ATC Diversified SPM-120-AAA-470 Single Channel Seal Failure Alarm - 120 VAC, 470 Ohms, +/-10% Fixed

The ATC Diversified SPM Series single channel seal failure module is a specialized control for monitoring the shaft seal of a submersible pump motor. A leak is detected by sensing the position of a resistive float switch installed in the seal cavity. When the resistance drops below the sensitivity rating, the output relay energizes and the LED illuminates. When the fault condition clears, the output relay resets automatically.

Features:

• 120 VAC, 50/60 Hz
• 470 Ohms +/-10% Fixed Sensitivity
• Monitors Shaft Seal of Submersible Pump Motor
• Connects to Conductive Probe in Seal Cavity
• LED Indicates Output Relay
