The AccuStar® IP-66 is designed for rugged industrial and outdoor applications. The die-cast, powder coated aluminium housing is suitable for the most hostile environments. Multiple input / output configurations provide for ease of implementation into your application. When utilising the 0.5 to 4.5VDC output, the AccuStar® IP-66 may be operated on a standard automotive 12VDC electrical supply. The watertight enclosure is suitable for use in tower crane and marine applications, under all weather conditions. The 4 to 20 mA current output signal is ideal for machine control applications requiring long cable runs and provides for excellent noise immunity. An 18 to 30VDC power supply is required for the 4 to 20 mA current signal output. EMI and RFI components have been incorporated in to the circuit design to provide noise immunity under the most severe conditions. The AccuStar® IP-66 may be calibrated for full-scale output for ranges from +/- 3º to +/- 45º.
