61F-GP-NT AC120

The 61F-GP-NT AC120 is an electromechanical controller designed for use in industrial liquid-level applications, such as in the control of tanks or reservoirs. It is a comprehensive device with features like built-in manual/automatic control, two-way relay feedback, selectable high/low/reverse actions, and symmetrical/asymmetrical operations. Additionally, it also has a built-in timer with an adjustable startup delay and sensitivity setting.

This controller is designed with a two-way relay feedback system, meaning it can be used in both manual and automatic control modes. In manual mode, the user can adjust the set point directly, while in the automatic mode, the controller will automatically adjust the set point as determined by the two-way relay system. This two-way relay feedback system allows for precise control of the liquid-level application, as well as the ability to detect sudden changes in the level of liquid being monitored.

The 61F-GP-NT AC120 also features a selectable high/low/reverse action mode, allowing the user to select the action to be taken dependent on the monitored liquid level. In the high action mode, the controller will act when the liquid level exceeds the set point and transition to the low action setting when the liquid level drops below the set point. Conversely, in low action mode, the controller will take action when the liquid level drops below the set point, and transition to the high action setting when the liquid level rises above the set point. The reverse action setting is utilized when a liquid level needs to be maintained at a certain level, and the controller will act to maintain the desired liquid level.

In addition, the 61F-GP-NT AC120 is also capable of symmetrical/asymmetrical operations. The symmetrical operation setting can be used when the user desires an ‘unlimited’ range, as it allows the user to adjust the set point to a specific level without limitation. The asymmetrical operation setting can be used when users seek a ‘limited’ range, as it limits the set point adjustment to within a certain range.

The 61F-GP-NT AC120 also has a built-in timer with adjustable sensitivity and startup delay settings. This timer function allows the controller to delay the start of operation when power is reintroduced following a power outage. Additionally, the sensitivity setting of the timer can be adjusted depending on the desired response speed of the controller.

In conclusion, the 61F-GP-NT AC120 is an ideal controller for use in industrial liquid-level applications. Its two-way relay feedback system allows for precise control, and its selectable high/low/reverse actions provide flexibility with the type of action needed. Additionally, its symmetrical/asymmetrical operation settings and adjustable sensitivity/startup delay timer allow for further customisation depending on the needs of the user.
