\/store\/product683.html\">DC-40T-DN-W-NEG<\/a> provides a practical timing solution for speech and presentation applications where the display needs to do more than simply reach zero. By automatically switching to a negative indication and counting upward after the allotted time has expired, the timer gives both the operator and speaker an immediate visual indication that the scheduled time has been exceeded.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Visit <a href=\"https:\/\/dc-digital.com\/store\/index.php\" data-type=\"link\" data-id=\"https:\/\/dc-digital.com\/store\/index.php\">DC-Digital website<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/dc-digital.com\/store\/contact-us.php\" data-type=\"link\" data-id=\"https:\/\/dc-digital.com\/store\/contact-us.php\">Contact us<\/a> to ask about our customized products!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>See product: DC-405T-DN-NEG-WR When a speaker needs to stay within a defined presentation or speech time, the DC-40T-DN-W-NEG countdown timer provides a clear visual way to monitor the remaining time and indicate when the allotted time has expired.
