KTN-R-90 is a richly featured relay manufactured by ABB. It has many applications, ranging from industrial to consumer. It is also widely used in the home automation and security markets for its ability to detect burglary or fire emergencies and operate connected devices autonomously. Its features include an advanced microprocessor, a heat-sensing infrared isolator, an anti-tamper switch, and robust mechanical design.

KTN-R-90’s primary purpose is to detect and respond to various electrical occurrences. It has two main functions: activation and deactivation. The activation function is responsible for sending a signal to activate an electrical device or system. KTN-R-90 uses a combination of electro-mechanical and electronic components to activate and deactivate devices. The deactivation function is responsible for sending a signal to turn off an electrical device or system. Depending on the type of device connected, the signal may be triggered by a manual switch, temperature, voltage or current, or a combination of these.

The KTN-R-90 also has an adjustable timer, allowing it to send automated activations and deactivations according to predefined intervals. This can be used to automate certain tasks, such as providing temperature regulation or to reduce energy usage. The timer can also be used to detect and respond to changes in an environment which triggers an alarm or other action.

The KTN-R-90 is also equipped with an adjustable sensitivity setting. By enabling this setting, it can detect even the slightest changes in current or voltage, such as a spark or static current. This can be used to provide quick and accurate detection of fault currents and provide an early warning system. This feature can also be used to detect tampering and set off an alarm.

KTN-R-90 is a reliable and versatile electronic relay suitable for a broad range of applications. It offers an economical and efficient way to detect and respond to various electrical occurrences, promote energy savings, and ensure safety. With its adjustable timer and adjustable sensitivity settings, it is a great choice for automation, home automation, and security systems.
