Product Description

3051D is a high-precision, high-stability temperature transmitter board. The product uses a 12864 dot matrix LCD display with rich display content and functions. It is suitable for up to ten types of thermocouple and thermal resistor signal transmission. The product uses a 24-bit ?-? analog sampling chip to ensure high measurement accuracy; perfect anti-surge and anti-reverse connection design to avoid misinstallation and misoperation in engineering applications; enhanced software security design, including independent watchdog, low-voltage monitoring reset, multi-task scheduling optimization and other functions. All imported components are used to ensure a long service life and stability.

Wiring method

3051D wiring diagram
The wiring method of thermal resistors and thermocouples is shown in the figure above, where the dotted line needs to be short-circuited when connecting the sensor. Please connect the thermocouple in the order of ③ positive ② negative.
Two-wire 4..20mA output, that is, 24V power supply, is connected to the 24V+ and 24V- terminals.
