"This Harmony RUM universal plug-in relay uses cylindrical pins, has a control coil voltage of 230V AC and has 2 changeover contacts double pole double throw with a rating of 10A." "It provides a complete system solution for the most demanding applications." "It also offers one-step lockable test button and “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."
