Features
• RCC voltage transducer
• Compact panel Mount type
Remarks
• When sensing voltages, the range of
the sensed voltage can be adjusted
by adding an external input resistor
on the input side.
Advantages

• No external power supply is required
• Good overall accuracy
°C ^{• Excellent linearity}
°C ^{• Low temperature drift}
g ^{• Fast response time}
Notes : ¹⁾ R_IN is not needed whenV_P is less than 26.6V.
Power rating of R should be more than 0.02 x V W
