Vorne Industries 77256M-12S-00-3 Digital Display Readout

The Vorne Industries 77256M-12S-00-3 Digital Display Readout is a 3-digit LED event counter designed for real-time production monitoring in industrial environments. It supports up to 3,000 CPM in low-speed mode, with an optional high-speed count rate of up to 100,000 CPM, and uses sinking TTL/CMOS-compatible inputs, including contact closures or open-collector NPN wiring. Powered from 120 VAC ±15% and up to 15 VA, the unit features EEPROM non-volatile memory to retain counts during power loss without a battery backup, and it displays counts on a 3.3-inch-high LED digit display. Part of the 77/256M Series, it is designed for panel or enclosure mounting and is suitable for manufacturing lines, packaging equipment, and automation systems requiring real-time count display and production visibility. Commonly used by maintenance teams, OEMs, plant engineers, and system integrators for replacement, retrofit, or production-monitoring upgrades to improve operator awareness and process tracking. Auxiliary output options provide 5 VDC or 12 VDC at 100 mA for signaling, and the product is commonly installed in industrial production monitoring systems and process displays. Common replacements include Vorne 77256M-12S-00-4, 77256M-12S-00-5, and the XL400 Production Monitoring Display System.
