SunYuan SY Z-W-O is a small-size, low-cost passive two-wire 4-20mA loop power supply or three-wire power supply output RTD, thermocouple signal intelligent transmitter integrated module. It can be RTD, thermocouple sensors collected temperature signals according to the amount of change, converted into a linear proportion of the standard 4-20mA current or 0-10V/0-5V voltage signal output, internal software calibration without external power supply and potentiometer adjustment calibration, mainly used for three-wire, two-wire Pt100 / Pt1000 / Cu50 RTD or K, E, S, B, J, T, R, N thermocouple temperature sensor signal acquisition and transmission of intelligent signal. R, N thermocouple temperature sensor signal intelligent acquisition and transmission.

SY Z-W-O integrated module adopts Sunyuan Technology's unique high-efficiency post-feeding invention and patent technology, which can realize the accurate conversion of RTD and thermocouple temperature signals to 4~20mA/0-10V/0-5V standard signals without external power supply, and match with the analog input ports of all kinds of commonly used instruments and meters (e.g., PLC, DCS system, etc.). The product is designed as a low cost, small volume standard SIP8Pin flame retardant module package, which contains signal conditioning circuit, signal ADC conversion circuit, MCU control circuit, digital signal zero, fullness calibration circuit and RTD linearization, long line compensation, interference suppression circuit. Output circuit supply voltage range (7-35VDC), high conversion accuracy, good linearity, fullness and zero point without user calibration, the internal integration process structure can meet the industrial grade wide temperature, humidity, vibration of the site harsh working environment requirements. Users can use the supporting software or APP to re-configure, change the sensor type and range, and flexibly meet the needs of the field.

SY Z-W-O integrated module has a small size, easy to install and use, can be directly placed in the PCB control board or instrumentation meter head, DIN35 rail, armored transmitter inside, the user only needs to add a small number of devices in the periphery, you can realize Pt100 and other RTD, thermocouple sensors, high-precision acquisition and transmission of temperature signals. Among them, the 4-20mA current output module adopts high-efficiency post-feeding technology, which does not require independent power supply, and the two-wire loop power supply output mode can save two power cables, which greatly simplifies the user's design and reduces the user's wiring costs.
