Digital counter with 2x4 digit LED display 48x48

The DS-48 is a programmable digital pulse counter designed for industrial automation and control applications. It allows for up, down, or bidirectional counting functions, with a configurable output upon reaching a preset value, making it an ideal solution for machinery, production lines, and positioning processes.

This device accepts signals from limit switches, proximity sensors, and incremental encoders , offering great integration flexibility thanks to its multiple operating modes and configuration options.

It features a dual 4-digit LED display that allows simultaneous viewing of the count value and the preset value, simplifying process adjustment and monitoring. Furthermore, it incorporates EEPROM memory that retains the counter's configuration and status even after a power outage.

The DS-48 offers 9 operating modes and 7 input types , adapting to a wide variety of counting and control applications. It also allows you to configure a calibration factor , select the decimal point position, add an offset value, and define the output as a timed pulse or latch.
