Ametek National Controls Corp. (NCC) Dust Collector; 120, 220 VAC; 2 VA (Max.); 50/60 Hz; -40 to degC BOX-A1008-CHNF

2 VA (Max.) Power Consumption, -40 °C to +66 °C Operating Temperature, Dust Collectors AMETEK NCC Dust Collector Controls offer sequential control of solenoid valves for pulse or shaker-damper cleaning of dust collectors. They are also used for display lighting, intermittent valve or sequential control. The control has two operating modes: Continuous Mode: The pressure switch terminals are shorted. Upon application of input voltage, the control activates output #1 after the preset off time. It will continue to activate outputs sequentially until input voltage is removed On Demand Mode: The pressure switch terminals are connected to an isolated set of contacts of a differential pressure switch. The control will activate the outputs sequentially whenever the pressure switch contacts are closed. When the pressure switch contacts open, the output sequencing stops. Re-closing of the contacts will cause the control to resume activating the outputs. 120 or 220 VAC voltage rating. 50⁄60 Hz frequency.
