Output Ratings

Analog Voltage Output: 0 to 10V dc

Minimum load resistance = 500 Ω

Minimum required supply voltage for full 0-10V output span = (

1000

+ 13)V dc

RLOAD

Analog Current Output: 4 to 20 mA

Maximum load resistance = 1 kΩ or (

V supply - 5

) Ω, whichever is lower

0.02

Minimum required supply voltage for full 4-20 mA output span = 10V dc or

[(RLoad x 0.02)+5]V dc, whichever is greater. 4-20 mA output calibrated at 25° C with 250 Ω load.

Discrete Output: 150 mA max.

OFF-State leakage current: less than 5 µA

Output saturation: NPN: less than 200 mV @ 10 mA; less than 650 mV @ 150 mA

PNP: less than 1.2V @ 10 mA; less than 1.65V @ 150 mA

Temperature Effect

Connection options: A model with a QD requires a mating cordset (see page 312).

For 9 m cable, add suffix W/30 to the 2 m model number (example, QT50ULB W/30).

* For sensors with Teflon

-protected face and transducer, add suffix -CRFV to the model number (example, QT50ULB-CRFV).
