About This Product

Count Anything. See It Clearly.

Electromed's Jumbo Digital Counter is a versatile counting solution for industrial and commercial applications. It accepts Potential Free Contact, PNP, NPN sensor, and DC Pulse inputs without adapters, and lets you configure debounce time and minimum count interval to suit both high-speed and slow-pulse applications.

Available in five display sizes from 2" to 12" and digit configurations from 4D to 8D, it delivers clear visibility at any distance on the shop floor.

Supports Potential Free Contact, PNP, NPN sensors, and DC Pulse inputs.
Adjustable debounce time: 0–1000 ms.
Adjustable minimum time between counts: 0–600 seconds.
Compatible with 12–24 V DC signals.
Over-voltage and reverse polarity protection.
1000 V AC isolation between input and internal circuitry.
Power supply: 85–265 V AC.
Enclosure: MS powder-coated.
