The RM35 series monitoring relays are part of Schneider Electric's product line. They are designed to monitor electrical parameters such as voltage, current, phase sequence, phase failure, and frequency in industrial and commercial applications. These relays are essential for ensuring the proper functioning and protection of electrical systems by detecting anomalies and triggering alarms or protective actions.
Here are some key features and functionalities of the RM35 series monitoring relays:
- Voltage Monitoring:
- Monitors overvoltage and undervoltage conditions.
- Available for both single-phase and three-phase systems.
- Current Monitoring:
- Monitors overcurrent and undercurrent conditions.
- Useful for protecting motors and other equipment from overloads.
- Phase Monitoring:
- Detects phase sequence and phase failure.
- Ensures correct phase rotation and continuous operation of three-phase systems.
- Frequency Monitoring:
- Monitors deviations in supply frequency.
- Ensures stability in applications where frequency consistency is critical.
- Adjustable Settings:
- Thresholds for voltage, current, and frequency can be set according to specific needs.
- Time delays can be configured to avoid nuisance tripping.
- Output Contacts:
- Equipped with relay outputs for signaling and control purposes.
- Can be used to trigger alarms, shutdowns, or other protective actions.
- Compact Design:
- Suitable for DIN rail mounting, making them easy to integrate into control panels.
- LED Indicators:
- Provides visual indication of relay status and monitored parameters.
- Facilitates troubleshooting and system status assessment.
Example Application
In a typical application, an RM35 monitoring relay might be used in an industrial motor control panel to ensure that the motor operates within its specified voltage and current limits. If the relay detects an overvoltage, undervoltage, or phase failure, it will trigger an alarm and/or shut down the motor to prevent damage.
Selecting the Right RM35 Relay
When selecting an RM35 monitoring relay, consider the following:
- The type of parameter you need to monitor (voltage, current, phase, frequency).
- The specifications of your electrical system (single-phase or three-phase, voltage levels, etc.).
- The desired response time and threshold settings for protective actions.
For specific models and detailed technical specifications, refer to the Schneider Electric catalog or datasheets for the RM35 series.
