N1200

Description

N1200 is an advanced self-adaptive PID controller with an algorithm that constantly monitors the process performance and adjusts PID settings in order to obtain the best possible control response in all situations.
The N1200 is able to accept most industrial sensors and signals and provides a large array of output types common to process control.
Configuration of the N1200 is done using the front panel buttons, without performing any hardware change.
The multi-purpose inputs and outputs can be combined to provide tremendous versatility with extremely high accuracy in the most demanding applications.
The N1200 is available in several models with 3 relays and RS485 connectivity as an extra, this allows the device to be more adaptable to various applications and also enables the integration of the N1200 signals into a supervisory system such as SCADA adding to the tremedous adaptability of the device.
