N3000-485 PID Process Controller with RS-485 and USB, 240 V

N3000-485 PID Process Controller with RS-485 and USB, 240 V

The N3000 Big Digit Universal Process Controller is a real breakthrough in versatility for holding in one single instrument all the major features required in the vast majority of industrial processes.

With a sophisticated and consistent software and its advanced truly universal circuitry, the N3000 accepts configuration of both input signal and control output through the front keyboard without any internal hardware change.

Power supply for remote loop powered transmitters is standard and is a must for high-end applications.

From the very simple applications as a temperature controller to the most complex systems of distributed control with PLCs or SCADA networks, the N3000 is the right answer to your needs for industrial or laboratory automation.

Configuration can be performed directly on the controller or through the USB interface. The free NConfig software for Windows is the configuration management tool. When connected by USB, the controller appears as a serial port on the host computer.

NConfig can be used to batch program these controllers via USB, even when the controller is unpowered.

The controller acts as a Modbus RTU slave on the USB and RS-485 ports. You can use our ViewPID software to help you monitor, tune and record the performance of the controller with graphs of performance. Additionally, Novus Superview or our ISEE-Modbus can be used in production to log data and performa actions on alarms.
