Universal Indicator, 2 Relays, 96x48mm, Indicators

Our Novus N1540 series of process meters 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 programming simple. It allows, for example, the set up of several instruments with the same programming parameters with extreme ease while saving precious time. The USB interface also provides an invaluable means for continuous monitoring of the measured process variable.

The N1540 series is only 35 mm in depth and can be easily installed in panels and enclosures where space is at a premium. Dual alarm relays and a convenient 24V auxiliary power supply are also available in this competitively priced process meter.

Novus has also introduced retransmission models:

  • 8154000220
  • 8154000230

The N1540 has an analog output which performs the retransmission of the measured process variable (PV) values. The analog retransmission can be scaled, i.e., there are minimum and maximum limits to establish the retransmission range. The analog retransmission output is electrically isolated the other indicator circuits.
