Schneider Electric RM35UA11MW Harmony Voltage Control Relay 5A 2CO 0.05-5V AC/DC 24-240V Control Relay

The Schneider Electric RM35UA11MW is a Harmony RM35-U multifunction voltage control relay, measuring a 0.05-5 V AC/DC signal for overvoltage or undervoltage conditions while powered from a 24-240 V AC/DC supply. It switches two 5 A changeover contacts with an adjustable 0.3-30 second fault delay, in a 35 mm wide DIN rail housing.

Selection Notes

RM35UA11MW's 0.05-5 V measurement range is sized for low-level signals straight off a current-transformer burden resistor or a voltage-divider tap, well below mains level. Where the signal to monitor is a 1-100 V sensor or transformer secondary instead, the RM35UA12MW sibling covers that band on the same 24-240 V AC/DC supply and 2 C/O 5 A output, and the RM35UA13MW extends to 15-600 V for direct mains-level monitoring - all three share one housing so the choice is purely the input range needed. Reliability data rates the RM35UA family at B10d = 290,000 operations and an MTTFd of 308.2 years, the same figures across the 0.05-5 V, 1-100 V and 15-600 V variants since all three share the same output stage and mechanical contacts.
