ATRVM250-257热电阻模块

The measuring transducers convert a PT100 / PT1000 signal into a linearized measuring signal 0...10V or 0/4...20mA (linearity error 0.1%).

The sensor is fed by an internal current source. The input of the device is executed in three-wire technique. However, also two-wire and four-wire sensors can be used (cf. Connection diagrams).

The devices have a galvanic separation wide-range power supply, that allows a connection at all usual ac and dc supply voltages (19Vdc...255Vac). They can be snap-on mounted onto support rails TS35.
The ranges 0...100°C, 0...200°C, 0...300°C, 0...400°C, 0...500°C and 0...600°C are standard ranges. Other temperature ranges (-200...+1,000°C) are possible upon customer’s request.
