Pre-Set Timer

Annpab Technologies offers a 3-digit Pre-Set Timer, PTW03. This is a micro controller based 3-digit pre-set timer which accepts input pulses from proximity sensors or potential free contacts in the range of 5-30 V DC to start and stop the timer. With the elapsed time set on the thumb wheel, the timer counts down and switches an internal relay On with its COM-NO-NC contacts (potential free) available for external control of load. Various options settable from the front panel control the relay switching. The PTW03 is feature packed and addresses most of the application needs sought for in this product category, which was hitherto not provided by any single competitive model. Good quality components, CNC drilled glass epoxy PCB with solder mask, high quality ABS enclosure, use of large size thumb wheel switches, wide input voltage range switched mode power supply, etc., makes the product extremely reliable even under harsh industrial environments. The PTW03 sets a benchmark in industrial timers for its reliability, features, aesthetics and pricing. The PTW03 is very easy to wire-up and to configure at the shop floor.
