The temperature acquisition signal is a weak signal of millivolt level, it is recommended to connect directly to the terminal of the module
Two-wire wiring (independent temperature input)
Two-wire wiring method (analog and temperature mixed type)
Three-wire (PT100/PT1000) wiring
In some specific occasions, it is necessary to transfer the wiring through the terminal block, and special attention must be paid not to directly connect the power supply 0V and the signal reference point, and must be connected separately with independent terminals.
