Omron LY1 Series Power Relay, 24V Coil Voltage, 15A Switching Current - LY1-0 24VDC


This power relay is a Compact electromechanical switching device designed for control and switching tasks within industrial automation and electronic systems. It operates from a 24V DC drive and provides a single changeover contact to manage AC or DC loads. The relay is built for PCB mounting with solder-style terminals and is suited to environments requiring standardised approvals.

Features and Benefits:


• 900mW Coil reduces energy consumption in control circuits
• 650Ω Coil resistance delivers predictable Coil current draw
• SPDT contact arrangement enables single-pole changeover control
• Silver-alloy contacts ensure consistent low-contact resistance
• Switches up to 15A at 250V AC for moderate power loads
• Rated switching at 125V DC for DC load applications

Applications


• Suitable for motor starter control in industrial panels
• Ideal for signal switching in automation controllers
• Used with control PCBs in HVAC systems
• Can be used for switching DC loads in battery systems
• Used for relay logic and interlocking in machinery control

What Terminal type should installers expect for PCB integration?


The unit uses solder-style terminals arranged for PCB mounting to allow direct board soldering.

What environmental temperature range can it operate within?


It functions across an ambient range from -25°C up to a maximum of 55°C, permitting use in many indoor industrial settings.

How does the contact resistance affect switching performance?


Contact resistance is specified at 50mΩ, which minimises voltage drop across the contact under load and supports efficient power transfer.

Are there recognised safety approvals associated with this device?


It holds approvals from UL and CSA, indicating compliance with those standard testing regimes.

What physical footprint considerations should be noted for panel design?


The relay presents a Compact profile with a height of 28mm, a width of 36mm and a length of 21.5mm, enabling tight placement on populated boards.
