Pre-Set Counter

Annpab Technologies offers a 4-digit Pre-Set Counter, PCW04. This is a micro controller based pre-set counter, which accepts input pulses from proximity sensors or potential free contacts in the range of 5-30 V DC counting up to 9999. When the input pulse count equals the value set on the thumb wheel, it switches the 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 PCW04 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 PCW04 sets a benchmark in industrial counters for its reliability, features, aesthetics and pricing. The PCW04 is very easy to wire-up and to configure at the shop floor.
