RESISTANCE TEMPERATURE TRANSDUCER
RHTP2 -■ Use
By inputting resistance value of a 3-wire thermal resistancebased on the JIS, this device insulates and converts theresistance value into a DC signal proportional totemperature.

■ 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. Impulse withstands voltage 5kV, 1.2/50μs (between electric circuit andearth), and positive/negative polarity 3 times each is guaranteed.
4. With output line surge protection. (2, 000A, 8/20μs, positive/negativepolarity)，can transmit an output directly to a distant place.

§ PLUG-IN TRANSDUCER § 1 OUTPUT TYPE
●Built-in linearizer
Resistance value of a thermal resistance is notproportional to temperature. It is converted into an
output proportional to temperature by a linearizer.
●Built-in burnout
Detects disconnection of a thermal resistance and does
scale-out of output to positive (+) side.
Scale-out to negative side is also manufacturable if
specified.
●Specified current
Specified current is a current flowing into a thermalresistance. Change of resistance value can be measured
by voltage drop caused by the specified current.
Standard specified current is 2mA.

●Compensating wire
A compensating wire compensates for the temperature
difference between thermocouple terminals and transducer
terminals. Because color (material) of compensating wire
varies according to thermocouple type, choose acompensating wire compatible with thermocouple. Match
positive/negative polarities when connecting.
