PRODUCT DESCRIPTION
Key Technical Features
-
Seamless NPN Logic Compatibility
Designed for 0V low-level valid (NPN/Source) logic, this 16-channel module seamlessly integrates 2-wire/3-wire sensors and dry contacts. Its high-density design saves valuable DIN-rail space while perfectly matching systems that rely on ground-switching logic, significantly simplifying wiring and reducing spare parts inventory.
-
Built-in 32-Bit Independent Counters
Beyond basic discrete inputs, all 16 channels feature built-in, customizable 32-bit counters (up to 200Hz). This cost-saving innovation allows you to track packaging counts or low-frequency flow meters without purchasing expensive dedicated counter modules, dramatically maximizing your system's return on investment.
-
Robust Isolation & Signal Filtering
Featuring optocoupler isolation, it protects your control core from industrial electrical noise and surges. Configurable signal filtering and holding times easily eliminate mechanical switch bounce and capture rapid pulses, while 16 LED indicators provide intuitive diagnostics for effortless on-site troubleshooting and maintenance.
