Technical & Electrical Specifications

Deterministic Counting & Network Architecture Interfacing

The internal high-speed logic processor enables microsecond input pulse capture for accurate speed and count calculations. Integrated non-volatile EEPROM memory guarantees firmware flash compatibility and configuration parameter retention without battery power. High-density I/O routing allows immediate signal conversion, enabling real-time status reporting to programmable logic controllers across Profinet and EtherNet/IP deterministic networks via dedicated coupling modules.

Package Manifest & Kit Items

• 1 x Panel Mounting Adapter Clamp
• 1 x Waterproof Rubber Packing Ring
• 1 x Instruction Instruction Sheet

Cabinet Installation & Socket Wiring Instructions

• Panel Cutout & Insertion Prepare a standard 45 x 45 mm DIN panel cutout. Fit the rubber seal over the housing, push the unit into the cutout from the front, and clamp it securely from the rear using the mounting adapter.
• 11-Pin Base Wiring Mount an 11-pin circular DIN-rail socket (e.g., P2CF-11) inside the enclosure. Secure all wire connections using screw terminals, ensuring correct polarity for input sensors and output loads.
• Sensor Cable Shielding Route input pulse cables separately from heavy AC power lines and inverter motor outputs. Connect cable shields to a single-point panel earth to eliminate electromagnetic noise interference.

Frequently Asked Questions

• What supply voltage range does the H7CX-A114S-N counter support?

  The unit operates on 100 to 240 VAC supply power at 50/60 Hz, with an allowable operating range between 85% and 110% of rated voltage.

• What type of output circuit is integrated into this model?

  This model features an NPN open-collector transistor output rated for up to 30 VDC and a maximum switching current of 100 mA.

• How is the rear panel electrical interface physically configured?

  The unit connects externally via an 11-pin circular socket interface, matching standard DIN-rail octal/undecal sockets.

• Can the input stage accept both NPN and PNP sensor signals?

  Yes, the input circuit supports both NPN open-collector and PNP sensor signals, configurable via internal settings.

• What display range is supported by the front panel LCD?

  The unit features a 4-digit backlit display providing a full numeric count and tachometer range from 0 to 9999.

• How are configuration parameters stored during an AC power loss?

  All setpoints, totalized counts, and operating parameters are saved to internal non-volatile EEPROM memory without requiring a battery.

• What is the recommended panel cutout size for flush mounting?

  The unit requires a standard 45 x 45 mm square panel cutout for flush mounting in control cabinet doors.

• What is the operating temperature rating for field cabinet installation?

  The instrument is specified to operate reliably in ambient panel temperatures ranging from -10 to 55 deg C.
