SLN-44
The SLN-44 series is a DIN 48 x 48 electronic preset counter with a Blue STN LCD display with white backlight. The display is 6 digits dual layer, divided into Main display and Sub-display. The main display has a 10 x 5 mm figure size showing the count value and the Sub-display shows the preset values. Included in the display are Preset level indicators and Output indicators which can be toggled by a push of a button.
The SLN-44 series is available in 1 or 2 level preset or 1 level + Prewarn type which makes it an ideal counter for general counting or total/batching counting applications. It is 100-240V AC or 12-24V DC powered and has an external power supply of 12V DC for sensors.
The SLN-44 can count bidirectional (Quadrature), Add, Subtract or Add/Subtract and upon reaching the preset value/s, the built-in output relays are actuated.
Functional modes, Operation modes and Output modes are fully programmable with the menu driven display using the front panel buttons. It has a built-in EEPROM memory to avoid loss of count during sudden power cut.
This makes the SLN-44 Series the most versatile and functional preset counter even for the complicated applications such as packaging (batching), converting (prescale), cut-to-length (preset+prewarn) and many more.
