Omron LY4 Series Power Relay, 48V Coil Voltage, 10A Switching Current - LY4 48VDC


This power relay is a PCB-mount switching device designed for control and signal applications in industrial environments. It operates from a 48V DC Coil to change multiple circuits simultaneously and is intended for installation where Compact plug-in relays are required. The unit is suited to control panels and automated systems that need reliable mechanical switching of AC loads.

Features and Benefits:


• Four-pole changeover contacts allow independent circuit control
• Coil consumption 0.9 W reduces drive power requirements
• Contact resistance 30 mΩ ensures low-voltage drop under load
• Switching capacity 1.1 kVA supports high-power AC circuits
• Rated switching 250V and 10A for mains-level switching
• Plug-in terminals simplify removal and replacement

Applications


• Suitable for industrial control panel contact switching
• Ideal for motor starter interlocks in automation systems
• Used with PLC outputs requiring multiple changeover contacts
• Can be used for power distribution switching in small switchgear
• Suitable for retrofit replacements in legacy relay boards

What mounting method does it use for board assembly?


It is supplied in a PCB-mount format with plug-in terminals for insertion into corresponding sockets to ease installation and servicing.

What environmental operating range must be observed?


The relay operates between -25 °C and 40 °C, so ambient conditions should remain within these limits for reliable operation.

How does Coil resistance affect drive circuitry?


The Coil has 1 600 Ω resistance, which determines the current draw at 48V DC and should be considered when designing the driver stage.

What physical form factor impacts panel layout?


The relay has a Compact profile with a height of 42.4mm, length of 28mm and width of 41.5mm, which assists in dense PCB layouts.
