    AI Overview
    The ABB 1SVR730850R0200 is the CM-ENS.21S liquid level monitoring relay,
    a device for controlling the level of conductive liquids. It uses three electrodes to measure the liquid's resistance and can be configured for either filling or draining applications. The relay has a wide supply voltage range (
    24−24024 minus 240
    24−240
     V AC/DC) and features a single SPDT (Single Pole Double Throw) output contact for pump protection or overflow prevention. 
    Key features 
    • Application: Regulates and controls the level of conductive liquids for filling, draining, overflow, and dry-running protection.
    • Measurement: Monitors the electrical resistance of the liquid between three electrodes to determine the liquid level.
    • Functionality: Can be set via a front potentiometer to operate in either a "fill" or "drain" mode.
    • Power Supply: Operates on a wide control supply voltage of
      24−24024 minus 240
      24−240
       V AC/DC.
    • Output: Provides a single SPDT (1 c/o) contact, rated for up to
      250250
      250
       V and
      44

       A.
    • Sensitivity: The sensitivity is adjustable from
      0.10.1
      0.1
       to
      10001000

      .
    • Durability: Offers a mechanical lifespan of up to 10 million switching cycles.
    • Indicators: Includes a steady green LED for power and a yellow LED for electrode/alarm status.
