SIGNAL TRANSDUCER

DISTRIBUTOR WITH SQUARE ROOT EXTRACTIONWSRDTP2 – C 7■ UseSupplies electrical power to a 2-wire transmitter
receives a DC4-20mA signal from the transmitter andoutputs a DC signal proportional to the square root ofthe signal.
WSRDTP2-C7H51(80×50×133mm/450g)■ Features
1. Equipped with functions both of a distributor and asignal exchanger, the transducer is for a 2-wiretransmitter's use.
2. Short-circuit protection function for transmitter circuit(≦30mA) .
3. Supplies a 2-wire transmitter with a stable powersource.
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.
6. Output under 10% shall be clamped at 0% output by acut circuit.
7. DC1-5V (±0.1%) monitoring of the DC4-20mA signal
from the transmitter can be done by the terminal No. 5and No. 6 of the device.

● Built-in ripple filter
Even if a ripple of single-phase AC full rectification wave (50/60Hz) degree isincluded in input wave, it still converts the wave into a smoothed DC signal.
