How many amps does the 12v coil draw when energized?

Description says the coil is 120v not 12v

Please send wiring diagram. Does the output side of the coil switch only 1 hot leg of 220V?

Each relay is single pole double throw (SPDT), so it can switch only one circuit. It could select between hot legs of 220 VAC, but to control both legs simultaneously, a double pole double throw (DPDT) relay would be better. Two SPDT relays could do the job, but might not stay perfectly in sync. These SPDT relays have 5 contacts. Two control the coil. The other three control the secondary circuit. Common is connected to Normally Closed when the relay is deenergized and to Normally Open when the relay is energized. Mine came with two thinner wires for the coil and three thicker wires for the load contacts. They've worked great in my application, powering a load when both inputs are energized in one case (pump that recirculates hot water based on temperature and human occupancy) and when either input is energized in the other case (freezer with time-of-day and temperature inputs).

Can i hook up the relais like this..............on the nc a humidifier and on the no a dehumidifier ? the relais will be controled by a photocell.

I would need more info for sure, but it would work if the photcell has a 12VDC circuit. What the power draw on the humidifier, it would need to be under 15A AC. AC only on the load side.

Are these ul approved? local building codes require ul approved devices.

What is a CE mark and is it equivalent to a UL Listing Mark? A CE Marking is a European marking of conformity that indicates that a product complies with the requirements of the applicable European laws or directives. The European Community established the CE marking system to ensure free movement of products between member countries and to remove internal barriers to trade. The CE marking is a legally required marking in the European Union (EU) and applies to a variety of product categories. It is usually a manufacturer’s self-declaration that the product complies with European laws and may not include assessment to safety requirements. Because most products bearing the CE mark are not required to be third-party certified, are not subject to ongoing factory surveillance of production, and may not be compliant with applicable U.S. product safety standards, they are not considered to be Listed as defined in NFPA and ICC model codes and standards.
