Discontinued by Schneider Electric — we can still source the original RUMF33FD (new, used or refurbished, subject to availability). Request a quote below.
"This Harmony RUM universal plug-in relay uses flat pins, has a control coil voltage of 110V DC and has 3 changeover contacts triple pole double throw with a rating of 10A." "It provides a complete system solution for the most demanding applications." "It also offers “Power On” LED for readiness." "It helps to reduce the size of enclosures and increase machine reliability, you can mount nearly everywhere." "The product is IP40 and has a transparent cover allowing operator to visually inspect the status of contacts." "Workability for hard-wired logic automated systems to complement the functions of industrial programmable logic controllers (PLCs)." "Status display with LED, clearly signal both in the day and night."
