The Omron H5CX-A11-N AC100-240, also cataloged as the H5CX-A11-N Digital Multifunction Timer, operates as a dedicated hardware component for programmable time delay execution and pulse interval switching within industrial sequence control panels.

Part Number Breakdown

• H5CX: Ultra-compact 48 x 48 mm digital timer product family.
• A: Standard functions with basic timing modes (ON-delay, repeat cycle, signal OFF-delay, interval).
• 11: 11-pin round socket connection configuration.
• N: Updated model revision featuring enhanced display color switching and dual-timer functions.
• AC100-240: Rated operational power supply voltage range (100 to 240 VAC, 50/60 Hz).

Technical Specifications Matrix

Industrial Control Integration & Execution

The unit integrates into standard automated panel networks to process precision timing cycles with high-frequency repeat accuracy. Deterministic logic execution ensures zero timing jitter across multi-stage machine operations, while non-volatile memory registers retain firmware flash compatibility and program parameters during power interruptions without requiring battery backup.

Package Contents

• 1 x Omron H5CX-A11-N AC100-240 Digital Multifunction Timer
• 1 x Waterproof packing gasket (for NEMA 4X / IP66 front panel sealing)
• 1 x Panel mounting adapter frame
• 1 x Instruction manual sheet

Physical Mounting & Electrical Wiring Guidelines

• Insert the timer chassis into a standard 45 x 45 mm DIN front panel cutout, securing it with the rear panel adapter.
• Wire the 100-240 VAC supply lines to pins 2 and 10 of the standard 11-pin socket using insulated copper wire.
• Connect input control signals (Start, Reset, Gate) to pins 5, 6, and 7 using NPN or PNP solid-state connections or dry contacts.
• Route output switching contacts (pins 1, 3, 4 for SPDT) through dedicated circuit breakers to protect relay contact points.
• Separate high-voltage AC load wiring from low-voltage DC input signal wiring to eliminate electromagnetic noise coupling.

Technical Support FAQ

• Can the H5CX-A11-N be mounted directly to a DIN rail without a panel cutout?

  Yes, the unit connects to a 35 mm DIN rail by inserting it into a standard 11-pin socket like the P2CF-11 rear-connecting socket.

• How is the display backlight color configured on this timer model?

  Display color can be set in program mode to remain solid red, solid green, or switch dynamically from green to red when time expires.

• What happens to the accumulated time count if main power supply fails?

  An internal EEPROM stores current count status and setup parameters continuously, resuming operation upon power restoration.

• Are the signal input terminals isolated from the main supply voltage?

  Yes, internal galvanic isolation separates the high-voltage AC operating supply from low-voltage input control terminals.

• What is the minimum input signal pulse duration required for reliable triggering?

  The minimum input signal duration for Start, Reset, and Gate terminals is user-selectable between 1 ms and 20 ms.

• Can the timer be configured for dual-timing or twin-timer operating modes?

  Yes, the N-series architecture allows selection of twin-timer mode to independently program ON-time and OFF-time duration cycles.

• How is key protection enabled to prevent unauthorized parameter changes?

  Hold down the MODE key while adjusting DIP switches or setup parameters to engage four distinct key-protect security levels.

• Is hot-swapping supported for replacing the timer unit during operation?

  No, line voltage to the 11-pin base socket must be disconnected before pulling the timer unit out of its socket.
