The K8AKPH1 200/480VAC is a part of the Omron K8AK series of transition relay modules. The K8AK series is used for a wide range of control applications, including transition starting, speed control, and frequency control. The K8AKPH1 200/480VAC provides two relay outputs that can be used to transition from one voltage level to another, such as from 200V to 480V. This transition relay module is designed to provide an efficient, low-voltage-drop transition, protecting the system from power surges and abrupt voltage drops. The K8AKPH1 200/480VAC is designed with a wide operating temperature range of -25° to +60°C and can operate in humidity ratings of up to 100%. It has a contact arrangement of 1 x NO and 1 x NC, and can be used with a variety of other Omron products, such as safety relays and process controllers.
