Operational & Physical Specifications

Deterministic Input Processing & Bus Architecture Interfacing

The internal processing logic continuously measures input frequency and pulse counts at microsecond acquisition rates. Non-volatile EEPROM registers ensure firmware flash compatibility and retain operational parameters during complete supply power outages. Solid-state outputs deliver fast response execution, interfacing cleanly with programmable controllers connected across Profinet / EtherNet/IP deterministic networks via external fieldbus adapters.

Packaging & Included Accessories

• 1 x Omron H7CX-A11S-N Digital Counter/Tachometer

• 1 x Panel Mount Adapter Clip

• 1 x Waterproof Rubber Packing Seal

• 1 x Instruction Sheet

Cabinet Installation & Terminal Wiring Rules

• Panel Cutout Mounting

  Punch a standard 45 x 45 mm DIN opening in the panel door. Fit the rubber seal over the front frame, slide the housing into the cutout, and push the rear adapter bracket until it locks firmly.

• 11-Pin Socket Wiring

  Terminate field connections to an 11-pin circular base socket (e.g., P2CF-11). Observe terminal polarity for line power connections (100-240 VAC) and solid-state transistor output leads.

• Signal Line Shielding

  Run pulse input cables in dedicated metal conduits separated from 3-phase AC power lines and inverter drives. Earth the cable shield at a single cabinet ground point to eliminate noise.

Frequently Asked Questions

• What supply voltage range powers the H7CX-A11S-N unit?

  The unit operates on 100 to 240 VAC at 50/60 Hz, accommodating fluctuations between 85% and 110% of nominal voltage.

• What control output switching mechanism does this model provide?

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

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

  The unit features a 6-digit backlit negative transmissive LCD supporting a full counting range from 0 to 999999.

• How are setup parameters and count values stored during AC line power failure?

  Settings and current count registers are continuously stored in internal EEPROM memory without requiring battery backup.

• What physical terminal layout is used on the back panel?

  The rear interface connects via an 11-pin circular socket arrangement matching standard panel-mount or DIN-rail bases.

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

  Yes, the input circuit accommodates both NPN open-collector and PNP sensor types via DIP switch or internal setup modes.

• What ambient temperature range is allowable inside the control cabinet?

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

• What panel cutout dimensions are required for mounting?

  The unit requires a standard square panel cutout measuring 45 x 45 mm for flush front-panel installation.
