WTT2-92A-33(120×56×130mm/0.7kg)■ SPECIFICATIONSContinued on the next page§ BOX TRANSDUCER §SMALL SIZED AC TRANSDUCER 90 SERIES●Standard of auxiliary supply: AC100/110V+10%-15%/AC200/220V+10%-15%/DC24V±15%/DC48V±15% orDC100/110V (88-143V)●Power and reactive power transducer can measure normally from input voltage 0V because the product has anauxiliary supply. Power transducer can be used with SCR waveform.
●Output polarities of reactive power, phase angle and power factor transducer are LAG (+) and LEAD (-).
●Output of a V-V phase angle transducer shall be scaled out to minus side if input voltage of either BUS side or
START side is 0V. (at the time of auxiliary supply)●Output of a V-I phase angle transducer or a power factor transducer becomes equivalent to power factor 1 at thetime of an input voltage 0V or an input current 0A. (at the time of auxiliary supply)●Output of a frequency transducer becomes as follows at the time of input voltage 0V.
●In the case of voltage output 0-5V: approx. -0.6V, in the case of current output 4-20mA: approx. 2mA (at the time ofauxiliary supply).

§ BOX TRANSDUCER §SMALL SIZED SIGNAL TRANSDUCER TT2-91A■ APPLICATIONThis device amplifies various kinds of DC signals and converts them into
unified intersystem signals. Because input, output, power source andearth are reciprocally insulated by a withstand voltage 2,000V, theproduct offers full advantages in transmitting insulated signals between
power measuring systems, cutoff of noise, protecting control circuit from asneak current, and transmitting an output directly to a distant place.
■ FEATURES●Withstand voltage AC2000V 50/60Hz for 1 min. between input, output,
auxiliary supply and earth.
●Impulse withstand voltage 5kV 1.2/50μs positive/negative polarity 3
times each between electric circuit and earth, auxiliary supply andinput/output.
●Supports both DIN rail and wall mounting.

Isolator TT2-91A(120×40×130mm/0.5kg)■ SPECIFICATION*1 Tolerance becomes ±0.5% in the case of input voltage less than 50mV, input current less than 500μA.
*2 For input 10μA, circuit voltage is 15V or less.
*3 Input voltage ranging from 10mV to 600V, input current ranging from 10μA to 100mA are manufacturable.
*4 Consult with us for voltage output up to 10V, current output up to 20mA.
*5 Rated voltage of auxiliary supply DC20―57V is DC24V or DC48V.
► Open current output: The output terminal can be used with the current output terminal open at all times.
Note that approx. 15V voltage will occur at the output terminal.

■ CONNECTION DIAGRAM

In the case of DC auxiliary
supply, connect the wire with S1
as + and S2 as -.

§ BOX TRANSDUCER §SMALL SIZED SIGNAL TRANSDUCER TT2-91A●Specifying special filter
When a ripple equal to a single-phase AC fullrectification wave (50/60Hz) degree is included ininput wave, it is necessary to specify a special filter
to convert it into a DC output. A 50/60Hz fullrectification wave filter is attached by specification.
Also, consult with us for special waveform such asinverter.
■ PURCHASE SPECIFICATION●Response time
Please specify it if a product of a very fast responsetime (60ms/99%) in control circuit is necessary.

§ BOX TRANSDUCER §SMALL SIZED AC TRANSDUCER CONSTANT VOLTAGE/CURRENT TYPE 90 SERIES■ CONNECTION DIAGRAM (in the case of DC auxiliary supply, connect SI as ＋, S2 as －)■ DIMENSIONS (mm) See the connection diagram above for terminal arrangement* Use DIN 35mm standard
rail in the case of DIN rail
mounting (height 15mm).
