! 3. TECHNICAL SPECIFICATIONS 3.1 Electrical Operating Voltage Model Series 2100R and 2200R are available in either 12VDC or 24VDC (negative ground systems only) Operating Voltages (Models 2111R, 2112R, 2113R and 2211R, 2212R, 2213R) Model Minimum Nominal Maximum 12V 9.0 12.0 16.0 24V 18.0 24.0 32.0 (Models 2114R and 2214R) Model Minimum Nominal 12V 8.0 12.0 24V 16.0 24.0 Maximum 18.0 36.0 Accuracy Maximum indicator error is less than ±3.
Operating Current ! Total system current is a function of the voltage, sender type, display mode, and the gage’s factory programming. Typical operating currents (not including the current to drive the sender) vary from 16-55 mA, for 12V models, depending on model number. For 24V models, typical operating currents (not including the current to drive the sender) vary from 18-45 mA, depending on model number.
