Digital Panel Meter / Indicator - Novus N1540 USB (2 relays+4-20 mA) - UK Stock

The N1540 is a powerful Universal Indicator used for local indication of a process variable, offering retransmission via 4-20mA signal back to a control device such as a PLC. Large digits give clear visibility, and a basic requirement such as displaying temperature, pressure or speed can be set up quickly, with further options to set alarm limits linked to the two output relays. It reads process sensors and signals from a universal input, doubling as display, scaling and retransmission all in one, and includes an auxiliary 24VDC power supply for direct connection of 2-wire 4-20mA sensors/transducers. It can also function as a standalone controller — for example, by using the switching outputs it's possible to set up the indicator as a level controller. All configuration is carried out using free Novus software and the onboard USB port. N1540 universal process indicator works at a fast sampling rate, ensuring high-performance indication and response to fast-varying processes. With 5 digits for high-resolution variables and a 17mm-high display, N1540 provides a clear view, making it easier for operators to read and diagnose from a distance. Both electronic robustness and anti-flame material enclosure comply with the main world-class approvals for industry devices. ✅ 3 Year Manufacturer Warranty — backed by our UK-based technical support Novus N1540-RT Datasheet Download Novus N1540-RT Manual Download Technical Details Input Signal/Sensor Types Display: LED 7-segment, 5-digit, 17 mm high Input Type: Thermocouples J, K, T, N, R, S, B, E, Pt100, 0-20 mA, 4-20 mA, 0-50 mV, 0-5 Vdc, 0-10 Vdc Accuracy: Thermocouples J, K, T: 0.2% of span ±1°C; N, R, S, B: 0.2% of span ±3°C; Pt100, 0-20mA, 4-20mA, 0-5Vdc, 0-10Vdc: 0.2% of span Sampling Rate: Up to 55 per second.
