The SV9Z-J20S is a jumper accessory designed for IDEC RV series relays, providing a 20-point contact configuration in blue. It features gold-plated contacts for reliable electrical connection and is pre-assembled with a DIN mount socket for easy installation. The jumper accommodates a wide input voltage range of 6 to 240V AC/DC with built-in surge suppression and includes a green LED indicator. It has a space-saving 6 mm width and 70 mm height from the DIN rail, with universal screw terminals (flat and Phillips head) and spring clamp terminals accepting 20–14 AWG solid or stranded wires. The device is rated for 400V AC maximum switching voltage and 1500 VA maximum switching power, with high dielectric strength and impulse withstand voltages, reverse polarity protection, and a lever for easy relay locking and removal. This jumper is ideal for industrial automation and control applications requiring compact, reliable relay socket solutions with universal AC/DC compatibility.
