N1540 1/8 DIN Programmable Temperature Process Panel Meter with USB Communication Port

Overview

The N1540 1/8 DIN Universal Input process meter accepts 8 thermocouple types, Pt100 RTD, mA, mV and 10Vdc input. Based on an advanced and robust hardware platform, the N1540 was designed with advanced technology for highest performance and reliability in the most demanding applications. Fully programmable via the front keypad or via a USB interface with the optional USB Cable and Software. The unique USB interface makes the programming task a simple one step fool proof operation. It allows, the set up of several instruments with the same programming parameters with extreme ease while saving precious time.

With a very short 34 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.
