Configured for high-speed pulse processing and dual-stage limit control in industrial automation panels, the Omron H7CX-AW-N (H7CX-AW Multifunction Counter) provides direct physical/electrical execution.

Architectural Nomenclature & Model Structure

• H7CX: Omron 48 mm x 48 mm digital counter and tachometer series platform.
• A: Standard functional capability preset module.
• W: 2-stage preset switching control profile.
• Supply Voltage (None): High-voltage AC line power configuration (100 to 240 VAC at 50/60 Hz).
• Terminal Interface (None): Rear-panel M3.5 screw terminal block layout.
• Digits (None): 6-digit negative transmissive LCD display (-99999 to 999999 counting range).
• N: Enhanced architectural design suffix featuring updated front bezel contrast and shallow enclosure depth.

Electrical & Physical Specifications

Firmware Flash Compatibility & Internal Processing Logic

The high-speed digital core operates with real-time pulse accumulation up to 10 kHz input rates. Internal memory architectures enforce firmware flash compatibility across setting parameters, holding user scaling factors and setpoint thresholds in non-volatile EEPROM without battery assistance. Internal boot routines run integrity checksums across system registers during power initialization, isolating output control logic until internal DC supply buses reach stable operating thresholds.

Installation Directives & Cabinet Assembly

Panel Cutout & Mechanical Mounting

• Prepare a 45 mm x 45 mm square cutout in the enclosure door; fit the rubber gasket over the front bezel prior to insertion to maintain an IP66 water and dust seal.
• Push the unit into the cutout from the front and slide the rear mounting adapter clamp forward until it locks firmly against the inner panel door.

Field Wiring & Noise Isolation

• Attach field conductors to the rear M3.5 screw terminals using crimped ring or fork terminals; torque terminal screws to 0.5 N-m.
• Route pulse signal cables from proximity switches or rotary encoders in grounded shielded cables, keeping signal wiring separate from AC power conductors and VFD motor cables.

Technical Questions & Answers

• What does the W designation signify in the part number?

  The W code specifies a 2-stage preset configuration, permitting two independent control output setpoints during pulse accumulation.

• How are setpoint parameters maintained during complete AC supply loss?

  Internal EEPROM non-volatile memory retains all user-programmed parameters, limit setpoints, and current count states without battery power.

• What voltage range is accepted by the AC supply terminals?

  The instrument accepts line supply voltages from 100 to 240 VAC at 50/60 Hz.

• How is environmental protection achieved on panel installations?

  Installing the unit with the provided rubber sealing gasket maintains an IP66 equivalent dust-tight and water-resistant front interface.

• What display capability is provided on the front interface?

  The 6-digit negative transmissive LCD screen displays values from -99999 to 999999 with selectable decimal point positions.

• What switching outputs are available on the rear terminals?

  The instrument provides physical relay contact outputs along with solid-state transistor switching outputs for PLC signaling.

• Can the unit operate in tachometer or rate measuring modes?

  Yes, internal parameters allow selection between preset counter, totalizing counter, and tachometer frequency modes.

• What physical terminal style is integrated into the rear housing?

  The housing features standard M3.5 screw terminal blocks for direct wire connections without external socket bases.
