Product Description
The RS PRO 121-7815 Power Relay is a robust industrial relay engineered with a 12V DC coil, supporting up to 10A switching current across its 3PDT (triple pole double throw) contact configuration. This design allows for flexible switching in automated control environments, providing reliability and efficiency for industrial, HVAC, and machine control applications.
Through its plug-in terminal arrangement, this relay enables quick and secure installation, minimizing downtime during extension or replacement within control panels. The gold-plated silver alloy contacts are optimized for stable conductivity and reduced contact resistance, contributing to longer service life and reliable performance even under frequent switching operations.
The RKL Series integrates useful features like an LED indicator for at-a-glance status monitoring and a lockable test button with inspection window, empowering operators with straightforward diagnostics and maintenance. The contact system is designed for durability, allowing this relay to operate reliably in demanding settings from -25°C up to 55°C.
This compact relay (dimensions: 31.5 mm length, 28 mm width, 36.5 mm height) is ideal for space-constrained control cabinet layouts. It accepts both DIN rail and panel mounting bases (ordered separately), improving adaptability across diverse automation tasks. The maximum switching voltage is 30V AC or 30V DC, paired with a robust coil power handling capability of 300 mW, ensuring compatibility with PLC outputs and electronic controllers.
Typical uses include industrial control circuits, motor and actuator switching, logic isolation, and signal routing in HVAC systems, process machines, and building automation solutions. Compliance with RoHS and CE standards guarantees suitability for global deployment requirements.
With RS PRO's quality assurance, the 121-7815 Power Relay is suited for users seeking reliability and flexibility in medium-load circuit switching applications. For other power relay needs, explore the RS PRO range in Power Relays for further options tailored to industrial engineering requirements.
