Omron H7CX-AES-N H7CX Multifunction Counter/Tachometer

Description

Designed for high-precision industrial control, the Omron H7CX-AES-N is a standard-type, ultra-compact digital multifunction counter and tachometer. This highly versatile control module integrates multiple counting and speed-monitoring configurations into a single, space-saving unit, allowing systems engineers to standardize on a single component for various manufacturing line requirements. Featuring a highly legible 6-digit display, the device provides real-time process value (PV) and set value (SV) monitoring.

The Omron H7CX-AES-N utilizes a robust 1-stage preset limit configuration, delivering fast-response transistor output switching based on target batch counts, lengths, or rotational speeds. Equipped with secure screw terminals for direct field-wiring connections, this unit is engineered for reliable, continuous operation under varying supply voltages ranging from 100 to 240 VAC.

Features

• Dual-Function Modes: Operates seamlessly as either a high-speed preset counter or a precise digital tachometer.
• High-Visibility 6-Digit Display: Dynamic status monitoring with configurable color change displays to indicate set value matching.
• Flexible Signal Inputs: Supports multiple input modes including individual, phase-difference, and command inputs compatible with both NPN and PNP sensors.
• Integrated 1-Stage Presets: Easy-to-program single-stage switching output thresholds for precise process control.
• Screw Terminal Wiring: Standard mechanical terminal block ensures reliable, vibration-resistant electrical terminations.

Applications

• Batch counting and packaging lines
• Cut-to-length automation processes
• Conveyor speed monitoring and throughput tracking
• Rotational speed (RPM) indication on motor drives
• Automated assembly and positioning systems

Installation Guidelines

For optimum electrical noise immunity and safe deployment, observe the following engineering procedures:

• Panel Mounting: Ensure the mounting gasket is properly seated before securing the unit into the cutout to maintain the front panel IP66 environmental seal.
• Wiring Isolation: Route the high-voltage power supply lines (100 to 240 VAC) separately from low-voltage signal and sensor input lines to prevent electromagnetic interference.
• Sensor Shielding: Use shielded, twisted-pair cables for sensor input connections, terminating the shield to a dedicated system ground point.
• Tightening Torque: Secure the screw terminal connections using a maximum torque of 0.5 Nm to prevent damage to the internal terminal block threads.
