The N1540 is a fast sampling (up to 50 samples per second) process indicator with a wide list of input types - Thermocouples, Pt100 RTDs, Voltage and Current – the N1540 is capable of measuring the majority of the variables and sensors encountered in industrial processes.

The N1540 meter was designed with advanced technology for highest performance and reliability in the most demanding applications. Based on an advanced and robust hardware platform, the N1540 can be fully programmed via its front keypad or via a USB interface. The unique USB interface makes the programming task a simple one step fool proof operation. It allows, for example, the set up of several instruments with the same programming parameters with extreme ease while saving precious time.

This powerful but attractively priced panel meter contains two alarms (six functions), sensor offset, configuration of parameters protected by password, serial communication, indication in degrees Celsius (°C) or Fahrenheit (°F), among others.

With a very short 35 mm (1.34 inches) depth enclosure, the N1540 can be easily installed in panels and enclosures where space is at a premium. Dual alarm relays and a convenient 24 V auxiliary power supply are also available in this competitively priced process meter.

The meter configuration can be performed directly on the meters key panel or through the USB interface. We offer a free downloadable software, NConfig software,  for configuration and monitoring through the USB port of a Windows computer.

USB INTERFACE
The USB interface is used for CONFIGURING or MONITORING the panel meter. We offer NConfig software as a free download that must be used for the configuration. It makes it possible to create, view, save and open configurations from the meter or files in your computer. The software can be used for saving and opening configurations in files and makes it possible to transfer configurations between meters and to make backup copies.

For MONITORING purposes you can use any supervisory software (SCADA) or laboratory software that supports the MODBUS RTU communication on a serial communications port. When connected to the USB of a computer, the indicator is recognized as a conventional serial port (COM x).
