LLC54AA

LLC54AA is anLLC5 series protection relay for drain (pump-down) operation with adjustable sense resistance. It provides dual-probe conductive liquid level control in a convenient octal plug-in package. Less than 1mA of current is used to sense the presence of conductive liquid between the probes and the common. When the liquid level rises and touches the high-level probe, the output relay and LED energize and remain energized until the liquid level falls below the low-level probe. The output relay and LED de-energize and remain de-energized until the liquid rises and touches the high-level probe.

• Unique probe protection logic-probes are protected from scale buildup
• LED status indicator-visual indication of relay engagement in pump-up or pump-down activity
• Isolated 5A SPDT contacts-allows control of loads for AC voltage
• 120V AC line voltage
• Response time: debounce time delay <1s
• Isolation voltage: ≥ 1500V RMS between input, output, and probe
• Plug-in socket mounting
• Octal 8-pin plug-intermination
• Dimension: 2.39" H x 1.78" W x 3.01" D
• Operating temperature range from -20 to 60ºC
