Description: The RM22 and RM35 relay series are designed for monitoring electrical parameters
in industrial automation systems. They ensure continuous protection of motors,
equipment, and electrical networks.
The range includes:
• Three-phase control relays
• Voltage monitoring relays
• Current monitoring relays
Each model provides configurable thresholds, delays, hysteresis, and diagnostic features.-Features
• Overvoltage and undervoltage protection
• Phase loss, imbalance & rotation monitoring (3-phase models)
• Asymmetry detection
• Adjustable trip and reset delays
• Configurable operating modes:
– <U (undervoltage)
– >U (overvoltage)
– >U> (window mode)
– Memory / No-Memory
• Diagnostic push button
• LED status indicators for:
– Relay output (Yellow – R)
– Fault detection (Yellow – Def)
– Power supply (Green – Un)
