ATC Diversified SPM-120-ADA Temperature Switch Relay - 120 VAC, DPDT

The ATC Diversified SPM series non-volatile latching temperature switch relay monitors a normally-closed-low temperature switch. It incorporates a bi-stable relay that retains its state during power failures. The reset inputs of multiple units may be connected to a single push button as long as proper polarity is observed when making the connections. Under normal conditions the temperature switch is closed and the relay is de-energized. When the temperature switch opens, the relay energizes and latches on until the temperature switch re-closes and the reset button is pressed. The unit will function properly with zero to 2 kOhms of resistance in series with the temperature switch.

Features:

• 120 VAC, 50/60 Hz
• DPDT (Double Pull Double Throw), 10A Contact Rating
• Monitors Normally-Closed Temperature Switch
• Relay Energizes and Latches when Temperature Switch Opens
