Plug-in relay, Harmony electromechanical relays, 15A, 4CO, with LED, lockable test button, 110V DC
Discontinued by Schneider Electric — we can still source the original RPM42FD (new, used or refurbished, subject to availability). Request a quote below.
This Harmony RPM power plug-in relay has a coil control voltage of 110V DC and has 4 changeover contacts 4PDT (quadruple pole double throw) with a rating of 15A. It has large choice of number of contacts for high rated current use. It also offers LED indicator to alert on the current status of the relay. It helps to reduce the size of enclosures and increase machine reliability, you can mount nearly everywhere. This RPM product is IP40. 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.
