The King K312 Relay Thermostat Slave is a versatile and powerful component designed for use in HVAC (Heating, Ventilating, and Air Conditioning) systems. This 2-form C European style contactor relay is perfect for applications where a secondary heating element requires remote control via a thermostat.
This relay operates on a voltage range of 120-277V AC and can handle a current of up to 15 Amps. Its thermal protection feature makes it suitable for high power applications, as it ensures that the relay does not overheat during prolonged usage. The K312 Relay is a slave unit, meaning it depends on a primary thermostat for temperature sensing and control.
The terminal arrangement of this device is designed to accommodate both 208 and 240 volts, providing added flexibility regardless of the voltage requirements of your HVAC system. All terminals are clearly labeled, making wiring and installation a straightforward process. A convent floating neutral terminal guarantees reliable operation.
The construction of the King K312 Relay Thermostat Slave is robust, ensuring long-lasting performance in demanding environments. It features a solid-state design, providing discrete, silent operation that is free from mechanical parts and wear. The coil heats up quickly and efficiently, enabling fast response times and reducing power consumption.
As a safety feature, the K312 Relay comes with an auxiliary terminal that, when connected to a resistor, provides continuous power to the thermostat. This ensures the thermostat maintains its calibration and is always ready to control the slave relay when called for.
This device comes with a mounting bracket and various hardware for secure installation. The compact size of the relay allows it to be mounted directly onto a DIN rail or a housing for easy organization within a control panel. The relays come with a 1-year warranty from the manufacturer, providing peace of mind for future investments in your HVAC system.
In summary, the King K312 Relay Thermostat Slave is a high-performing and versatile addition to any HVAC system. Its wide voltage range, current handling capacity, and fast response times make it an excellent choice for efficiently controlling secondary heating elements in various heating and cooling applications.
