The DRI-AC is a DIN rail mount, AC input signal conditioner with 1800 Vdc isolation between input, output and power. The field configurable input and output offers flexible, wide ranging capability for scaling, converting or buffering AC inputs ranging from 5 mA to 100 mA AC or 50 mV to 300 Vac.
For current inputs above 100 mA, it is recommended that an input shunt resistor be used and the DRI-AC be configured for the proper input range. For example, a 5A current transformer output can use a 0.1 Ohm, 5 W shunt resistor with the input of the DRI-AC set for 0 to 500 mV AC.
The DC output of the DRI-AC is proportional to the average of the fully-rectified AC input signal, and is calibrated for sine waves between 40 to 400 Hz.
To set the input level within the dip switch configured range, simply apply the high input signal (voltage or current) and push the CAL button. The low input signal is then applied and pushing the CAL button again stores the low input signal. The high and low input levels are stored in non-volatile memory and correspond to the high and low output levels. These output levels are precisely adjusted using the input signal.
