Product Highlights

The SLE73 Indicator is a specialised meter designed for applications that require a gradual accumulation of impulses. With its dual entry ports, one for counting and another for programmable functions, the meter offers versatile functionality. Users can use the programmable function to reset the meter to zero, stop its operation, or even change its counting direction as needed. The built-in entry port divisor, which can be programmed with a value ranging from 1 to 9999, combined with an adjustable decimal point, allows for a straightforward conversion of incoming impulses into the desired units. Configuration of the counter can be easily done using the local keyboard or the user-friendly S-Config software, which is available free of charge. Furthermore, the meter supports RS-485 communication, enabling convenient connectivity for remote programming and control. The SLE73 Indicator provides a reliable and flexible solution for applications that require precise impulse counting.
