Programmable Counter, Timer, Ratio/Speed Indicator

Devanshi Electronics offers a range of stable, reliable and optically isolated micro controller based fully programmable counters, timers and speed/ratio indicators. These can accept universal inputs like NPN, PNP, IR sensors, proxy and encoder, etc. Counters are available in 6-digit single display or 6- and 4-digit dual display models. The user with programmable multiplying and dividing factors can scale input. Reverse/forward counting models up to 3 outputs are available, which are programmable with respect to various configurations of input and logic. In short it can be used as a small PLC for batching, counting, printing etc. The timers are 6-digit with programmable output like On delay, Off delay or cyclic (with equal/unequal time). Ranges are also programmable. These can be used in different modes like power on start, start with input, on till trigger is available etc. Specifications: sensor ? potential free contacts, proximity switch, voltage pulses, photo detector, IR sensor, magnetic switch, encoders, etc.; display ? 7-segment LED display; speed ? 2000 pulses/second (2 kHz); memory ? non volatile; settings ? keyboard; supply ? 230 V AC ?10% 50 Hz; dimension ? 96 x 96 x 110 mm/72 x 72 x 110 mm/48 x 48 x 110 mm; and cut out ? 92 x 92 mm/68 x 68 mm/44 x 44 mm.
