Electrical & Physical Specifications

Input Signal Processing & Fieldbus Architecture

The internal microcontroller executes dual-stage count comparison and tachometer frequency sampling with deterministic hardware execution. Onboard EEPROM memory guarantees firmware flash compatibility and preserves operational parameters during system supply power loss without auxiliary batteries. High-speed solid-state switching outputs allow fast status reporting to programmable controllers operating across Profinet and EtherNet/IP deterministic networks via external gateway couplers.

Package Manifest & Kit Items

• 1 x Omron H7CX-AWSD1-N Digital Counter/Tachometer Unit
• 1 x Flush Panel Mounting Adapter Clamp
• 1 x Waterproof Rubber Packing Ring
• 1 x Protective Terminal Cover
• 1 x Technical Instruction Sheet

Cabinet Installation & Field Wiring Procedures

• Panel Cutout Mounting

  Punch a standard 45 x 45 mm square cutout in the enclosure door. Position the rubber seal over the front housing bezel, push the instrument into the cutout, and slide the rear adapter bracket until locked.

• Terminal Block Connection

  Connect field leads directly to the rear M3.5 screw terminals. Maintain correct polarity on 12-24 VDC / 24 VAC supply line connections and open-collector output transistor leads.

• Noise Immunity & Shielding

  Route high-speed pulse sensor wires in grounded metallic conduits away from AC power lines and drive motor cables. Connect cable shields to a single panel grounding point to suppress electrical interference.

Frequently Asked Questions

• What supply voltage range is compatible with the H7CX-AWSD1-N?

  The unit runs on 12 to 24 VDC or 24 VAC at 50/60 Hz, operating reliably between 85% and 110% of rated supply voltage.

• How does 2-stage preset switching function on this model?

  The 2-stage configuration provides two independent setpoint stages to trigger sequential speed or count control outputs.

• What control output switching hardware is integrated into the unit?

  The unit utilizes NPN open-collector transistor outputs rated for up to 30 VDC and a maximum switching current of 100 mA.

• What physical wiring interface is present on the rear panel?

  Field wiring attaches directly to integrated M3.5 screw terminals protected by a rear terminal cover.

• How many digits are available on the front panel display?

  The backlit negative transmissive LCD panel provides a 6-digit display capacity covering a readout range from 0 to 999999.

• How are setpoint values retained during a DC supply outage?

  All setup values and current count registers are saved automatically to internal non-volatile EEPROM memory without battery backup.

• Can the input terminals process both NPN and PNP sensor signals?

  Yes, the input circuit supports NPN open-collector and PNP voltage input signals, configurable through internal settings.

• What cutout size is required for flush panel mounting?

  The device fits into a standard DIN 45 x 45 mm square panel cutout and locks in place with the rear mounting adapter.
