Current voltage analogue signal conditioning module for dispersive actuation system (DAS)

The invention relates to a current voltage signal conditioning module for dispersive actuation system (DAS). Current or voltage analogue signals are converted to be 0V-5V voltage signals by an analogue signal conditioning module, and are fed into an AD (Analogue-to-digital) sampling module to carry out analogue-to-digital conversion; output digital signals enter a FPGA (Field Programmable Gate Array) module which simultaneously reads a calibration value stored in a Flash module; the FPGA processing module output signals to an optical fibre module and a RS (Remote Sensing) 485 module by two signal wires CE and TXD on a port of a UART ( Universal Asynchronous Receiver Transmitter); the optical fibre module converts the signals to be light signals which are sent to a remote display module or a constant value module; the RS485 module converts the signals to be differential signals which are sent to a communication module or a local display module. The conditioning module is helpful for improving security level of an AP (Access Point) 1000 nuclear power plant, so that the reliability of the system is improved; moreover, the conditioning module has high current and voltage signal accuracy indexes, and a quick response speed.
