Load Cell Amplifier, Indicator & Transmitter IQ300
Model IQ300 is a programmable wall-mount precision digital indicator for load cell and strain gauge applications. The 4-line backlit sunlight readable graphic LCD display is quick and easy to set up with plain language menus and prompts.
With precision front end circuitry for high accuracy and stability, the ratiometric circuitry automatically compensates for temperature drift and excitation voltage variances due to cable loss. The load cell excitation voltage is 5VDC for use with both 4-wire and 6-wire load cells, powering up to 6 x 350Ω or 8 x 1000Ω load cells. Advanced features include auto-zero tracking; user input linearisation; max/min recording; programmable front pushbuttons; 3 programmable digital inputs; security menu lockout; motion indication; advanced digital filtering; automatic offset calibration; plus many more to provide an all-in-one precision load cell indicator. RS232 and RS485 serial communications are standard, including MODBUS™ RTU and MODBUS™ ASCII protocols. A simple ASCII-out protocol is also provided for serial printing and communicating to large displays. Model IQ300 includes 4 electromechanical relays, 16-bit analogue retransmission and a Real Time Clock.
