LT1300 Wall Mount Load Cell Indicator





The LT1300 wall mount load cell indicator is a precision digital indicator for load cell and strain gauge applications.

The high bright 6-digit 7-segment 20mm LED displays and the sunlight readable graphic LCD display make for easy setup and readability. A simple menu system allows for easy configuration of display and load cell settings. The load cell
calibration can be done directly from the load cell calibration certificate or from using known weights.

A universal mains switch mode power supply (85-264VAC) is provided as standard but an optional low voltage (10-30VDC) isolated power supply or a high voltage (25-70VDC) isolated power supply can be installed.

The LT1300 contains precision front end circuitry for high accuracy and stability. The load cell bridge excitation voltage can be field selectable for 5VDC or 10VDC and provides for a Kelvin sensed feedback to compensate for cable loss. The LT1300 can power up to 6×350Ω load cells at 10V excitation and can interface to both 4­wire and 6­wire load cells. RS232 and RS485 communications is supplied as standard with the MODBUS™ RTU and MODBUS™ ASCII protocol.

A simple ASCII out protocol is also provided for serial printing and communicating to large displays. The LT1300 also has analog out circuitry to generate a precision 0/4-20mA, 0-10V or +-10V analog output signal.
The LT1300 also includes advanced features such as auto-zero tracking, user input linearisation, max/min recording, programmable front push buttons, programmable digital inputs, security menu lockout, zero indication, motion indication, advanced digital filtering, plus many more to provide a all in one precision load cell indicator.
