Configured for high-speed pulse accumulation and discrete setpoint switching in process automation systems, the Omron H7CC-A8D (H7CC-A Digital Counter) provides direct physical/electrical execution.

Nomenclature & Code Architecture

• H7CC: Standard 48 mm x 48 mm digital counter series baseline design.
• A: Standard functions (1-stage preset counter / total and preset counter configuration).
• 8: Round 8-pin socket interface structure.
• D: Operating power supply rating covering 24 VAC (50/60 Hz) and 12 to 48 VDC.

Core Electrical & Operating Characteristics

Signal Integration & Network Expansion

The processing unit preserves deterministic backplane bus communication velocity across adjacent PLC modules and remote racks, supporting expanded I/O density scaling. Operating routines maintain ongoing firmware flash compatibility across Sysmac setup utilities to prevent parameter drift during high-frequency input cycles.

Standard Package Items

• 1 x Omron H7CC-A8D Digital Counter Unit
• 1 x Panel Mounting Adapter & Rear Flush Sleeve

Mechanical Mounting & Wiring Steps

Panel Cutout & Installation

Insert the unit through a standard 45 mm x 45 mm DIN panel cutout. Push the mounting adapter from the rear until the front bezel gasket seals flush against the panel surface.

Base Socket Termination

Align keyways and insert the unit into a compatible 8-pin socket (such as P2CF-08 or P3G-08). Tighten screw terminals firmly to secure wiring leads.

Shielding & Input Wiring

Route high-speed count sensor wires through grounded shielded pair cables. Keep input leads isolated from power line conductors to prevent electromagnetic counting errors.

Frequently Asked Questions

• What supply voltage options does the H7CC-A8D accept?

  The unit operates on 24 VAC (50/60 Hz) or a DC voltage range of 12 to 48 VDC across its rear power terminals.

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

  The unit features a 6-digit transmissive LCD screen displaying actual count values and 1-stage setpoint levels.

• What interface style is used for back connections?

  Connections are made via a standard round 8-pin socket arrangement compatible with rear-mounting track sockets.

• What control output switching capability is embedded on the unit?

  The counter contains a Single Pole Single Throw Normally Open (SPST-NO) relay contact output rated for discrete load switching.

• Can the unit be configured as both a totalizing and preset counter?

  Yes, internal configuration allows setup as either a standard 1-stage preset counter or a totalizing preset counter.

• What is the physical weight of the standalone counter body?

  The unit weighs approximately 120 g, reducing strain on thin enclosure panel cutouts.

• Does changing system firmware alter saved preset counter values?

  No, operational configurations and preset parameters reside in non-volatile memory unaffected by external processor firmware updates.

• What insulation steps prevent inductive noise from causing miscounts?

  Input signal cables must use shielded twisted-pair cabling separated from AC power lines by dedicated wiring conduits.
