§Small-sized plug-in transducer§
2-output type

Potentiometer transducer
FWRT■ Application
Replaces mechanical displacement of an angle or a position withresistance value change of a potentiometer, inputs the resistancechange, then insulates and. converts it into a DC signal
proportional to the change. Because this transducer can extract
two insulated outputs, control and monitor can be done by a single
unit. Up to 16 units can be housed in an installation base.

Compact and high withstand voltage.
Withstand voltage between input/output/auxiliary
supply/outer case is AC2, 000V (50/60Hz) for 1 min..
Withstand voltage between outputs is AC500V (50/60Hz)
for 1 min..
Compatible with resistance range 100Ω-10kΩ of apotentiometer.
Constant voltage/current output type. No need to adjust theproduct if it operates within load resistance range.
A LED can confirm status of electric power applied.

29.5×76×125mm/180g■ How to adjust(1) Please adjust 1st output ZERO VR/SPAN VR of front VR in accordance with thepotentiometer you actually use. Hereat 1st and 2nd output are changing simultaneously.
Variable range of 1st output ZERO VR/SPAN VR are as follows.
(ZERO VR: 0-50% of nominal resistance value, SPAN VR: 50-100% of nominal resistance value)(2) 2nd output ZERO VR/SPAN VR of front are sensitivity difference (between 1st and 2ndoutput) adjusting VR. Ordinarily, there is no need to adjust it. Only use it when an adjustment
is required Variable range of 2nd output ZERO VR/SPAN VR is adjustable within ±2%.
