Isolated Module TRPxxxxxP series FEATURES RTD detection type isolated module RoHS Two-wire, three-wire or four- wire Pt100 RTD signal input High accuracy of 0.2% FS High linearity of 0.2% FS Isolation test voltage 2.0kVAC for 60s Low ripple & noise: 30mVp-p Extremely low temperature coefficient of 50PPM/ typical, over entire range from -40 to +85 Operating temperature range: -40 to +85 High reliability, Low cost compact design, Convenient to use Standard DIP24 Package (31.6 x 20.3 x 10.2mm), UL94-V0 EN62368 (EN60950) approval TRP series is a hybrid integrated temperature signal isolation module. It converts the RTD (resistance temperature detector) temperature sensor signal into an isolated standard linear current or voltage signal that is proportional to the temperature. The circuit on the same chip integrates a set of multi-channel high isolated DC/DC power supply, several high-performance signal isolators, and RTD linearization, long-term compensation, interference suppression circuit. Especially suitable for Pt100 RTD signal isolation converted into a standard signal isolation, temperature signals transmission and remote without distortion, temperature signal acquisition and isolated of DCS system or industrial site PLC. Chip integrates a high-efficiency DC-DC, it can produce two groups were separated from each other to the internal power amplifier inputs, modulation circuit supply and outputs of the demodulator circuit, switching circuit, and filter circuit. The SMD structure with new isolation technologies allow the device to reach high power to signal input and to signal output Three-terminal isolation of 2000VAC. The products are ideal for use in harsh operating environments where compliance to vibration, industrial grade temperature range and high humidity are required. TRP series temperature signal isolation modules are very convenient to use, to achieve Pt100 RTD signal isolation transmitter with a minimum of external components.
