The N3000 Big Digit controller is a 1/4 DIN Universal temperature and  process controller which accepts signals from most types  of sensor.  The N3000 contains in one single instrument all of the major features required in the vast majority of industrial processes. From the very simple applications such 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.

Universal Sensor Input
The N3000 accepts a wide variety of sensor types.  These sensors include thermocouples type J, K, T, N, R, S; PT100 RTD, linear 4-20mA,
0-50 mV, 0-5 Vdc, 0-10 Vdc.

Multiple Outputs as a Standard Feature
The N3000 has multiple standard output capabilities.  These include:

  • Four relay outputs
  • One multi-function output which can be configured as an analog output(0/4-20mA)  used as a control output or retransmission of the process variable or set point.  The same output can alternatively configured as a pulse output.
  • One multi-function I/O which can be set as a pulse output or digital input

Remote Setpoint
The controllers setpoint can be set  by an external 4-20mA analog input signal.

ON/OFF and PID and Control with  Autotune
The N3000 supports on/off and PID control modes of operation.  When in the PID mode the controller can be manually tuned or set for autotune. The controller may be used for heating or cooling applications.

Ramp and Soak Profiles
The ramp and soak feature allows the controller to change its setpoint over time according to a user defined time/temperature profile. Each profile can contain up to seven segments(setpoints) and seven different profiles may be stored in the controller.  One profile can be linked to another allowing for a profile with up to 49 segments.

Example of an Ramp and Soak Profile

Four Modes of Independent Alarms
Any of the relay outputs may be configured as an alarm.

  • Sensor Break Alarm - Activated whenever the input sensor is broken or disconnected.
  • Ramp & Soak Program Event Alarm - Activated when a specified segment in the Ramp & Soak program is reached.
  • High or Low Alarms - Triggered when a value goes above or below a set alarm value.
  • Differential Alarm - Triggered when the process value differs from the setpont by a specified amount.

Alarm Timer Functions
The controller alarms can be configured to perform four timer modes:

  • Normal -  Alarm applied without any time element.
  • Delayed - A time delay is applied after the occupancy of an alarm event.
  • Pulse -  After an alarm event the output is pulsed for one time period according to a set time value.
  • Oscillator - After an alarm event the output is pulsed on and off with on/off according to set duration periods.

Digital Input
The N3000 has a digital input which can be provide five different functions

  • Switch the controller from automatic to manual mode.
  • Start or stop the control action
  • Change the controller from following the programmed setpoint to the remote setpoint input.
  • Enable or pause the execution of the Ramp and Soak program.

Auxiliary 24V Power Supply
The controller provides a voltage power supply of 24Vdc used for  excitation of  field transmitters with 25mA current capacity.

USB Communications Standard and Optional RS485 with Modbus Protocol
The N3000 comes standard with USB communications.  The USB communications is primarily used for configuring the controller.  All configuration settings can be accessed through the front key panel but USB port provides configuration via software commands.  The N3000 is also available with optional RS485 communications.  Both the USB and RS485 communications use Modbus protocol.

Free Configuration Software - QuickTune

QuickTune Software

QuickTune is a free software tool for parameter configuration of NOVUS controllers and indicators. With its clean interface any lay or advanced user can friendly access and modify all device functions for proper configuration. Designed for easy and quick commissioning, it provides diagnosis and monitoring resources to field technicians.


SuperView - Optional SCADA Software


SuperView is a Supervisory Control and Data Acquisition software (SCADA) that uses visual development interface to create applications. SuperView can communicate with Modbus RTU and Modbus TCP devices. SuperView can also be used in Client or Server modes allowing distributed supervision of a process or system. Different types of resources simplify the configuration, bringing flexibility and ease when developing an application.
