The NOVUS N1500LC is a digital panel meter designed specifically for weighing systems using load cells. It provides a clear 6-digit LED display for measured values and programming parameters, making it well suited for industrial weighing, monitoring, and panel-mounted measurement applications.
The N1500LC supports a wide range of electrical input signals, including 4-20 mA, 0-20 mA, 0-50 mV, 0-20 mV, and -20 to 20 mV. Its configurable indication range allows the display to be set up for the application, while the built-in 5 Vdc or 10 Vdc auxiliary supply provides excitation power for compatible load cells.
Weighing and Load Cell Functions
The N1500LC includes functions commonly needed in scale and weighing applications, such as Tare, Zero Tare, Automatic Zero, Hold, and Peak Hold. It can also store maximum and minimum measured values, helping operators monitor process limits or capture peak weighing events.
Alarms and Output Options
The standard unit includes two alarm outputs, with optional configurations available for up to four alarm relays. Alarm functions include low alarm, high alarm, open sensor detection, and differential alarm modes. Optional process variable retransmission is available as a 0-20 mA or 4-20 mA analog output for sending the measured value to other control or monitoring equipment.
Communication and Configuration
Optional RS485 Modbus RTU communication allows the N1500LC to be integrated into industrial networks for remote monitoring and data acquisition. Configuration is performed through the front keypad, allowing input type, alarm behavior, display scaling, digital input functions, and other parameters to be programmed without changing the internal circuit.
