AI 生成的摘要: The system enables synchronous, channel-to-channel isolated analog measurements using four RX23E-A microcontrollers, each sampling thermocouple or voltage inputs with a 24-bit Δ-Σ A/D converter every 1 ms. The RX72M MCU collects data every 10 ms via a 3-wire SPI communication bus, minimizing isolator count compared to conventional SPI. It supports 4 isolated measurement channels with high precision, low power consumption, and withstands 1500 VAC isolation. The system suits analog input modules, temperature controllers, and recorders. Power is supplied by DC/DC converters and LDOs, ensuring isolated and stable operation. The package includes multi-channel measurement and communication boards, detailed hardware configurations, and sample programs for implementation.

AI 生成的摘要: Temperature measurement uses resistance temperature detectors (RTDs) with 3-wire and 4-wire configurations to convert resistance changes into temperature data. The RX23E-A MCU performs high-precision A/D conversion using an analog front-end, programmable gain amplifier, and 24-bit Δ-Σ A/D converter. Measurement systems utilize excitation current sources and reference resistors to accurately determine temperature from RTD outputs. Sample programs run on the RSSKRX23E-A board and interface with PC tools for data display. The document details hardware setups, calibration methods, and measurement results across a temperature range of -40°C to 150°C, achieving effective resolutions up to 21.3 bits.
