Omron Series LY Power Relay, 100V AC Coil Voltage, 15A Switching Current - LY1F AC100/110

This power relay is a plug-in electrical switching device designed for industrial control and automation environments. It controls AC and DC loads through a single-pole double-throw contact arrangement, supporting common factory and process applications where dependable switching of moderate currents and voltages is required. The unit operates within typical ambient temperature limits for equipment rooms and plant installations.

Features and Benefits:

• 15A switching current for handling moderate load demands
• 250V AC switching voltage for mains-level AC control
• 125V DC switching capability for DC load applications
• 100V AC Coil with 3750Ω resistance for predictable Coil drive
• Silver-alloy contacts to reduce contact wear and improve conductivity
• Plug-in terminals and surface mountability for Rapid installation

Applications

• Suitable for motor starter control in industrial automation panels
• Ideal for switching heater circuits in process equipment
• Used with control timers and PLC outputs for signal routing
• Can be used for switching DC actuator supplies in machinery
• Suitable for replacement in control cabinets requiring plug-in relays

What ambient temperatures can it tolerate during operation?

It is rated to operate between -25°C and 55°C, suitable for typical indoor industrial environments.

How does the contact configuration affect wiring options?

The SPDT arrangement provides one common contact with both normally open and normally closed outputs, enabling changeover switching without additional relays.

What approvals support use in regulated installations?

It carries multiple standards approvals including VDE, CE, CSA, EN61810-1, EN61984, IEC (TÜV), LR and UL indicating compliance with recognised safety and performance criteria.

What is the expected contact resistance and its relevance?

Contact resistance is specified at 50mΩ, which helps limit voltage drop and heating across the contacts under load.
