The 898X is a counter, tachometer, timer and position display in a single unit. It can be used as a preset counter, batch counter or totalizer depending on  requirements, with automatic help text to take the user through programming. With its automatic help text, clearly and legibly displayed on 14 LED segments, the 898X preset counter takes the user effortlessly through the programming. The large user-friendly front keys can be operated even when wearing gloves. The 14mm high LED display ensures easy reading even from a long distance and in poor lighting conditions. 

Available with RS485 interface and MODBUS and CR/LF protocol
