Omron H5CX-A11-N H5CX Series Digital Multifunction Timer

Description

Designed for precise temporal control in complex industrial automation architectures, the Omron H5CX-A11-N is an ultra-compact, 11-pin socket-mount digital multifunction timer operating on a wide 100 to 240 VAC supply voltage. This highly reliable control component integrates advanced digital timing functions with a clear, dual-color display interface, enabling seamless setup and immediate operational feedback directly on the plant floor. Engineered for longevity and performance, the H5CX-A11-N supports multiple timing modes and input configurations to easily adapt to standard electrical panels and machinery control circuits.

Key Features

• Dual-Color Display: Highly legible PV (Present Value) display in 12 mm red characters, complemented by a 6 mm green SV (Set Value) display for instantaneous status verification.
• Versatile Operation Modes: Supports key timing configurations including ON-delay, OFF-delay, Repeat Cycle, and Signal ON/OFF-delay to match complex automation logic.
• Flexible Mounting: Equipped with an 11-pin round socket connector, facilitating rapid DIN-rail chassis mounting or flush panel integration.
• Input Compatibility: Accepts both NPN (no-voltage) and PNP (voltage) external inputs for flexible sensor and controller integration.
• Robust Memory Protection: Internal EEPROM backup retains vital user configurations and program parameters during unexpected power losses.

Applications

• Packaging Equipment: Managing seal jaw timing, bag sealing cycles, and sorting conveyor intervals.
• Thermal Process Units: Regulating precise heating, curing, and dwell times in industrial ovens and dryers.
• Fluid & Pump Management: Managing alternate-pump cycling and automated backwash flush intervals in water systems.
• Machine Tool Lubrication: Driving cyclic lubrication solenoids to protect high-speed bearing housings.

Alternative Models & Compatibility

The modern H5CX-A11-N directly succeeds older non-N legacy models (e.g., H5CX-A11). This updated model features enhanced display brightness and updated firmware parameter structures. When migrating to the "N" designated unit, verify parameter configurations through the front-key system as factory default settings may vary slightly from obsolete revisions. Physical form-factor, 11-pin terminal block mapping, and mounting footprints remain strictly backward-compatible.

Application Pitfalls & Engineering Notes

Avoid routing signal inputs (Pins 1, 3, 4, 5) inside the same conduit run as heavy power lines or AC motor leads to prevent electromagnetic interference. Standard high-frequency spikes can bypass the input filter and trigger ghost starts or unexpected resets. If mounting in unventilated electrical panels alongside high-current components (like motor drives or solid-state relays), ensure local ambient temperatures do not continuously exceed the 55 degC operational threshold.

Commissioning & Wiring Tips

Before powering up the system, determine if the external control device operates on open-collector NPN or source PNP logic. The internal input selector must be correctly set via the operational keys to align with this logic. Misaligned configuration may prevent the timer from recognizing signal input pulses. When utilizing the Reset function, ensure a minimum contact pulse width of 1 ms or 20 ms is selected based on key-bounce filtration requirements in the internal parameter menu.
