1 Purpose and functions The device is a universal counter that can be used for a wide range of automation tasks. It is designed to count the number of pulses coming to its inputs in direct and opposite direction and to convert further this number into a physical value (using multiplication by given multiplier). The device can perform following functions:
• count-up, count-down, reversing and other types of counting pulses from the connected sensors; • determination of the direction of rotational motion of units and mechanisms; • converting the number of pulses into real units of measurement; • powering sensors from the built-in 24 V DC power source; • load control by two built-in outputs; • saving counting results when power is turned off; • connection to PC via embedded RS-485 and USB interfaces. 2 Specifications and operating conditions 2.1 Specifications Main specification of the device is given in Table 2.1 .
