Universal Input N1540 Process Indicator 24 VDC/AC (48x96mm)
Five digit universal process indicator accepts thermocouples, Pt100, 4 to 20 mA, 50 mV and 10 V signals. 24 VDC/AC Powered. Mini USB interface
N1540 process 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. The mini USB interface also provides an invaluable means for continuous monitoring of the measured process variable.
With a very short 34 mm depth enclosure, the N1540 can be easily installed in panels and enclosures where space is at a premium. Its 5-digit display allows the indication of high-resolution variables. It has 17mm high digits providing a clear view of the numbers and making it easier to read and diagnose even when operators are far from the indicator.
Dual alarm relays and a convenient 24 V auxiliary power supply are also available in this competitively priced process meter.
