CT36 is a simple and low-cost battery-powered electronic counter, enclosed in a small plastic box with 48×24 mm front size. Equipped with a 8-digit LCD display, CT36 can count up to 99999999 units. It has 2 inputs – counting input with counting speed up to 1000 cps and a RESET input. Both inputs can accept input signals from mechanical or electronic switches. A RESET button on the front panel is also available. The device may be equipped with micros-witches allowing front frequency selection as well as front reset key enabling. CT36 is powered by an incorporated lithium battery that has approximately 7 years of life cycle. Thanks to its small size and long- life battery operation, CT36 can be very useful for many applications requiring independent supply and small mounting dimensions such as integration in water meters, gas meters, etc.
