10-Year Data Retention & High Reliability：This 6-digit digital counter relay uses high-accuracy MCU control with EEPROM memory, preserving critical count values for up to 10 years—essential for applications where counting precision and reliability cannot be compromised.
Flexible Preset Scale & Counting Direction：The programmable preset counter provides an intuitive scale range and supports both UP and DOWN counting modes, allowing fast customization for batch counting, length measurement, and totalizing across diverse industrial processes.
Key Lock Function to Prevent Misoperation：A front-panel key lock secures all settings from accidental changes, reducing operational errors and improving productivity in demanding workshop environments.
Energy-Efficient Low Power Design：Engineered for continuous duty, the low power consumption design minimizes heat buildup inside control panels and helps reduce long-term energy costs.
Universal NPN/PNP Switchable Input：Versatile input accepts contact and non-voltage signals with simple NPN/PNP switching, enabling seamless connection to encoders, proximity sensors, and PLCs without external converters.
DIN Standard Panel Mount：Compact 48x48mm housing with 45x45mm cutout size, designed for flush installation in industrial control panels.
Wide Counting Range & High Speed：Count range from 1 to 999999. Supports UP/DOWN counting modes with a maximum counting speed of 10 kcps. Preset scale range adjustable from 0.001 to 99.999 for precise batch control.
MCU Digital Control with 10-Year Data Retention：High-precision microcontroller ensures reliable counting accuracy. Built-in EEPROM memory retains count data for up to 10 years, with user-selectable save option.
Versatile NPN/PNP Switchable Input：Input supports both contact/non-voltage (NPN) and voltage (PNP) signals with simple switching. Accepts control signals (Reset, Gate) with minimum pulse width ≥5ms. External DC 12V/50mA supply available for sensor excitation.
Clear Anti-Glare LED Display：PV (Present Value): 6-digit 9.2mm high-brightness red LED. SV (Set Value): 6-digit 7.0mm high-brightness green LED. Anti-glare panel ensures excellent visibility in bright environments.
Easy Operation with Key Lock：Tact switches for UP/DOWN setting value adjustment. Key lock function prevents accidental setting changes and power supply misoperation, enhancing on-site productivity.
Energy-Efficient Design：Low power consumption design minimizes heat generation inside control cabinets, suitable for continuous operation applications.
