SIGNAL TRANSDUCER

ISOLATOR
WTP2 -■ Use
Amplifies various kinds of DC signals and converts them into a unifiedintersystem signal. With input and output insulated, the product offers
full advantages in transmitting insulated signals between measuringsystems, cutoff of noise, protecting a control circuit from a sneak
current, and transmitting an output directly to a distant place.

■ Features
1. Constant voltage/current output
2. Withstand voltage between input, output, auxiliary supply and outercase (earth) is AC2, 000V (50/60Hz), complete insulation for 1 minute.
3. Withstand voltage between 1st and 2nd output is AC1, 000V.
4. Impulse withstands voltage 5kV, 1.2/50µs (between electric circuit andouter case), and positive/negative polarity 3 times each is guaranteed.

§ PLUG-IN TRANSDUCER § 2-OUTPUT TYPESIGNAL TRANSDUCER● Built-in ripple filter
Even if a ripple of single-phase AC full rectification wave (50/60Hz) degree is included in input wave, it still
converts the wave into a smoothed DC signal. Please consult with us for special wave patterns such as an inverter.
● UR-1 precise resistance unit (selling separately)
Please use a UR-1 combined with an isolator of voltage input. When changing the isolator in a hot line state at thetime of current input, if measures against open are necessary, connect UR-1 to socket and convert it into a voltage
signal before using it. (UR-1, the resistance specified)■ Block diagram①Low-drift amplifying circuit②Pulse width modulation circuit③Pulse width demodulation circuit④Output circuit⑤Insulated power source circuit■ Purchase specifications●Item to specify
