RSM-05CU is a pluggable slimline relay module designed for compact DIN rail mounting applications with a slim 6.2mm thickness. The module features a 5VDC coil with SPDT (Single Pole Double Throw) contact configuration, rated for 6A at 250VAC or 30VDC, and includes a built-in LED indicator to show relay energizing state. The relay contacts are made of AgNi material with gold-plated options, offering low contact resistance and high reliability with a maximum switching power of 1500VA/180W and mechanical life of 10 million cycles. The module provides IP20 protection rating with screw terminals featuring finger protection, while the relay itself achieves IP67 sealing, and both components are UL recognized. Pluggable jumpers and wire termination provisions reduce installation time, making it ideal for industrial control, automation, and switching applications requiring reliable, space-efficient relay solutions.
