Q468 Input Signal Isolator

Brand: Eurotherm
Does not ship to United States

The Q468 is a DIN rail mount, AC input signal conditioner with 1,800 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 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 Q468 be configured for the proper input range.

For example, a 5 A current transformer output can use the C006 shunt resistor (0.1 Ohm, 5 W) with the input of the Q468 set for 0 to 500 mVac.

The DC output of the Q468 is proportional to the average of the fully-rectified AC input signal, and is calibrated for sine waves between 40 to 400 Hz.
