Digital Automatic Sequence Timer Demonstration Unit ( with 4 Timer ) 2005

Categories: Industrial & Power Electronics


ADTRON’S Digital Automatic Sequence Timer Demonstration Unit is a versatile self – contained stand – alone unit, useful in the study and demonstration of the principle and working of a digital automatic sequence timer. It consists of four identical but independent solid state IC based crystal controlled time delay circuits with independently adjustable delay through two ten position coded push – button switches in 99 distinct steps. A change over relay contact of 230V, 5A for each timer is provided for external load. Programming of timers in any sequence is possible. The trainer is enclosed in a specially designed laser’s friendly elegant powder coated metal cabinet with intelligently designed layout on imported acrylic sheet.
