Multifunctional measure and control module based on field bus

The utility model discloses a multifunctional measure and control module based on field bus. The multifunctional measure and control module comprise a multi-path selection module, a signal conditioning module, an isolation amplification module, an A/D conversion and control module, wherein the above mentioned are connected in order. Signals are collected and put into multi-path selection module, and subsequently given conditioning conversion through signal conditioning module. After that, signals are isolated and amplified by the isolation amplification module and finally they enter the A/D conversion and control module and subsequently signals are converted into digital signals. The eventual output of the signals processed by the control module is secured through communication interface which bears field bus function. The cooperation between multi-path selection module and the signal conditioning module permits multiple signal accesses to each channel. The introduction of high accurate voltage references, pl
