Schneider Electric RM35 Harmony Control Relays
Schneider Electric RM35 Harmony Control Relays monitor electrical and physical values to detect abnormal operating conditions, preventing equipment damage and process interruptions. The RM35 series includes relays for monitoring phase, voltage, current, frequency, speed, liquid level, pump, motor temperature, and elevator machine room temperature. The relay outputs provide fault information and support automatic load shutdown or corrective control in industrial and building automation systems. The lineup offers a wide array of optional functions, such as true RMS measurement, selectable memory, adjustable thresholds and time delays, automatic AC or DC recognition, and separate outputs for individual monitored conditions. Schneider Electric RM35 Harmony Control Relays are designed for mounting on 35mm DIN rails and feature a sealable front cover to prevent unintended setting adjustments.
