The ABB RB121A Compact High-Performance Relay 24V, 1SNA645005R0700, is engineered for both AC and DC applications, offering versatility and efficiency. Its compact design, measuring 2.7 inches in height, 2.55 inches in width, and 0.25 inches in depth, makes it ideal for space-constrained installations. Weighing just 0.72 ounces, it ensures minimal load and easy handling. The relay features a 1 c/o (SPDT) output with gold-plated contacts rated at 250 V / 6 A, providing reliable performance for industrial and automation tasks. The RB121G-24VUC model includes a boxed interface with screw terminals, allowing seamless snap-on mounting onto a DIN Rail. The soldered relay within the device housing offers high resistance to vibration, enhancing durability. Operating with a 24 V AC/DC rated control supply voltage, it is suitable for electrical isolation, amplification, and signal matching, enabling the switching of high currents on a small footprint. An integrated LED provides visual indication of the relay coil's energization, while the UL 94-V0 certified device housing ensures high levels of flame retardation for improved safety. Accessories such as jumper bars are available to enhance functionality.
