A. Product Overview

The Omron H7EC-N-B 8-Digit Self-Powered Total Counter is a compact digital totalizing counter used to count electrical pulses generated from industrial machines, sensors and control systems. It features an easy-to-read 8-digit LCD display and operates using internal battery power, making it suitable for applications where external power supply is unavailable or not required.

The counter is designed for long-term operation with high counting reliability and is commonly used in production lines, packaging machines, automation panels and industrial equipment where accurate event tracking is required.

Key Features:

• 8-digit LCD display for clear counting visibility
• Self-powered operation with built-in lithium battery
• High counting speed up to 1 kHz
• Compact panel mounting design
• Manual reset function
• Low power consumption
• Reliable pulse counting for industrial applications
• Suitable for machine cycle and production monitoring

B. Working Principle

The Omron H7EC-N-B works by receiving electrical pulse signals from connected devices such as proximity sensors, limit switches, photoelectric sensors or machine controllers.

Each incoming pulse represents one event or operation cycle. The counter detects these pulses and increases the displayed count value accordingly. The built-in battery powers the internal counting circuit and LCD display, allowing operation without an external power connection.

When the reset function is activated, the accumulated count value can be cleared and the counting process can start again.

C. Why It Is Used

The Omron H7EC-N-B total counter is used for monitoring and recording the number of operations performed by industrial machines and equipment.

Common reasons for using this counter include:

• Accurate production quantity measurement
• Machine cycle monitoring
• Preventive maintenance scheduling based on operating cycles
• Batch counting applications
• Tracking equipment usage
• Simple installation without additional power wiring
• Reliable counting in industrial environments

Its self-powered design makes it useful for standalone machines and systems where continuous external power supply is not available.
