POTENTIOMETER
WRTP2 – Z

■ UseThis device replaces the mechanical displacement ofan angle or a position by the resistance value change ofthe potentiometer, then insulates and converts it into a
proportional DC signal.

WRTP2-ZH51(80×50×133mm/500g)■ Connection diagram■ Features
1. Can cope with resistance range 100Ω-10kΩ of thepotentiometer.
2. Constant voltage/current output.
3. Withstand voltage between input, output, auxiliary
supply and outer case is AC2, 000V (50/60Hz), complete
insulation for 1 min..
4. Withstand voltage between 1st output and 2nd output
is AC1, 000V.
5. Impulse withstands voltage 5kV, 1.2/50µs (betweenelectric circuit and outer case) positive/ negative
polarity 3 times each is guaranteed.
