S-5844A77DC-I4T1U3

The S-5844A77DC-I4T1U3 is a solid state thermal controller made by Johnson Controls. It is used in many industrial, commercial and residential applications. It features a fail-safe design and can be used to control temperatures ranging from -20°F to 850°F. The device is small enough to fit into tight spaces, yet is rugged enough to withstand extreme temperatures, shock and vibration.The S-5844A77DC-I4T1U3 is based on a solid state technology and has a very low power consumption. This type of controller provides reliable and accurate temperature control. The device is equipped with an adjustable control switch that allows it to be set to turn off electrical appliances at a specified temperature.The S-5844A77DC-I4T1U3 can be used in processes such as air conditioning, refrigeration, heating, cooling, and industrial process control. It can also be used to detect temperature differences in confined spaces, such as between two different parts of a machine.The S-5844A77DC-I4T1U3 is designed to be used with Johnson Controls\' RTJ425 High Temperature Snap Disc Control. The controller is mounted in a thermally insulating housing. The electronic temperature sensing element, which is mounted inside the housing, contains a precision backed-out thermistor. This thermistor is highly sensitive to any changes in temperature, and its resistance changes proportionally to the temperature.When the temperature reaches a threshold (set using the adjustable switch), the thermistor sends a signal to the snap disc control. The snap disc control then triggers a signal that can be used to operate a device, such as a fan, valve, or relay. This process is known as temperature control, which is the primary function of the S-5844A77DC-I4T1U3.The S-5844A77DC-I4T1U3 also features an adjustable low-temperature offset. This feature allows the user to set the temperature below which the device will not activate. This is particularly useful in applications such as air conditioning, where it is often desirable to not activate the device until the temperatures start to increase.In addition to its temperature control features, the S-5844A77DC-I4T1U3 also has multiple alarm points, and adjustable hysteresis. These features allow the device to be used in more sophisticated applications, where multiple temperature thresholds must be monitored and multiple outputs triggered.The S-5844A77DC-I4T1U3 is an extremely versatile and reliable device that is suitable for a wide range of industrial applications. Its wide temperature range, adjustable control switch, and multiple alarm points make it an excellent choice for temperature sensing and control. Its small size and low power consumption make it a great choice for tight spaces, and its rugged construction ensures reliable operation in even the harshest of environments.
